PRODUCT INFORMATION

WELDING PROCEDURE & TECHNIQUE

DESCRIPTION Xuper 2240 is an extremely versatile joining and re-build electrode specially formulated for gray, ductile, nodular and alloyed cast irons. This all-position electrode possesses a unique arc, which aids in removing harmful contaminants.

Xuper 2240 deposits weld metal having a crack-resistant structure. It is easily handled, produces little to no spatter and it welds with excellent fluidity and wash. Weld deposits are machinable.

Preparation: Prepare casting defect by chamfering with either Eutectic ChamferTrode® or ExoTrode®. Cracks should be prepared with drilled holes to prevent growth and either a single-V or double-V depending on casting thickness and accessibility. Allow a 1/8" root opening for full-penetration welds. Preheat large castings to 400°F (pre-heat temperature will vary with casting size, type and condition).

TYPICAL APPLICATIONS

Technique: Deposit short runs no longer than 2" and moderately peen the 2nd and subsequent passes. Use either a cascade or block deposition sequence (see figures below) for large sectional thickness castings.
