WebOct 5, 2024 · The heat for welding comes from an electric arc that streams from a tungsten electrode in the torch. Over the years, welding engineers have found many ways to tailor these electrodes for specific applications by adding small amounts of exotic elements to the tungsten. The different types of electrodes are identified by a band of color at one end. Surface oxidation is one thing, but deeper oxidation, below the face of the metal, causes porosity. This is where shielding gas or flux comes in, as both are designed to protect the hot welded area from the atmosphere until the bead/HAZ cools to the point where the steel/atmosphere mash-up won’t hurt the steel’s … See more First things first: Why does steel change color? There’s a lot of science involved and maybe some magic. I’m terrible at explaining science, and chances are you’re not fond of … See more Arc length, bead length, temperature of base material, how clean and smooth the surface is, tungsten angle, your motion while welding, the direction you’re welding, if there’s a back purge or backing plate, and post flow all … See more
