The American Welding Society defines a joint as “the manner in which materials fit together.” there are five basic types of weld joints:
• Butt joint.
• Lap joint.
• Corner joint.
• Edge joint.
1. Butt joint:
Butt joints are end to end joint, in which the parts lie in the same plane and are joined at the ends.
In a T-joint (also called as Tee Joint), one part is at the right angle to the other part and it forms a shape similar to alphabet “T”.
3. Lap joint:
In Lap joint, two overlapping parts are joined together.
4. Corner Joint:
In corner joint ends of the adjoining parts are joined, parts are placed at right angles to each other.
5. Edge joint:
The adjoining parts in edge joints are kept parallel with each other with a common edge and the joint is made at the common edge(s).
