What are the five basic weld joints?

The five basic weld joints include butt, tee, edge, lap, and corner. Each of these joints plays a crucial role in various fabrication and welding processes.

The butt joint is created when two pieces of metal are joined edge to edge, making it an essential joint used in a wide range of structural applications. The tee joint allows for a connection of two materials at a right angle, which is particularly useful for creating frames and supports.

An edge joint involves joining two workpieces together along their edges, often used for thin materials. The lap joint is formed when two pieces overlap each other, making it popular in sheet metal applications and providing good strength and alignment.

Lastly, the corner joint is similar to the tee joint but connects two pieces at their ends, forming a corner. This joint is commonly utilized in building frames and structures. Understanding these joints is fundamental for anyone involved in welding, as they determine the strength, accessibility, and the quality of the welds that can be achieved in various projects.
