SYLLABUS

 

Course Description

WLDG 1434: Introduction to Gas Tungsten Arc Welding.  An introduction to the principles of gas tungsten arc welding (GTAW), setup/ use of GTAW equipment, and safe use of tools and equipment.  Welding instruction in various positions and joint designs.  Course Fee: $50.00;  Course Type: W

 

Course Objectives

Students take this course typically to satisfy one of the following objectives:

  • You are pursuing a Certificate or an Associate of Applied Science degree in Welding Technology at Austin Community College, and this course is one of your curriculum requirements.
  • You are pursuing a course of study in a related industrial technology offered at Austin Community Col­lege, and this course would be helpful in your career objectives.
  • You have been employed previously in the field of welding technology, but have not had an opportunity to develop skills in the inert gas processes.

 

End-of-Course Outcomes

Describe various joint designs; describe safety rules and equipment; and describe the effects of welding parameters in GTAW; weld various structural materials.

 

Credit and Format

You will receive four hours of college credit when you successfully complete this course.  Dur­ing the fall and spring semesters, the course will meet for sixteen weeks scheduled in one of the fol­lowing formats: (1) twice weekly for 2:35 hours per class, or (2) once weekly for 5:20 hours per class.  During the summer, the course will meet 16 times: (1) twice weekly for 5:10 hours per class.  Regardless of format, the total class time for this course is eighty clock hours.

Tuition is charged at the rate posted in the current Course Schedule, depending upon whether you live in-district, out-of-district, or out-of-state.  In addition, there is a $50.00 course fee to cover welding electrodes, gases, practice metal and incidental consumables, plus a $1.00 per course fee which provides you with an accident insurance policy ($25.00 deductible).

 

Attendance/ Class Participation

Regular and punctual class and laboratory attendance is expected of all students. If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class.  If you accumulate unexcused absences exceeding 10% of the total eighty clock-hours re­quired for this course by the Texas Higher Education Coordinating Board, you will be dropped from class.  You will receive the grade of W.  If the final semester withdrawal date has passed, you will receive the grade of F.

Your absences will be recorded on the last page of your Projects List presented at the back of this syllabus.  It is your responsibility—not your instructor’s—to keep track of your absences.

Excessive absences result in (1) your failure to progress towards the objectives of the course, (2) unfair demands on your instructor's time by taking him/her away from respon­sible students in or­der to catch you up on missed assignments, and most important (3) you become an increased safety risk due to your diminished familiarity with hazardous equipment and safety protocols.

 

Important Information on Advising

If you have decided to pursue a degree or certificate in Welding Technology, it is essen­tial that you obtain departmental advising immediately.  There are several critical obliga­tions that stu­dents overlook, then later expect the College to make exceptions for their oversight when the time comes to graduate.  It is your responsibility to obtain a copy of the ACC College Catalog and stay informed of your obligations:

  1. Failure to Follow a Degree or Certificate Plan:  It is imperative that you adhere to a weld­ing degree or certificate plan outlined in the ACC College Catalog current at the time of your initial enrollment.  It is your responsibility to seek out the ap­propriate departmental advisor to work with you in preparing a degree plan, and to approve restricted electives, course substitutions, and course challenges (if al­lowed).  Failure to do so can result in your graduation application being denied until such time that you comply with College policy.
  2. Texas Success Initiative (TSI):  Texas law created the Texas Success Initiative (TSI), which requires all degree-seeking students to take the Texas Higher Education Assess­ment (THEA) test or an approved alternative.  Students may forgo TSI as­sessment if they meet one of the waivers or exemptions listed in the ACC College Catalog.
  3. Inadequate Record Keeping:  From the time you first enroll, you should create a home file and keep records of your paperwork each semester.  As a minimum, these records should include your degree plan, TSI scores, enrollment records, payment receipts, and semester grade reports.
  4. Application for Graduation:  If you are eligible for graduation with a degree or cer­tificate in Welding Technology, you must submit your application for gradua­tion no later than the posted deadline.  This deadline comes early in the semester, so consult the current ACC Academic Calendarfor the exact date.  Then, apply for graduation through your student Online Services account.  Do not miss this deadline or you will for­feit graduating that semester.
  5. Failure to Apply for Certificates Before Applying for a Degree:  You cannot re­ceive a cer­tificate at the same time (or after) you receive your Associate of Ap­plied Science degree.  Certificates are progressive awards received in stair-step fashion on the way to complet­ing your associate’s degree.  You should apply for them as soon as you have completed their requirements—not wait until the same semester that you apply for your degree.  If you have a question, contact the ACC Graduation Office at (512) 223-7018.
  6. Minimum Grades for Graduation:  Only grades of C or better may be applied toward any degree, certificate, or award in Welding Technology.  This applies to courses taken at ACC and to credits transferred from any other institution.

