What is a common method for joining metal parts?

Welding is a common method for joining metal parts due to its ability to create strong, permanent bonds by melting and fusing the metal components together. This process typically involves heating the edges of the pieces to be joined using an appropriate heat source, such as an electric arc, gas flame, or laser, and may also include the addition of filler material to enhance the bond.

Welded joints can withstand significant stress and loading, making them suitable for a variety of applications, from automotive and aerospace to construction and manufacturing. The versatility of welding allows it to be used on different types of metals and designs, contributing to its popularity as a primary joining method.

Soldering, while also a joining process, primarily involves lower temperatures and is often used for connecting electrical components rather than structural metal parts. Machining and forging, on the other hand, are processes used to shape and form metal rather than join them, thus placing them outside the context of methods specifically designed for joining metal components.
