Use & Application
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. 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.
