DESCRIPTION
V-Ni-CrFe-4 is a nickel-chromium-iron flux-coated electrode very similar to however VOLTAWELD V-NiCrFe-4 offers two distinct features that are not available with V-NiCrFe-4 offers a higher yield and tensile strength and it is formulated to operate with AC current, a feature that will allow to combat magnetic arc blow.
APPLICATIONS
V-NiCrFe-4 is designed for shielded metal arc welding of 9% nickel steel such as ASTM A333, A334, A353, A522, AND A553. However is can also be used for joining Incoloy® 800 to itself or to high nickel alloys 200 and 201. For joining Incoloy® 800 to 9% nickel steels or to nickel-copper Monel® 400 and K-500.
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.
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
V-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
(4) Its weldability is as same as austenitic stainless steels.
(5) Keep the interlayer temperature under 100ºC and cool it as fast as possible.
(6) Keep the welding current as low as possible.
(7) Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.
