WebThe main advantage of extrusion welding is that it can achieve very high deposition rates of filler material into a joint, thus cutting down on cycle time. As compared to hot gas welding, which is a polymer welding process that could have many of the same applications, the time to completion for a weld is as much as 5-6x faster. WebThis Welding Safe Work Method Statement (SWMS) covers hazards and controls associated with welding work being undertaken either indoors or outdoors. Suitable for the following welding (hot works) types: stick, spot, MIG, TIG, Oxy-Acetylene, Gas Metal Arc Welding. This SWMS covers High-Risk Construction Work (HRCW) controls related to:
