Applications
The followings are the applications of electro-slag welding.
- It is used in plate industries where the thick plate of about 80mm is joined
- The welding process is used to weld large casting and forging when producing a large composite structure
- It is used for welding parts with thick walls with large-diameter parts, pressure vessels, storage tanks, and ships.

Advantages and disadvantages of electro-slag welding
Advantages
Some applications of electro slag welding ESW are stated below:
- Because of the slow cooling rate, cold cracking is avoided
- The process is semi-automatic and faster
- Slag remaining is eliminated
- Heavy parts can be weld
- Low cost for joint penetration
- Low distortion
Disadvantages
Despite its good advantages, electro-slag welding still offers some disadvantages. The followings are the limitations of ESW.
- A slow rate of cooling gives columnar grain to the weld
- Very high heat is applied to the base metals
- Proper cooling is needed for high-temperature applied
- Only the vertical position can be welded
- Offers low toughness to the weld
