WLD 295 - GMAW and Welding Fundamentals


Credits: 3
2 Lecture Hours 2 Lab Hours

Description
This course is designed for students in the Sheet Metal Apprentice program.  Students learn techniques for the welding of sheet metal 12 gauge and lighter.  Emphasis is placed on welding safety to prevent accidents.  Additional topics include the basic maintenance and operation of cutting torches and gas metal arc welding (GMAW) equipment. Students practice welding fundamentals taught in both flame cutting and multiple position welds on black iron in the GMAW process.
Learning Outcomes
Upon successful completion of the course, the student will:

  1. Correct dangerous situations in the weld shop which could result in an accident.
  2. Explain reasons for all personal protective equipment (PPE) used during welding processes.
  3. Describe principles of metal transfer in reference to application of process and definition of each.
  4. Choose an appropriate shielding gas given base metal and type of metal transfer.
  5. Explain applications of polarity in terms of penetration of base metal and application to both solid and flux cored wire.
  6. Calculate wire feed speed given base metal to weld and wire size.
  7. Assemble a flame cutting torch.
  8. Set correct gas pressure for flame cutting operations.
  9. Make both piercing and end cuts with a gas torch assembly.
  10. Set up a plasma torch for cutting black iron material.
  11. Make both piercing and end cuts using plasma torch equipment.
  12. Perform maintenance and minor repair operations on GMAW equipment.
  13. Execute butt, lap, tee and outside corner welds on 12 gage black iron in flat, vertical and overhead positions using solid wire.
  14. Execute butt, lap, tee and outside corner welds on 16 gage black iron in flat and vertical positions using solid wire.
  15. Execute butt, lap, tee and outside corner welds on 12 and 16 gage black iron in flat and vertical positions using flux cored wire.
