There are five different types of welded joints for bringing two parts together for joining.
Five types of welded joints are butt joint, corner joint, lap joint, tee-joint and edge joint.

1. Butt joint:

In Butt welded type, the parts lie in the same plane and are joined at their edges.

2. Corner joint:

The parts in a corner joint form a right angle and are joined at the center of the angle.

3. Lap joint:

Lap joint consists of two overlapping parts.

4. Tee-joint:

In a Tee-joint, one joint is the right angle to the other joint in the approximate shape of the letter “T”.

5. Edge joint:

The parts in edge joint are parallel with at least one of their edges in common and the joint is made at the common edge(s).
