G-TECH 413

Suitable for surfacing and cladding, provided there is an appropriate buttering layer, typically either alloy 400 or pure nickel. The 70/30 consumables are applicable for welding 70/30, 80/20, and 90/10 base materials. Matching the strength and color of the 70/30 base materials, they also exhibit overmatching strength compared to the 90/10 alloys. Applications include offshore construction, desalination plants, evaporators, condensers, etc., in salt and seawater processing systems. Preheating is not usually required, with a maximum interpass temperature of 150°C and no post-weld heat treatment (PWHT). It's crucial to meticulously avoid any contamination of the weld zone with foreign materials, especially sources of lead, tin, or zinc, to prevent weld metal cracking.
