When most of us think of welding, we imagine either open flame or electrical arc as the energy source. The metal is brought to the liquid or molten phase in the joint, and with or without filler material, the metal is joined. But cold welding is nothing alike. There is no molten phase, no electrical arc, and no flame as an energy source.
Welding is a broad field with tens of welding processes, each used when it's best suited. You can see everything from laser and resistance to cold welding in professional applications. But the four most prominent and most widely used welding processes are MIG, TIG, Flux-Cored, and Stick welding processes. These are manual, but they can also be automated. This article discusses these four processes from a hobbyist and a beginner welder perspective. You will learn what they are, how they work, their advantages, disadvantages, and when to use each of them.
