Mechanical Properties of weld metal
|
| Cast-alloy 99 |
| Suitable for all
position welding of thin section where
maximum machinability is required. Since
the core wire is + 99% Nickel, weld
deposits are soft, can be shapped,
milled, drilled or tapped with colour
matching of parent metal. |

Cast-alloy 55
|
| Suitable for all
position joining of Cast Iron, Malleable
Iron ^ ductile iron to M.S.S.S., high
Nickel alloys or itself. Since the core
wire is 55% Ni-45% Fe, which produce weld
deposit with much lower weld shrinkage
stress and hence reduce cracking. |

| Cast-alloy EST |
| Suitable for
repairing of various cast irons where
machining is not required & where
weld shrinkage is of no concern. Since
core wire is of steel, the strenght of
weld deposit will be hihger. This is most
economical base electrode, does not
contain nickel, hence useful for repair
of castings, machine parts where
machining is not required. |
