Welding:
WELDING ALUMINUM ALLOYS (WAT 200)
Course Description
The participant should be able to select the appropriate welding process for aluminum, select
the appropriate filler metal, set up and adjust the welding equipment, and produce acceptable
quality welds on aluminum alloys.
Learning Outcome
The successful completion of this course should give the participant a working knowledge of
welding aluminum alloys, including:
1. types and uses of aluminum materials, work hardenable alloys, heat treatable alloys,
and cast alloys;
2. physical characteristics of aluminum, including: melting temperature ranges, thermal
conductivity, and the refractory oxide scale;
3. welding preparation and problem areas, including: safety procedures, operation
sequences, and weld quality problems; and
4. hands-on applications using Gas Metal Arc and Gas Tungsten Arc Welding processes,
including: process variations, equipment, and weld quality inspection.
Course Objective
The participant should have the skills necessary to weld aluminum alloys using recommended
welding processes and filler metals.
