The Dyeco Cast Iron Product Line of specially formulated products has been developed specifically to provide maximum weld integrity with enhanced weldability. Welding cast iron types such as gray, ductile, malleable, high strength spheroidal graphite (SG), compacted irons, etc. can be readily accomplished using welder-friendly DyecoTrode Cast Iron Products.
DESCRIPTION: DyecoTrode Super Cast is characterized by a smooth arc and virtually spatter-free weld deposits. The as-deposit structure is essentially a nickel-iron matrix with a very fine dispersion of graphite nodules for improved crack resistance.
APPLICATIONS: Compressor casings, bell housings, differential cases, jacketed castings (engine blocks) cast iron automotive dies, etc. For difficult applications call your Dyeco Office for more information & customer-engineered solutions.
SUPER CAST PREPARATION:
Prepare the joint to be welded by first degreasing followed by grinding or pneumatic chipping. For arc-gouging preparation use DyecoTrode XO-THERM. When grinding it is important NOT to cause coloring in the casting. This indicates overheating and possible hard-spotting. A nominal preheat of 150º to 225ºF is recommended for heavy castings with thick cross-sections. For broken sections allow a root opening of 1/8” to 3/16 for full penetration welds.
SUPER CAST WELDING TECHNIQUE:
Select the most suitable diameter based on part thickness, mass, and area to be repaired. Using the amperage range shown in the Technical Information Table, for optimum results. Maintain a reasonably short arc-length while holding the electrode nearly vertical to the work-piece. Deposit short runs not more than 2” to 3” long. De-slag and wire brush between multi-passes and over-lapping weld deposits. Peen moderately to reduce contraction stresses. Allow part to cool in still air after welding.
