Advantages of Electroslag welding

• Due to the slow cooling rate, cold cracking does not occur.
• High productivity can be achieved.
• It is a Low-cost process.
• In this process, slag inclusion or porosity does not affect.
• This welding process is faster.
• This is a semi-automatic process.
• The slag remaining is eliminated.
• A heavier section can be welded in a single pass.
• This process can weld Heavy parts easily.
• Low distortion.

Disadvantages of Electroslag welding:

• It required additional cooling for high-temperature welds.
• The quality of the welding decreases in the fusion zone and the heat-affected zone if the supply of heat is high.
• Cracking may occur in the heat-affected zone.
• It is only useful for vertical position welding.
• It has low toughness to the weld.
• Due to the high heat base meat gets hotter.
