WELDING DEFINITION
CLASSIFICATION OF WELDING
Welding processes are mainly classified as:
- Fusion welding
- Forge welding
Fusion welding
In this process the part to be joined are held in proper position while the molten metal is supplied to the joint. By heating the joint surface become plastic or molten. When the molten metal fuses the joint is formed.
Forge welding
In this type of welding the parts are first heated to a proper temperature in a furnace or forge and then hammered
Advantages:
In this type of welding the parts are first heated to a proper temperature in a furnace or forge and then hammered
The following are the advantages of welding
- Welded joints are greater in strength
- The process are noiseless
- Welded joint can easily be repaired
- Welded joints have low initial cost
- Less matching is required after welding
Disadvantages:
In this type of welding the parts are first heated to a proper temperature in a furnace or forge and then hammered
The following are the advantages of welding
- Welded joints can not be used for collision and vibration.
- Welded joints can not be assembled and reassembled.
