DESCRIPTION

V-NiMo-7 is a nickel-molybdenum flux-coated electrode developed specifically for welding similar base metals such as Hastelloy® B-2 to itself or to steel and nickel alloys.  Common base metals that can also be welded would include ASTM B333, B335, B619, B622 AND B626 all of which have UNS number N10665.

VOLTAWELD V-NiMo-7 has a controlled low level or carbon, iron and cobalt which together with nickel and molybdenum gives this electrode excellent resistance to pitting and stress corrosion cracking commonly caused by acids.

APPLICATIONS

The most common application of V-NiMo-7 would be in the chemical processing industries on parts exposed to all concentrations and temperatures of hydrochloric acid.  It is also used on parts subjected to sulphuric, phosphoric and acetic acids. VOTLAWELD V-NiMo-7 should not be used in the presence of cupric or ferric salts which may develop where iron or copper bearing alloys have come in contact with acids.  

NSTRUCTION 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.
