Hex weld nuts from ITA Fasteners are used to weld the nut onto a host material. (Source: American Welding Society) Many people prefer to equip their TIG holder with a “gas lens” which helps to focus the argon gas and improves shielding in the weld area. In addition to the risk of the corrosion of the weld joint is reduced because of adding the titanium element, the other performance is similar to 304 stainless steel. I know gray is too hot (which i dont get) so is blueish/purple too cold? So, here is Sparky's Question of the Day: Question: Which color is best in welding? type of steel, type of weld, loading on the welded joint, applicable codes, level of preheat, level of restraint, position of welding, condition of the steel, and service conditions. Figure 7B: Good color on stainless steel: 8. Reference color charts have been developed which show the heat tint on stainless steel weld roots as a function of purging gas type and oxygen concentration at the weld root (21, 22). For single pass welds, multipass welds which are not exposed, and multipass welds which do not require resistance to atmospheric corrosion and matching weathering characteristics, other filler metal combinations may be used. It would be an example of no color eh? Weld purging tools and technique F18S. Square butt. Welder, Name Finish Weld Symbol on Symbol base platform weld . Using AS/NZS 1554.6 effectively means rather more than requiring “Weld finishing to AS/NZS 1554.6”.
