WIPWeld 310 (AWS E310-16)

A stainless steel electrode with basic coating for welding of austenitic, heat-resistant Cr-Ni steels of the type 25Cr/20Ni (NCT, AISI 310 Ugine NS 30, Avesta 254E, SanDvik 15E10). Weld deposit has flat regular beads with easy slag removal. Heat resistant up to 1200°C in oxidizing sulfur-free atmosphere.

Applications and Directions

Furnace linings, furnace grates, burners, etc. Also for welding steels with high carbon content. For joining dissimilar metals and hard to weld steels.

Prepare and fit the work carefully, cleaning the joint of all foreign material. Use DC+ or AC current with minimum open circuit voltage of 70 volts. Proceed with the lowest current possible and a short arc without allowing coating to touch the molten pool. Short and intermittent welding should be preferred to avoid overheating and distortion. Avoid excessive weaving. Electrode should be coated. discard exposed core wire. Use only dry electrode to prevent blowholes in deposit. If necessary, re-dry at 250 degrees celsius 2 hours before use.
