GTAW – Carbon Steel Pipe – Module ID 29304-16

$20.00

Module Four (29304-16) presents gas tungsten arc welding (GTAW), a unique welding process that requires the welder to coordinate the use of both hands since the filler metal is fed manually. GTAW can be used on critical piping and may sometimes be used for the root pass on pipe welds when other processes have been directed for the remaining passes. GTAW is also excellent for welding thin materials such as auto bodies. This module provides instruction in the use of GTAW for carbon steel pipe welding, including guided practice.
