Acor Ni S
Pure nickel electrode
Description & applications
Basic coated electrode with a Nickel deposit containing 1-2%Ti designated for butt welding of pure Nickel (alloy 200) and surfacing of Nickel-copper, Copper-Nickel and Copper-Nickel plated steels. Also recommended for dissimilar joining like steels to Nickel-Copper or steel / Copper to Copper-Nickel.
Excellent resistance to NaOH up to 400°C.
Main applications: Construction of equipment for the chemical industry and petrochemical industry, food stuff industry. For caustic soda production as well as for soap and detergents.

Welding Instructions
Redrying 1 h at 250-300°C. Joints to weld must be clean, exempt from grease, cracks. Guide electrodes with a slight declination (10-20°) inclined in direction of travel), weld with a short arc and apply the stringer bead technique (weaving max. 2 times core wire diameter). To improve degassing of the deposit, adopt a low welding speed.
