Description and Applications

  • Joint and build-up welding on multi-alloyed aluminium-bronze. Build-up welding on steel and copper alloys. Fusion welding between steel and aluminum-bronze(also multi-alloys). Suitable for MIG-brazing of aluminium surfaced and galvanised steels. For using in shipbuilding, machine, apparatus and pump construction; for example ship propellers, pump casings, valve control casings and food containers. Preheating necessary only with large workpieces. For the first run of build-up welds on ferrous base material we recommend pulsed-arc welding. The welding deposit is saltwater and corrosion resistant as well as wear resistant. Well suited if subjected to wear by salt water, cavitaion and erosion at the same time.
