GMAW: Setting Up Aluminum Wire-Feed & Running Butt, T-Joints & Lap Joints is part six of the Welding with Gas Metal Arc six-part training series.
The course teaches how to weld aluminum with GMAW using aluminum wire for an electrode. It demonstrates how to weld butt joints, T-joints, and lap joints in flat and horizontal positions. The base metal used in these demonstrations is 3/32 inch aluminum. The wire electrode is .030 diameter aluminum wire. The recommended operating ranges for .030 diameter aluminum wire are 50 to 125 amps and 12 to 22 volts. The inert gas is straight argon and should be regulated to flow at a rate of 25 to 35 cubic feet per hour (CFH).
Course objectives include:
- List the safety precautions to observe when using GMAW equipment with aluminum wire
- Describe the procedures for welding butt joints, T-joints, and lap joints in flat and horizontal positions.
Our DVDs are portable and easy-to-use. Training content is "chapterized," or organized by learning objectives to:
- Help with course navigation
- Enable training administrators to cover specific training points and conduct refresher training
- Facilitate classroom discussion.