 

Students with Disabilities

Each ACC campus offers support services for students with documented disabilities. Students with disabilities who need classroom, academic or other accommodations must request them through the Office for Students with Disabilities (OSD). Students are encouraged to request accommodations when they register for courses or at least three weeks before the start of the semester, otherwise the provision of accommodations may be delayed.

Students who have received approval for accommodations from OSD for this course must provide the instructor with the ‘Notice of Approved Accommodations’ from OSD before accommodations will be provided. Arrangements for academic accommodations can only be made after the instructor receives the ‘Notice of Approved Accommodations’ from the student.

Students with approved accommodations are encouraged to submit the ‘Notice of Approved Accommodations’ to the instructor at the beginning of the semester because a reasonable amount of time may be needed to prepare and arrange for the accommodations. Additional information about the Office for Students with Disabilities is available: http://www.austincc.edu/support/osd/

 

Scholastic Dishonesty

A student attending ACC assumes responsibility for conduct compatible with the mission of the college as an educational institution. Students have the responsibility to submit coursework that is the result of their own thought, research, or self-expression. Students must follow all instructions given by faculty or designatedcollege representatives when taking examinations, placement assessments, tests, quizzes, and evaluations.

Actions constituting scholastic dishonesty include, but are not limited to, plagiarism, cheating, fabrication, collusion, and falsifying documents. Penalties for scholastic dishonesty will depend upon the nature of the violation and may range from lowering a grade on one assignment to an “F” in the course and/or expulsion from the college. See the Student Standards of Conduct and Disciplinary Process and other policies at http://www.austincc.edu/current/needtoknow.

 

 

 

SCANS Competencies

The U.S. Department of Labor appointed a Secretary's Commission on Achieving Necessary Skills (SCANS) to determine the general academic and workforce skills needed to succeed in the workplace.  The Commission's purpose has been to encourage a vital national economy based on a highly skilled workforce.  The Welding Technology Department at Austin Community College incorporates these SCANS competencies into its course offerings by means of classroom instruction, lab exercises, student interaction, and specific work-related assignments.  A listing of the SCANS competencies for each welding course is as follows:

Student Rights and Responsibilities

Students at the college have the rights accorded by the U.S. Constitution to freedom of speech, peaceful assembly, petition, and association. These rights carry with them the responsibility to accord the same rights to others in the college community and not to interfere with or disrupt the educational process. Opportunity for students to examine and question pertinent data and assumptions of a given discipline, guided by the evidence of scholarly research, is appropriate in a learning environment. This concept is accompanied by an equally demanding concept of responsibility on the part of the student. As willing partners in learning, students must 
comply with college rules and procedures.

 

Annual Course Offerings

Below is the sequence in which courses are offered annually in the Welding Technology Depart­ment.  You should note that not all courses are offered each semester and should arrange your schedule ac­cordingly.  Advanced courses with low demand are scheduled only once an­nually, and in some cases, only when there is sufficient demand.

Withdrawal from Classes

It is the responsibility of each student to ensure that his or her name is removed from the roll should he or she decide to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or she feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records.

Students who enroll for the third or subsequent time in a course taken since Fall, 2002, may be charged a higher tuition rate, for that course.

State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.

 

Incomplete Grades

Strive to complete your work on time.  The grade of Incomplete is given only if you can substan­tiate why assignments were not completed due to an insurmountable schedule conflict that oc­curred after the final date for withdrawing from the course.  The Incomplete grade must be re­moved before the deadline during the following semester, or it will automatically convert to a fi­nal grade of F.  Consult the calendar in the current College Catalog for the removal date deadline during the following semester.  It is not your instructor's re­sponsibility to remind you of this date.

 

Grading Policy

Your final grade will be based on your progress throughout the semester in the areas of

applied skills (projects) and theory (examinations), weighted as follows:

1... Projects................................. 60%

2... Examinations........................ 40%

Your applied skills will develop as you progress through the Project List given later in this sylla­bus.  The Project List contains important accumulative projects, so your final applied skills grade will be based on the percentage of projects you complete.

Theory is also an important part of this course.  While applied skills are invaluable for learning what to do, a welding technician must also know the theory behind why things happen.  Your in­structor will provide appropriate written exams to measure your understanding of welding theory.

