WELDALLOY Ni
For Practically Pure Nickel Deposit.
WELDALLOY Ni provides a porosity free and crack
resistant deposit The deposit offers great resistance to corrosion and oxidation in many
severe environments.
Clean the weld area of any surface contamination. Use short arc and stringer beads in welding. Use as low current as possible and maintain low interpass temperature. Wherever possible weld in flat position.
Tensile Strength (Typical) : 40-45 Kgf/mm2
Elongation (Typical) : 25%
The electrode is suitable for welding of Nickel components or casting to themselves or to steels, for surfacing carbon and low alloy steels, for building up worn-out or missing sections and repairing defects, for cladding and overlays of mild steel for chemical, food, oil refining and caustic soda service. It is also
suitable for joining copper and copper alloys to
steel.

WELDALLOY NiCu
Stabilized Low Carbon Stainless
Steel Electrode.
WELDALLOY NiCu is easy to manipulate, stable arc electrode with excellent weld bead finish and slag
detachability. The dense porosity free deposit offers excellent resistance to sea water corrosion.
Clean weld area to be welded of oil, grease, dirt of
scale. Preheat the job between 100°C - 150°C
depending on thickness. Use short arc and weld
stringer beads. Whenever possible weld in flat
position.
Tensile Strength (Typical) : 48-52 Kgf/mm2
Elongation (Typical) : 35%
The electrode is useful for welding of monel and monel clad steels, for joining of monel to steel, overlaying of corrosion resistant monel on steel, repairing defects in monel components and casting, fabrication of chemical, food dairy pharmaceutical
and oil refining equipments.

WELDALLOY
NICRAFE-2
For Exceptionally Tough and
Heat Resistant Joints.
WELDALLOY NICRAFE-2 is a molybdenum bearing high nickel alloy electrode ideally suited
for applications where exceptionally high toughness and corrosion resistance at an elevated temperature is the perquisite condition.
Clean the weld area free of rust, oil, grease or any other surface contamination. Use short arc and stringer bead technique. If possible weld in flat position.
Tensile Strength : 55-60 Kgf/mm2
Elongation : 30 %
The electrode is a right choice for welding and
repairing incoloy type high nickel alloys which have good high temperature strength, creep resistance
and also oxidation and corrosion resistance. It can be used for welding of nickel, inconel, nickel chromium iron alloys and also for welding heat resisting HK, HT
type alloys and all grades of stainless steels.

WELDALLOY
NICRAFE-3
for Exceptionally High Crack & Heat Resistant Joints
WELDALLOY NICRAFE -3 is a high nickel alloy deposit which is very tough and has high resistance to scaling and corrosion. it possesses extremely good resistance to thermal shocks.
Clean the area to be welded of oil grease and scale. Preheat the job between 1000 C - 1500 C depending on thickness. Use short arc and weld stringerbeads, if possible weld in flat postion.
Tensile Strength : 55-60 Kgf/mm2
Elongation : 30 %
The high toughness, good heat corrosion resistance makes it highly suitable for welding of nickel, model, inconel, nickel chromium iron alloys, HK alloys, stainless and heat resistant steels to themselves or in various combinations. The electrode is a good choice for fabrication and reparing corrosion resistant tanks, conatiners, heat exchanger, furnace components, heating elements of nichrome etc.
