Underwater welding is a unique specialty within the world of welding, which we explore in this blog post, with input from welding instructor Keith Riggins. We discuss how underwater welding differs from welding topside, what safety precautions must be taken, and how welders can benefit from an underwater welding certification.
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.
In order to weld aluminum, you can use an AC TIG welder or MIG welder with an aluminum spool gun. Yes, you can weld it with other processes like laser beam welding and stick welding using a special electrode for this metal and in other ways. However, since most of the aluminum welding is done with these two processes we mentioned first, we will look at our YesWelder line of AC TIG and MIG welders for aluminum.
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.
