The variations between these processes lead to different strengths and weaknesses, which are important to understand in selecting the appropriate welding technique for specific tasks.
-
Welding Method:
The welding method refers to the technique used to join metals together. TIG (Tungsten Inert Gas) welding employs a non-consumable tungsten electrode to produce the weld. In contrast, Arc welding uses a consumable electrode to create an electric arc. This fundamental difference affects how the welds are formed and the overall quality of the finished product. -
Heat Source:
The heat source in TIG welding comes from the controlled arc generated between the tungsten electrode and the workpiece. Arc welding, conversely, generates heat through an electric arc created between the consumable electrode and the base metal. This difference impacts the temperature control and precision available in each process. -
Electrode Type:
The electrode type differs significantly between the two methods. TIG welding uses a non-consumable tungsten electrode that does not melt during welding. Arc welding relies on a consumable electrode that melts to fill the weld joint. This variation influences the quality and appearance of welds, as TIG typically produces cleaner and more precise welds. -
Materials Compatible:
TIG welding is versatile and suitable for welding thin materials and alloys like aluminum and stainless steel. Arc welding, however, excels with thicker materials and is commonly used with metals such as mild steel. Understanding the material compatibility is crucial for effective welding. -
