Electrodes Monolith M-318 provide metal seam resistant to intercrystalline corrosion. Characterized by high welding-technological properties: stable arc burning, easy slag removal, good formation of seam with a smooth transition to the base metal.

PURPOSE AND FIELD OF APPLICATION

Rutile coated electrodes Monolith M-318 are designed for welding corrosion-resistant austenitic Cr-Ni-Mo steels stabilized with niobium of 08Х16Н13М2В, 03Х17Н14М2, 03Х17Н14М3, AISI 316Nb, AISI 316, AISI 318 types, etc., for parts working under temperature up to 400 C. Electrodes are used for welding of tanks, pipes and equipment for chemical, textile, paper industries, in environments where acidic, alkaline and saline solutions are found, as well as for structures that operate in seawater.

APPLICATION CONDITIONS

Electrodes are used for welding in all the spatial positions, except for the downward one. It is recommended to perform welding at maximum possible speed without transverse oscillations of electrode.

REDRYING BEFORE WELDING 

At normal storage conditions, the redrying is not required. In case of moisture, redrying is required at 350-370°С for 60 min.., 3 times max.
