What’s up with the Plugs? Back purging stainless steel is the process of flooding the backside of a weld joint with an inert gas—usually argon—to remove oxygen and prevent oxidation during welding. This keeps the weld root clean, shiny, and corrosion-resistant, which is critical for high-purity piping, food-grade systems, and pressure vessels. @tigaesthetics #BNMBuilt #bnmmanifold #bnmtwinscroll #bnmfabrication #bnmfamily #bnmspecial #builtWrx #builtsubie #builtsubaru #builtsti #wrx #workhard #w

What is back purging and why is it critical in motorsport fabrication TIG welding? Purging is the process of removing the oxygen from the inside of an enclosed part prior to TIG welding. Removing oxygen from inside the part protects the back of the weld from oxidation due to the high heat of TIG welding enhancing the quality of the weld. This, in turn, maintains the corrosion resistance of parent materials, ultimately reducing leak rates and even structural failure risks of your finished work. I
