Welding Classification

Welding is categorized into Fusion welding and Solid state welding.

Fusion Welding

Fusion welding involves melting the joint to be connected.
A molten filler material is typically added if necessary.

Solid State Welding

In solid state welding, no melting is involved.
Joints are formed by applying large forces.

Welding Joint Types

Lap Joint: Pieces overlap each other.
Butt Joint: Pieces are aligned side-by-side.
Corner Joint: Pieces are joined at a corner.
Tee Joint: One piece intersects another at a right angle.
Edge Joint: Pieces are joined along their edges.

Welding Methods

Fillet Weld: Used to join pieces at approximately 90° angles (e.g., T-joints, corner joints, lap joints).
Plug Weld: Used to join pieces in lap joints.

Welding Techniques

Forehand Welding: Torch is held above the metal plate at a 30-45° angle to the horizontal plane.
Backhand Welding: Torch is moved backward along the joint, allowing for continuous annealing and stress relief.

Welding Positions

Flat: Workpiece is flat.
Vertical: Workpiece is vertical.
Horizontal: Workpiece is horizontal.
Overhead: Workpiece is upside down.
