Question

Difference between submerged arc welding and electroslag welding

Answer 1

• Their are many differences between sub merged arc welding and electroslag welding.
• Submerged arc welding arc as the heat source, the flux mainly mechanical protection and metallurgy. Electroslag welding in the slag pool as a heat source,, in addition to the flux to protect the weld pool and the metallurgical effect, the main point is the thermal effect (slag resistance heat).
• The penetration achieved with ESSC is less than that with for SASC -as the molten slag pool is used to melt the strip and some of the parent material.
• ESSC uses higher welding currents than SASC - so the welding heads used are more heavy duty.
• In ESSC Increased deposition rate of 60% to 80% than in SASC.
• Only half of the dilution (10%–15%) from the base material due to less penetration in ESSC than of SASC.
