DESCRIPTION
V-Ni-CrFe-1 is a nickel-chromium-iron flux-coated electrode designed primarily for welding Inconel® 600 and Incoloy® 825. Common ASTM base metals that can be joined are ASTM B163, B166, B167 and B168.
APPLICATIONS
V-NiCrFe-1 offers corrosion resistance over a wide range of environments ranging from cryogenic temperatures to approximately 1500ºF (820ºC). This allows VOLTAWELD V-Ni-CrFe-1 to be used in the chemical and food processing industries as well as for heat exchangers and evaporators. The most common use of this electrode would be for welding the clad side of joints in steel clad with Inconel® 600 and for surfacing steel.
INSTRUCTION FOR WELDING
(1) Preheating is not necessary in general.
(2) Avoid the continuous welding if possible. It is effective to weld under 150ºC for reducing cracking tendency.
(3) Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.
