Descripción y aplicaciones
• Metal cored wire for semi-automatic gas shielded metal arc welding
• Designed for welding grey, malleable, nodular and phosphorous cast iron
• Welding of highly restrained or thick walled pieces
• Preheat is not necessary. Heat input is low which favours limited H.A.Z.
APPLICATIONS
• Joining and surfacing highly restrained spheroidal graphite cast iron, grey cast iron and malleable cast iron pieces. Also used for dissimilar welds between cast iron and steel.
Casings for pumps and valves, frames, machining errors on castings, crushers, gear housing etc.
Examples
Lamellar grey cast irons - DIN 1691 - GG 10 to GG 40
Malleable cast irons - DIN 1692 - GTS 35 to GTS 64, GTW 35 to GTW 65
Nodular cast irons - DIN 1693 - GGG 40 to GGG 70
