Welding Electrode

ROYAL – MONEL (E Ni Cu – 7)

AWS : A / SFA 5.11, E Ni Cu - 7 EN ISO 1472 A E Ni 4060

Applications

It is used for welding the clab side of joints in steel clad with a Nickel – Copper alloy and for surfacing steel with Nickel –
Copper alloy weld metal to obtain a corrosion resistant surface. It is also used for fabrication and welding for the Nickel –Copper base material like ASTM – B127, B 163, B 164, and B 165 all of which have UNS No. 4400.

Notes On Usage

1) Chip off base metal completely at the repairing part .
2) There is possiblity that cracks spreads or makes holes at both ends of repairing part .
3) Keep the weld metal length less than 50 mm (2 inch ) to disperse welding heat- adopt back steping stone or symmetry method by turns.
4) The preheat temprature vary in accordance with te size ,king and
shape of the base metal150°C is
appropriate in general .
