The Gas Tungsten Arc Welding (GTAW) process, more commonly known as TIG welding, is a manual welding process that uses tungsten inert gas (TIG) to protect the weld from oxidization and contamination. A TIG welder uses either a continuous or pulsed arc to fuse metals. This process is often preferred by welders because of its…
Fusing Metal – welding is the process in which two pieces of metal are fused together using heat and or pressure. Welding is therefore a fabrication process that is a crucial part of the manufacturing operations and, as with any manufacturing processes, the welding procedure used to fabricate a part or structure is dependent on…
Reverse polarity welding and when to use it is a question that crops up regularly. It is an important topic as it will drastically affect the quality of the weld. To understand when you should employ reverse polarity welding you need to have a grasp of current and polarity as a whole. In this article…
