Before diving deep into the types of welds and joints and how they work, you should understand their key differences.
A weld describes the technique used to fuse two materials via heat. There are four primary types of welds: tungsten inert gas (TIG), metal inert gas (MIG), flux-cored arc, and stick. The necessity of each welding process depends on a variety of factors, like the:
- Handler’s skill level
- Type of metal being used
- Industry and location the welder is working in
A welding joint, on the other hand, is an edge or point where these two pieces have been joined together. Depending on the welding technique, the joint can form into one of five designs: edge, lap, corner, butt, and tee joints. Each design directly impacts the quality, and welders should be mindful of making the right selection.
