What is the primary purpose of welding in materials processing?

The primary purpose of welding in materials processing is to join materials together by melting their edges and allowing them to fuse as they cool. This technique is widely used in various industries to create strong and durable connections between metal components. When materials are welded, their edges are heated to a temperature that allows them to melt, after which they fuse upon cooling, forming a continuous and robust bond. This process can effectively combine different metals, allowing for the fabrication of complex structures, machinery, and components that require high strength and integrity.

Welding techniques can vary, including processes such as arc welding, MIG welding, TIG welding, and more, all tailored to the specific materials being joined and the requirements of the application. The resulting weld joint typically exhibits similar or superior mechanical properties compared to the materials being joined, making welding a fundamental method in the construction and manufacturing sectors.

Coating materials with a protective layer, separating materials into distinct parts, and measuring tensile strength serve different functions in materials processing and do not encompass the primary purpose of welding.
