One thing to understand is how to use a reducing flame to keep as much oxygen away from the steel as possible. Practice every time you work. Therefore if you do not use flux you must raise the temperature enough to make the elements on the surface fluid. Nicely done Steve, and much appreciated. Keep in mind that everyone has their own way of forge welding, so you’ll probably hear people use other methods. Consequently, the forge welding flux serves as a low-temperature glassy shield that prevents the oxygen from the steel surface, which causes scales on … Because Flux core welding is a ‘hot’ process compared to MIG welding, welding thinner than 20 gauge will take skill or risk blowing holes through your metal.
