Electrodes - Cast Iron PLATINUM NiFe
KEY FEATURES
> For hot or cold welding of cast to cast, or cast to steel
> High strength
> Available in blister handy-pack or 1kg re-usable pack
> Easy to use & suitable for low OCV (open circuit voltage) welding machines (>45V)
APPLICATION INFO:
> Recommended for repair and reclamation of all standard grades of grey / malleable, nodular, SG & austenitic cast irons and some grades of meehanite cast iron
> Stronger and more resistant to solidification cracking than the pure nickel electrode types (such as Ni-Cl)
> Fully machinable weld deposits
> Applications include: machine bases, pipes, gear teeth, pump bodies, heavy machine sections, flanges and pulleys
> Suitable for hot or cold welding (with or without preheating). Note that preheating and postheating is recommended for best results, see Cast-iron welding guide for more details
OPERATING INFO:
> Polarity: AC ± or DC ± (electrode + or -)
> Typical current range 3.2mm: 60-100A
> Minimum recommended OCV (open circuit voltage): 45V
> Ensure base material is clean.
> Use low current & keep short arc length.
> If welding restrained parts, use short staggered beads to minimise risk of cracking
> Avoid excessive current (heat) as this will increase risk of cracking
CLASSIFICATIONS:
> Classification: AWS ENiFe-CL
TYPICAL PROPERTIES OF ALL WELD METAL
> Tensile strength 500 Mpa (N\mm2)
> Composition %: C1.26 Mn0.80 Si0.66 P0.005 S0.003 Ni57.25 FeBal'
