Following safe practices should include
- describing and wearing appropriate PPE for GMAW operations (e.g., proper clothing, ear and eye protection, respiratory protection)
- describing and implementing the proper method for handling, storing, and setting up cylinders
- explaining and guarding against hazards (e.g., electrical, heat, light, fumes)
- discussing and implementing the proper methods for ventilating the welding area
- explaining and discussing SDS literature
- explaining and demonstrating the proper procedures for GMAW operations.
Process/Skill Questions:
- What is MIG welding and is it the same as GMAW?
- What is the GMAW process and why would one select this welding process over SMAW?
- What are some common safety measures that are required prior to MIG welding?
- Why would one need to use a skullcap under a welding helmet, and if so, what material should it be made of?
- How do surface contaminants adversely affect the welding current, reduce wire-feeding performance, and reduce weld quality?
