DESCRIPTION
V-NiCrMo-2 is a nickel-chromium-molybdenum electrode developed for shielded metal-arc welding of similar base metals such as Hastelloyl® X to themselves or to stainless steels and low alloy steels. VOLTAWELD V-NiCrMo-2 offers an exceptional combination of oxidation, corrosion and thermal shock resistance. This electrode exhibits high temperature strength and prevents weld metal fatigue at temperature as high as 2200ºF
APPLICATIONS
N-NiCrMo-2 is commonly used in the chemical process industry for retorts, muffles, catalyst support grids, furnace baffles. It is also used for engine tailpipes, turbine blades, afterburner components, nozzles vanes, cabin heaters and other aircraft related parts.
INSTRUCTION FOR WELDING
(1) Its weldability is as same as austenitic stainless steels.
(2) Keep the interlayer temperature under 100ºC and cool it as fast as possible.
(3) Keep the welding current as low as possible.
(4) Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.
