WELDALLOY 886
For Joining and Repairs of
Manganese Steel Parts.
WELDALLOY 886 is an exceptional low heat input
high alloy austenitic electrode for joining and
overlaying manganese steel and for joining these to other steels. The deposit is work hardening
type and highly resistant to cracking and
deformation during working. Prolonged life has been obtained even under simultaneous impact and abrasion.
Clean the damaged, worn out metal and/or cracks either gouging or grinding, Use lowest possible
current. Do not exceed the interpass temperature of manganese steel components during welding
to over 1000C. This can be done either by stringer beads or by suitably extracting heat from the component during welding.
Tensile Strength (Typical) : 60-65 kgf/mm2
Elongation : 30-40%
Hardness (As welded) : 180-210 BHN
After work
hardening :
500-550 BHN
WELDALLOY 886 is immensely suited for joining and repairs of manganese steel parts used in construction, earth moving and mining industry such as shovels excavator and draggling buckets,
sprockets, hammers, crusher rolls, track pads and rock crusher, jaws, cones, gyratory crusher, manganese rails etc.

WELDALLOY 816 S
For Stainless Steel Overlays.
WELDALLOY 816 S is a high efficiency stainless
steel electode, which is easy to operate and fast
depositing type for surfacing work. The weld metal is strong, ductile and tough.
Clean weld area from oil, grease, dirt and rust suitably. Use short arc, avoid weaving, chip slag between passes to avoid slag inclusion. Give thin layer deposit by faster hand motion.
Tensile Strength (Typical) : 60 Kgf/mm2
Elongation (Typical) : 30%
Depositing tough stainless steel overlays on cast steel, austenitic manganese steel parts, rebuilding of impellers, shafts, valves faces and seats required to
resist heat, abrasion, erosion and corrosion.

Tensile Strength (Typical) : 60-65 Kgf/mm2
Elongation (Typical) : 30-40 %
Hardness (As deposited) : 80-100 RB
After work
hardening :
28-32 RC
WELDALLOY 886 S is designed for joining and repairing of manganese steel including Hadfield
steel used in mining, construction and earth moving industries. Very much suitable for application like shovel, excavator and dragline buckets of various
capacities, sprockets, crusher rolls, trackpads, crusher jaws, hammers, crusher mantle etc.

WELDALLOY 307 S
For Extremely Tough Buffer Layer.
WELDALLOY 307 S is a high deposition efficiency electrode for depositing an extremely tough
buffer layer prior to hard surfacing or joining of dissimilar sections of steel.
Clean area to be welded of damaged, fatigued, cracked metal by gouging or grinding. Use lowest possible current, short arc and stringer bead.
Avoid weaving.
Tensile Strength (Typical) : 60 Kgf/mm2
Elongation : 35%
Hardness (As deposited) : 200-230BHN
After work
hardening :
500-550BHN
The electrode ideal for overlaying or for giving a buffer layer on cast steel prior to hard surfacing for rebuilding of austenitic manganese steel, carbon or low alloy steel. It is also ideal as a cushioning layer on
diamond crossing, frog forging hammer repairs and build-up, anvil repairs and many similar application
where impact loading is involved such as crusher, bucket, teeth, wear plates, sprockets etc.

WELDALLOY 980
A Truly Versatile electrode for High Strength, Crack Resistant Deposit for Joining Unknown Dissimilar Steels.
WELDALLOY 980 is an ideal electrode for making joints in unknown dissimilar steels. The carefully controlled ferritic austenitic duplex structure
provides very high strength. The overlay with this
electrode is very tough and wear resistant.
Remove any visible cracks and damaged material. Use short arc and lowest possible current. Employ short stringer beads using skip and staggered welding sequence. Chip slag between passes and peen the deposit when it is hot.
Tensile Strength (Typical) : 85 Kgf/mm2
Hardness : 210-230 BHN
The electrode is useful for joining and repairs of heavy machinery parts. Earth moving equipment parts, automobile springs and parts subject to heat,
corrosion and impact. It is also useful in joining and surfacing high carbon, low and high alloy steels, case
hardening steels, cast steels, high speed steels, tool steels, spring steels, manganese steels, suitable for surfacing of grooved rolls and repairs of drop forge.
It is ideal in rectifying worn out splines, threads, key ways in shafts, spur gear tooth, gear box main and
counter shafts, buckets, tool dies, leaf and coil springs and joining wearplates, repair of pinions, gears, buckets etc.
