WebMar 16, 2024 · Lower heat is again critical during out-of-position GTAW. A weave technique can be used, but it is not as critical as it is with GMAW or SMAW. Fabricators would not make a welding process change to GTAW to improve out-of-position welding, but those who are already using GTAW can successfully use the process for these welds. WebAug 11, 2009 · The WPS will determine if the hot pass is SMAW or GTAW but if the procedure is (very common) a TIG root/hot and then stick it out, the main reason that the hot pass is TIG is so that you do not blow through the root pass. SMAW on top of the TIG root can be done without blow through but it is more risky. a. b wordsworth author
