Applications, advantages and disadvantages of Electroslag welding (ESW)

Today I will be discussing on electroslag applications, advantages and disadvantages. Previously an articles was published on principles of electroslag welding. Check out!

• What is electroslag welding and its working principles

Applications

The followings are the applications of electroslag welding.

• It is used in plate industries where thick plate of about 80mm are 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

Some applications of electroslag welding 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, electroslag welding still offers some disadvantages. The followings are the limitations of this welding process.

• Slow rate of cooling gives columnar grain to the weld
• Very high heat applied to the base metals
• Proper cooling is needed for high temperature applied
• Only vertical position can be welded
• Offers low toughness to the weld