When calculating the above percentages, the following grading system is used at Austin Commu­nity College:

A—Excellent................. 90% - 100%.............. Grade Points 4

B—Good......................... 80% - 89%.................................... 3

C—Satisfactory............... 70% - 79%.................................... 2

D—Minimum Pass........... 60% - 69%.................................... 1

F—Fail............................. 59% - 00%.................................... 0

 

Makeup Work

If you must make up work at a class time other than that for which you are scheduled, you must comply with the following rules:

  1. You must sign in using the Attendance Sheet for the Welding Department found in the white notebook posted on the wall next to the hall door leading into Welding Labo­ratory 3122.  This is a liability insurance requirement.
  2. You must have the approval and supervision of a faculty member at all times while you are working.  You must notify that person when you arriveand leave.  You must not work unattended.
  3. When you have finished working, you must clean up your work area, sign out, and in­form the faculty member on duty that you are leaving.

 

For More Information

It is your responsibility to stay informed regarding the policies and deadlines that affect you as a student.  This information can be found in the following sources, which can be found online or in the Admissions, Student Services, or Financial Aid Office on any campus:

1.   Course Schedule (online)

2.    Academic Calendar (online)

3.   Student Handbook (free; also available online)

4.   College Catalog (nominal charge; also available online)

 

Use of ACC Email

All College e-mail communication to students will be sent solely to the student’s ACCmail account, with the expectation that such communications will be read in a timely fashion. ACC will send important Financial Aid, waitlisting, enrollment, and other information to this account and will notify you of any college related emergencies using this account. Students should only expect to receive email communication from their instructor using this account. Likewise, students should use their ACCmail account when communicating with instructors and staff. Instructions for activating an ACCmail account can be found at  http://www.austincc.edu/accmail/index.php.

 

Testing Center Policy

Under certain circumstances, an instructor may have students take an examination in a testing center.  Students using the Academic Testing Center must govern themselves according to the Student Guide for Use of ACC Testing Centers and should read the entire guide before going to take the exam.

To request an exam, one must have:

• ACC Photo ID
• Course Abbreviation (e.g., ENGL)
• Course Number (e.g.,1301)
• Course Synonym (e.g., 10123)
• Course Section (e.g., 005)
• Instructor's Name

Do NOT bring cell phones to the Testing Center. Having your cell phone in the testing room, 
regardless of whether it is on or off, will revoke your testing privileges for the remainder of the semester. 
ACC Testing Center policies can be found at http://www.austincc.edu/testctr/

ACC Safety Statement

Austin Community College is committed to providing a safe and healthy environment for study and work. You are expected to learn and comply with ACC environmental, health and safety procedures and agree to follow ACC safety policies. Additional information on these can be found at http://www.austincc.edu/ehs.  Because some health and safety circumstances are beyond our control, we ask that you become familiar with the Emergency Procedures poster and Campus Safety Plan map in each classroom. Additional information about emergency procedures and how to sign up for ACC Emergency Alerts to be notified in the event of a serious emergency can be found at http://www.austincc.edu/emergency/.

Please note, you are expected to conduct yourself professionally with respect and courtesy to all. Anyone who thoughtlessly or intentionally jeopardizes the health or safety of another individual will be dismissed from the day’s activity, may be withdrawn from the class, and/or barred from attending future activities.

 

Safety Regulations

Welding can become very dangerous—even fatal—if you are careless and neglect safety precautions.  Most accidents occur when people get in a hurry, so learn to pace yourself and move cautiously and deliberately.  The College endeavors to provide you with proper training and a safe environment, but you must also do your part by abiding by the following rules.  If you per­sistently violate these rules, you will be considered a safety risk and will be withdrawn from class:

  1. Wear your safety glasses at all times.
  2. Wear your ear plugs in areas of high noise levels.
  3. Know the locations and proper use of fire extinguishers.  They are located at the exit to every classroom and laboratory.
  4. Do not weld or grind near oxy-fuel tanks, manifold connections, or other potential sources for gas leaks.
  5. Beware of the signs of dehydration, especially during warm months: disorientation, confusion, light-headedness, flushed appearance, headache, exhaustion.  Do not wait until these signs appear—drink fluids and take breaks regularly.                                                                
  6. Be mindful of proper ventilation in your work area.
  7. When using portable grinders, be sure that you direct sparks away from others.
  8. When using stationary pedestal grinders, be sure that the tool rest is adjusted as close to the grinding wheel as possible without touching it (1/16”).  Always wear safety glasses when grinding and wire brushing.  Do not wear gloves when using pedestal grinders.
  9. Do not handle oxy-fuel equipment with oil or grease on your hands or clothing.
  10. Do not wear loose clothing or dangling jewelry when working in the lab; tie up long hair.
  11. Be sure that you have the proper shade of filter lens in your welding helmet or face shield.
  12. Do not attach your ground lead to water pipes or electrical conduit.
  13. When welding in a booth, keep your door closed.  When welding in an open area, shield your arc with welding curtains.  Always consider the line-of-sight between your arc and the eyes of bystanders.
  14. To avoid burns to others, do not discard hot metal without first quenching it.  Write “HOT” on objects too large to bring to the quench tank.
  15. Read Chapter 2:  “Safety in Welding” in your textbook by Larry Jeffus, Welding Principles and Applications, mentioned later in this syllabus.
  16. Report all accidents to your instructor without delay.  If you suspect an unsafe condition or an equipment malfunction, bring it to you instructor’s attention IMMEDIATELY.

