Solid Wire Electrode BA-WIRE 625 for Submerged Arc Welding
Classification:
EN ISO 18274: S Ni 6625
SFA 5.14: ERNiCrMo-3
Main Application
BA-WIRE 625 welding wire has been developed for welding INCONEL alloy 625, INCOLOY alloy 825, INCOLOY alloy 25-6MO, alloy 20, welding the clad side of joints in steel with nickel-chromium molybdenum alloys, cladding steel with nickel-chromium molybdenum weld metal, surfacing of mild steel and for dissimilar welding of stainless steels to nickel alloys and carbon steels. The weld metal is highlyresistant to stress corrosion cracking and pitting.
BA-WIRE 625 is recommended for applications with operating temperature range from cryogenic to 540 °C.

Suitable fluxes: BF 38, WP 380
Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
