Abranel 70/30
Basic coated NiCu type electrode
Description & applications
Basic coated electrode with a Monel* type Nickel-Copper deposit designated for butt welding and surfacing of Nickel-copper, Copper-Nickel and Copper-Nickel plated steels. Also recommended for dissimilar joining like steels to Nickel-Copper or steel to Copper / Copper-Nickel.
Excellent resistance to stress corrosion in Cl- containing environments.
Main applications: Construction of equipment for the chemical industry and petrochemical industry, naval constructions and installations for sea water desalination.
Note:”Monel” is a registered trade name of Inco Alloys.

Welding Instructions
Redrying 2 h at 250°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 prevent a high heat input by applying the stringer bead technique (weaving max. 2 times core wire diameter).
