Description
Students will learn how to set up and run an SAW machine and make acceptable welds. Submerged Arc welding is a process wherein an electric arc is submerged or hidden beneath a granular material. The process is either semi-automatic or fully automatic. The arc meets the wire, base metal, and flux in a common pool. The arc is not visible since it is buried in the flux, thus there is not flash or spatter. Submerged arc is best adapted where relatively thick sections are to be joined, because of its high deposition rates. Students will learn proper SAW welding techniques for welding on 1? mild steel plates.

? Weld single pass fillet weld in tee joint 8? long
? Weld 1? multiple pass fillet weld in tee joint 8? long
? SAW 1G certification plate on 1? mild steel plate
? Prepare plate for destructive testing by cutting 3/8? side be
