INWE 40040 - GMAW of Aluminum 0.67 CR
The welding of aluminum using the MIG welding process is advantageous over the TIG process because heavier sections of metal can be welded much faster. Most fusion welding of aluminum alloys is done with the MIG welding process because of this reason. The equipment required for MIG welding consists of a drive system that pulls the electrode from a reel and pushes it through a welding gun. An argon shielding gas is also used to prevent oxidation and weld puddle contamination. In this module, the welding student will learn how to establish the arc and make welded joints using the GMAW aluminum process.
Course Learning Outcomes:
- Demonstrate the knowledge of the gas metal arc welding process by correctly setting up a GMAW system, including voltage, amperage, shielding gas, and all variables.
- Execute correct metal preparation for GMAW.
- Describe the fundamentals of Gas Metal Arc Welding (GMAW).
- Identify the GMAW process in comparison to other arc welding processes.
- Identify the basic GMAW electrode numbering system as established by the American Welding Society.
- Produce various weld beads, flat position welds, out of position welds.
- Produce GMAW Aluminum welds in the flat position.
