Course Description

Advanced welding theory and practice, covering thermal cutting, oxy-acetylene welding and welding of ferrous and non-ferrous metals, qualification and certification requirements to Los Angeles City and the American National Standards Institute. May also enroll in WELD A215 for additional laboratory units. Each 54 hours of laboratory time earns one unit. Will be given credit for the laboratory course appropriate for the number of hours worked. Enrollment Limitation: WELD A200; students who complete WELD A201 may not enroll in or receive credit for WELD A200. PREREQUISITE: WELD A100 or WELD A101. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

  1. Join metals utilizing one of the welding processes (SMAW, GMAW, FCAW or GTAW).
  2. Weld metals in and out-of-position.
  3. Set up and use various welding and cutting apparatus.
  4. Correctly set up and use a constant current welding machine (SMAW and GTAW).
  5. Correctly set up and use a constant voltage welding machine (GMAW FCAW).
  6. Prepare metals for welding.
