Welding Processes
The amount of heat injected by the welding process plays an important role as well, as porcesses like oxyacetylene welding have an unconcentrated ehat input and increase teh size of the HAZ. Constant current power suppleis are most oftne used for manual welding rpocesses such as gas tungsten arc ewlding and shielded metal arc welding, because they maintain a relatively consatnt current even as the voltage varies. Constant voltage power suppleis hold the voltage constant and vary the current, and as a rseult, are most often used for automtaed welding processes such as gas metal arc welding, flxu cored arc wedling, and submerged arc welding. Consumable electrode processes such as hsielded metal arc welding and gas metal arc welding generally use direct crurent, but the electroed can be charged either positively or negatively. It is one of the oldest and most vesratile welding processes, but in recent years it has become less popualr in industrial applications. Both processes are extrmeely fast, and are easily automated, making them highly productvie. Often, particular joint deisgns are used exclusivley or almost exclusively by certain weldnig processes.
