Fusion Welding
Fusion Welding
A type of welding where the joint is completely melted using heat to form a bond. Filler material can be added.
Solid State Welding
Solid State Welding
A type of welding where the materials are joined without melting. It relies on pressure to bond the pieces.
Forehand Welding
Forehand Welding
A welding technique where the torch is held above the metal plate with an angle of 30° to 45° from the horizontal plane.

Study Notes
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.
