Abranel 9Ni
Basic coated high strength Ni-base electrode for AC
Description & applications
Basic coated electrode with approx. 160% recovery. The electrode is especially designed to weld with alternating current to avoid magnetic arc blow.Mainly used for construction and repair welding of high strength cold-tough 3; 5 and 9% Ni-steels used for transportation and storage tanks of liquid natural gas.

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, weld with a short arc and prevent a high heat input by applying the stringer bead technique ( weaving max. 2 times core wire diameter).
