Final answer:
TIG welding uses a tungsten electrode to create an electric arc for high-precision welding in industrial applications. It allows for controlled, strong, and high-quality welds in high-temperature applications.
Step-by-step explanation:
The process that uses a tungsten electrode to set up an electric arc between the parts is known as Tungsten Inert Gas (TIG) welding. In TIG welding, a tungsten electrode is heated and creates an arc that melts and joins the material being welded. TIG welding is used for high-precision welding in various industrial applications, requiring a high level of control to produce strong and high-quality welds. It is commonly employed for high-temperature applications where precision and strength are critical, such as in the construction of furnace tubes, lighting tubes, melting crucibles, and other demanding engineering tasks. The use of a tungsten electrode ensures that the welding process can be carried out at the temperatures necessary to melt the base materials without the electrode itself melting, which results in a clean and controllable welding process.
