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.
