NICKELCAST

Specification

AWS Specification: N/A
JIS Specification: N/A
Other Specification: N/A

Description

NICKELCAST is a welding electrode that provides maximum strength for welding cast iron
Excellent crack resistance and porosity free
Soft arce prevents deep penetration
Weld deposit is easily machinable
No overheating of electrode
Special flux coating formulated to convert impurities of base metal into slag instead of being entrapped in the deposit
Little spattering and easy slag removal

Application

For fabrication and difficult repairs of all gray and alloyed cast irons
Recommended for welding cylinder heads, machine bases, gear housings, cams, levers, filling holes, reparing teeth of cast gears, and bulding up or replacing missing sections
Commonly used to weld ductile iron, "Ni-Resist" and "Meehanite" to themselves or to steel
Suitable for joining nickel alloys to gray cast iron, malleable cast iron, and cast steel

Remarks

Prepare weld groove with NIHONWELD NFG Chamfering rod

Remove gouged surface skin by grinding U shape

Thoroughly clean weld area, removing all oil and grease as far or as deep as possible

Preheat is not necessary but for heavy and complex section, a preheat of 100-200 degrees C is advisable

Ensure electrodes are dry

Use lowest practical amperage and maintain a short arc technique

When restriking the arc, start on previously deposited weld metal, not on the base metal

Weld short stringer beads (about 20-30mm long) only to prevent excessive heat build up

When breaking the arc, always fill the crater and drag rod back over the weld deposit
