Title: Describe procedures for welding aluminum, following all safety requirements, industry recommended practices, and instructor guidelines.
Course: Agricultural Fabrication and Emerging Technologies (18404) > Section: Performing Gas Metal Arc Welding (GMAW) Operations

Description should include

- determining the welder type, electrode, wire type, diameter, and gas to be used
- setting up welding equipment
- adjusting the welder for proper electrode stick-out, voltage, polarity, flow rate, and wire-feed speed required for the material being welded
- cleaning aluminum oxide surface
- determining ground clamp positioning and attachment.

Process/Skill Questions:

- What are the alternative methods for cutting aluminum?
- What types of welders are used for welding aluminum?
- What shielding gas would you use for performing GMAW operations on aluminum?
- What polarity is needed to weld aluminum?
- Why is a separate spool gun usually required for welding aluminum?
- How is the aluminum oxide surface removed?
- Why is it important to clean aluminum thoroughly before welding?
