Webbprocess for stainless steel is frequently GTAW due to its comparatively easier applicability and better economy. The heat of the arc produced melts the base metal and produces a weld pool. In contrast to normal arc welding, in GTAW, an inert gas shields the weld area in order to prevent air from contaminating the weld. This shielding gas prevents WebbThe temperature is much higher in the weld pool (>770 °C) than in the surrounding workpiece [ 16 ]. Thus, the upper part of the workpiece (−10 mm < z < −8 mm) is defined as the high-temperature region (>770 °C) and has a magnetic permeability of approximately 1.
