SMAW
The chemical compositions of carbon, silicon, sulfur, aluminum, and nickel satisfy the strength and characteristics of Alloy 112 coated electrodes. The weld of Alloy 112 rods is soft enough to be milled, drilled, tapped, or machined, but it still provides significantly more strength than the base metal, and the color matches the cast iron. Coated electrodes are known for providing excellent surfacing and welding of gray cast iron, malleable cast iron, and malleable cast iron itself or for joining these cast iron types to mild steel
Product Detail
- Weld nickel-chromium-molybdenum alloys.
- Used extensively in overlay cladding where a similar chemical composition is required on the clad side.
- Dissimilar joints between nickel-chromium-molybdenum alloys to stainless steels, carbon or low alloy steels.
- These electrodes are used in applications where the temperature ranges from cryogenic up to 1800°F ( 982°C).
