Module ID 29302: This module covers basic concepts of open-root GMAW with pipe and describes how to prepare and perform open-root V-groove welds on medium- and thick-walled pipe. Gas metal arc welding (GMAW), also known as metal inert gas (MIG) welding, is a form of welding that joins two metals together using a filler metal wire electrode and a shielding gas. MIG welding is an effective method for making high-quality, open-root V-groove welds on pipe.

Module ID 29303: This module describes two primary approaches to FCAW and provides guidance for practicing the techniques. Flux-core arc welding (FCAW), also known as dual-shield welding, is excellent for pipe welding, although the root pass is seldom applied using FCAW. FCAW is a versatile process than can be performed with or without a shielding gas, depending upon the wire electrode used.

Module ID 29304: This module provides instruction and guided practice in the use of GTAW for carbon steel pipe welding. Gas tungsten arc welding (GTAW), also known as tungsten inert gas welding, is a unique welding process that requires the welder to use of both hands in the welding process. 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 excellent for welding thin materials, such as auto bodies.

Welders working on stainless steel must understand the differences between welding this type of steel and other types. The various grades of stainless steel require different welding techniques, filler metal composition, and heat treatments.

Module ID 29404: This module describes how GMAW equipment is used to weld aluminum pipe and presents the techniques used to produce V-groove pipe welds with backing. Gas metal arc welding (GMAW) is one of the more common welding processes. GMAW equipment is available in many different sizes and types—however, the basic operating principles of GMAW apply to all makes and models of equipment.

Module ID 29402: This module provides insight into welding aluminum using the GTAW process and an opportunity to hone the necessary skills. The GTAW process is unique in that the welder must add the filler metal using the opposite hand. The process is well-suited for welding aluminum, using the freehand or walking-the-cup technique and both stringer and weave beads.

Module ID 29403: This module provides insight into welding aluminum pipe using the GTAW process and the modified U-groove joint, which does not require a metal backing or a backing gas. The GTAW process is unique in that the welder must add the filler metal using the opposite hand. The process is well-suited for welding aluminum, using the freehand or walking-the-cup technique. Welders must understand that a significant amount of welding current is required for welding aluminum, especially when working with thick materials.

Module ID 29405: This module provides insight into soldering and brazing of copper. Soldering and brazing are welding processes that use nonferrous filler metal to form the weld joint. Soldering uses filler metal with a relatively low-temperature melting point. For joints that need to be mechanically stronger and more pressure-resistant, higher-temperature silver or copper alloy brazing filler metal is used. Oxygen/acetylene or air-acetylene fuel gases are typically used for brazing. Both soldering and brazing demand careful attention to safety due to the hazards associated with extreme heat, flammable gases and open flames.
