DESCRIPTION
V-Ni-CrFe-2 is a nickel-chromium-iron flux-coated electrode designed primarily for shielded metal arc welding of Incoloy® 800 to itself or to 9% nickel steels. This electrode is used for welding a variety of dissimilar wrought or cast forms of carbon steel, austenitic and ferritic stainless steel, and nickel-chromium Inconel® 600 to themselves or to each other. VOLTAWELD V-NiCrFe-2isfrequently used for joining Incoloy® 800 to high nickel alloys 200 and 201 or to nickel-copper Monel® 400 and K-500.
APPLICATIONS
V-NiCrFe-2 is excellent for overlaying nickel-chromium alloy on steel. More common applications include the welding of 5% and 9% nickel steel transport or storage tanks used for cryogenic products. The chemical or petrochemical industries use.
V-Ni-CrFe-2 for many applications such as valve seats and gates, coal gasification and wet process desulphurization equipment.
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.
