Although welding and metal fabrication are often used synonymously, they are different processes. Welding is the process of fusing two pieces of metal together while fabricating is a complete project in which welding is often used. This guide explains the differences between these two tasks.

Welding

Welding is the process of connecting two pieces of metal, glass, or thermoplastics together using fusion. Using intense heat, welders melt the base, or parent material, and add a filler to create a pool of molten material. This molten material cools and becomes a joint, which is usually stronger than the parent material.

Welders can bend materials by heating the metal, and they’re the fastest and most accurate in their craft. These professionals are considered specialists, and some shops won’t allow welders in other aspects of the fabrication process.

Metal Fabrication

Fabrication uses engineered drawings or 3D renderings to complete a project. Several processes are used to create the project, such as cutting, which is accomplished with torches, lasers, or water jets. The material is also bent and shaped by hammers and tube benders. Lastly, the piece is assembled by welding it, applying adhesives, and using riveting. Fabrication can also include other processes, such as die-cutting, stamping, and stretching.
