The consumables are suitable for surfacing and cladding provided the need for an appropriate buttering layer is addressed, normally either alloy 400 or pure nickel. The 70/30 consumables are suitable for welding 70/30, 80/20 and 90/10 base materials. The 70/30 consumables match the 70/30 base materials for strength and color and overmatch the 90/10 alloys for strength. Applications include **offshore construction, desalination plant, evaporators, condensers etc., in salt and sea water processing systems**. Preheating not normally required, maximum interpass temperature 150°C and no PWHT. Contamination of the weld zone with foreign material, particularly any source of lead, tin or zinc must be scrupulously avoided to prevent weld metal cracking.
