Description
This class will teach students how to setup welding equipment with the GMAW process for welding on aluminum. Aluminum presents special problems the welder dos not encounter when welding on carbon steel. It has a very low melting temperature, it will not support its own weight when heated to near melting temperature, it has a high affinity for oxides, and it relatively hard to clean. Students will learn how to deal with these problems and make sound welds on various types of aluminum using the GMAW process.

? Weld tee joints flat, horizontal, and vertical
? Weld lap joints flat, horizontal, and vertical
? GMAW aluminum 1G certification on ?? aluminum plate
? Prepare 1G certification for destructive testing
? Test root and face bends
? Evaluate bends for acceptable criteria
