Maintenance Welding

A Special Electrode That Deposits A Weld Metal Whose Composition Matches That Of Standard Cast Irons

CIN-3


PRODUCT DESCRIPTION

A chemically basic flux coated electrode that contains a high proportion of amorphous graphite and ferro alloys for deoxidation and grain refinement. The flux is extruded into a mild steel core wire using a blend of silicates that ensures coating strength and stability

WELDING FEATURES OF THE ELECTRODE

The electrode welds with a soft, stable, low penetrating arc on both AC and DC. The cone at the end of the electrode is rather shallow so it is necessary to maintain a constant arc. The weld seams are slightly convex but smooth and the electrode shows great tolerance to porosity on contaminated surfaces

APPLICATIONS AND MATERIALS TO BE WELDED

The weld deposits are non-machinable but of matching colour to that of standard cast irons and is thus used for the rectification of initial cast irons and repair build-ups on cast irons that have become worn or damaged in use. Because of the high hardenability of both the weld metal and base materials, a pre-heat of minimum 200 ºC is essential as is slow cooling

OTHER DATA

Electrodes that have become damp should be re-dried at 150oC for 30 minutes.
