APR 186 - Wire Drive Welding 1

1-4 Credit(s)

Skills development in gas metal arc welding (GMAW) of carbon steel. Students will be instructed in proper care, set-up and use of GMAW equipment. Preparing weld test specimens and performing weld tests is included in this course.

Prerequisite: RD 087  AND EL 115  OR prior college or placement test.
Learning Outcomes
Upon completion of this course, the successful student will be able to:

  1. Set GMAW machine controls to effect short arc, spray arc and pulsed arc metal transfer while using solid wire of various sizes
  2. Select and properly connect to a GMAW power source appropriate shielding gases necessary to short arc and spray arc metal transfer
  3. Prepare typical industrial weld joints, make welds on these joints in the four standard positions, and perform destructive and non-destructive tests on those weldments
  4. Prepare materials, outline testing procedures, make welds, prepare test specimens, and execute testing procedures consistent with certain pre-qualified American Welding Society code tests
  5. Identify the type, cause, and solution to weld defects typically associated with GMAW short arc, spray arc and pulsed arc metal transfer
  6. Perform minor maintenance on GMAW equipment associated with contact tip, liner and drive rolls
