Web25 aug. 2024 · Problem #4 – Too Large Of An Electrode. Using a big electrode on thin steel is a surefire recipe for burn through. Welding 1/8″ steel with a 5/32″ stick rod is overkill! The amount of heat is simply too much for 1/8″ steel to handle. When welding thinner metals, try sizing your electrode accordingly. Web6 mrt. 2024 · Burn through definition is: “ Burn through in welding is a term used to describe the unwanted progression of heat through the base metal and causing a hole or cavity to form. In simple words- you melt through the base metal. With this term, burn-through is also known as melt-through in welding .”
