Elektroder

CuNi-alloyed LMA all-current electrode which produces a weld metal with good corrosion resistance against salt water and flue gases, and was used for weather-resistant steels and for structural steel in ships. The weld metal has excellent mechanical properties. OK 73.08 is particularly suitable for welding armor steel in icebreakers and other ships operating in conditions where protective paint wears away. Intended for e.g. CORTEN, Domex 350W, UHBCCP etc. The good mechanical strength properties also make it suitable for welding general high-strength steels as well as ordinary and high-strength ship steels of A, D and E quality.

CrMo alloy electrode for welding hardenable steels of the type 0.25C1Cr0.2Mo. As a rule, welding should be carried out at a working temperature of 200-300°C. Recommendations for heat treatment of the welding material from OK 78.16 are the same as for the base material. The weld metal is also suitable for vam hardening. Welding of high-strength steels with OK 78.16 should be carried out with a preheating temperature of at least 200°C. DC+
