Elektrodi OK53.70 2,5

A low-hydrogen AC/DC electrode for the one-sided welding of pipes and general structures. The root penetration is good, leaving a flat bead with easily removable slag. The stable arc and the well-balanced slag system make the electrode easy to weld in all positions. Suitable for welding transmission pipelines made from pipe steels up to API 5LX56. It is also suitable for welding the root in higher strength pipes, API 5LX60, 5LX65, 5LX70. SFA/AWS A5.1; E7016-1; EN ISO 2560-A; E42 5 B 12 H5; GOST 9467-75; E50A.