 

Special Warning about Bloodborne Pathogens

A number of very serious Bloodborne Pathogens lurk in today’s public environments that can be devastating to your health—even fatal:

·HIV — Human Immunodeficiency Virus

·AIDS — Acquired Immunodeficiency Syndrome

·Hepatitis A, B and C

·Tetanus — “lockjaw”

·MRSA — Methicillin Resistant Staphylococcus Aureus

·Necrotizing Fasciitis— “flesh-eating disease”

If you sustain a nick, cut, puncture, abrasion, or any wound in which blood surfaces—however minor—cease all activity immediately and proceed to a First Aid Kit to apply antiseptic and a protective bandage.  Time is critical in treating Bloodborne Pathogens.  Notify your instructor, who will call Campus Police for further assessment, and if necessary, Austin Emergency Medical Services will be notified.

You will need to fill out the following forms, as appropriate, to activate your student liability insurance.  If your injury requires emergency room treatment, it is much easier to have your forms with you at the time of admittance.  It is infinitely more tedious getting signatures from treating physicians and hospital personnel days after the occurrence.  These forms are attached to the cabinet doors of the First Aid Kits:

1.Student Accident Liability Form

2.First Aid Log

3.Near-Miss Form

 

Laboratory Policy

1.   You must attend class at the time for which you are enrolled.

2.   When you complete a project, request approval from your instructor.  You will not be cred­ited for unproved projects.

3.   Cleanup time is ten minutes before the end of class.  Sweep your immediate work area and re­turn equip­ment to the tool room.  Surrounding work areas must be cleaned with the com­bined efforts of all stu­dents.

4.   Do not waste metal.  Cut away practice welds and consolidate pieces.  Do not remove metal from the shop.  This will help keep lab fees reasonable in the face of rising costs for steel.

  1. If there is an equipment malfunction, inform your instructor immediately so that it can be re­paired and returned to service.
  2. Smoking is not permitted on campus.

 

Supplies

You are preparing to enter the profession of welding, and like other technical crafts, it requires specialized tools and equipment.  Therefore, you will be required to purchase the following items.  Remember that quality tools cost more initially, but over time, they are actually less expensive.  They are more durable and will give you pride of ownership for years to come.  Please be aware that you will not be allowed to work in the lab if you are not properly dressed.

Withdrawal for Excessive Absences

 

WARNING—READ CAREFULLY!  If you accumulate unexcused absences exceeding 10% of the total eighty clock-hours re­quired for this course by the Texas Higher Education Coordinating Board, you will be dropped from class.  You will receive the grade of W.  If the final semester withdrawal date has passed, you will receive the grade of F.

 

Your absences will be recorded on the last page of your Projects List presented at the back of this syllabus.  It is your responsibility—not your instructor’s—to keep track of your absences.

 

Excessive absences result in (1) your failure to progress towards the objectives of the course, (2) unfair demands on your instructor's time by taking him/her away from respon­sible students in order to catch you up on missed assignments, and most important (3) you become an increased safety risk due to your diminished familiarity with hazardous equipment and safety protocols.

 

If it becomes necessary for you to withdraw yourself from this course, consult the calendar in the current Course Schedule for the last day to withdraw and still receive the grade of W (approximately two weeks before the end of the semester).  It is not your instructor's responsibility to remind you of this date.  If you are failing and do not withdraw in time, you will be locked in with no way to avoid the final course grade of F.

SAFETY AGREEMENT

 

By signing my name below, I am attesting that my instructor has made me aware that welding is dangerous if I ignore applicable safety regulations and laboratory policies.  I under­stand that I will acquire the knowledge of these regulations and policies by (1) reading the course syllabus attached to Safety Agreement, (2) reading the chapters on safety in my text­book (if applicable), (3) ob­serving all safety and warning signs posted in the laboratories and classroom, and (4) attending in-class safety demonstrations on equipment and shop practices given by my instructor through­out the course.  I understand that it is my responsibility to attend class regularly, be alert to my surroundings, and remain constantly vigilant to the risks of working in an industrial envi­ronment.  I understand that “safe practice” is the discretionary interpretation of my instructor, and that if I fail to adhere to these requirements—including the attendance policy outlined in the syllabus—I will be considered a safety risk to myself and others and I may be withdrawn or possibly fail the course.
