Webb15 apr. 2024 · A similar HI value on stainless steel that is 1/8 in. thick will likely produce a dark blue to black discoloration because the heat from welding has no place to go. The easiest way to reduce HI is to increase travel speed, assuming you have a voltage and amperage value that is producing the desired welder-friendly arc characteristics. WebbThat buildup is the oxidization of the stainless at welding temps. The only way to prevent that is a purging gas or shield material covering the welding area. If any crystals form, …

WebbRemoval of weld discoloration. During welding, some discoloration, which is a thin oxide layer, will be evident in the heated area near the weld. Mechanical removal or this heat tint should be limited to clean glass bead blasting, flapper wheels, aluminum oxide discs, and wire brushing with austenitic stainless steel wire brushes. Webb4 maj 2004 · The stainless steel then is rapidly cooled (through the temperature range of 1,600 and 800 degrees F, or 870 and 425 degrees C) to inhibit carbide precipitation, and then at lower temperatures exposed to air, where the protective oxide film forms spontaneously.
