prior cleaning of weld zone of dirt, rust, oil before welding is required;
to avoid staining, application of more than 2 layers on steel parts and more than 1 layer on cast iron parts is not recommended;
in case of extreme worn-out of the part, application of buffer layers with other electrodes is recommended, the choice of which depends on the composition of the base metal;
transverse microcracks should not be considered as defect, but an indicator of high deposited metal hardness;
to ensure better crack resistance of the deposited metal, preheating of the base metal is recommended.
Special properties
HS-Fe15 electrodes are primarily intended for welding of fast-wearing surfaces that work in abrasive wear conditions, as well as where increased hardness is required;
high hardness of the metal deposited by these electrodes is achieved due to introduction of special alloying elements into the coating.
HS-Fe15 electrodes are designed for welding of machinery parts operating under conditions of mainly abrasive wear with moderate impact loads. They are used for welding of the crushing jaws, bandages of roller crushers, beaters of hammer crushers and mills for grinding coal, bucket teeth of a rotary excavator, cutting teeth, working parts of briquette presses, trailing leaves, smoke pump blades. Deposit obtained with these electrodes has excellent wear-resistant performance characteristics and strength indicators.
Electrodes MONOLITH RC are differed from similar products of other manufacturers by a value and intensity of welding aerosol evolution and manganese formation during the welding process. This was achieved by selecting the high-quality raw materials and high-level control of technological processes in electrodes manufacture. The E.O. Paton Electric Welding Institute of the NAS Ukraine and Institution of Medicine Labour of the AMS Ukraine confirmed that manganese precipitation was reduced for more than 30%, the evolution of harmful elements in welding aerosol was reduced for more than 28%.
Electrodes MONOLITH RC are characterized by an easy primary and secondary arc exciting, soft and stable arc burning, provide low spatter loss, uniform melting of the coating, excellent weld metal formation, easy slag crust removal.
Electrodes allow welding at the lowest currents. For the small-diameter electrodes, the welding can be performed from power sources, connected to conventional mains.
Easy use of electrodes gives an opportunity to perform welding by a beginning welder.
Welding in hard-to-reach places. Feasibility of electrode bending without the coating damage.
It is possible to perform welding on oxidized, greased and painted surfaces.
the permissible moisture content in the coating before use is not more than 0.4 %;
if the electrode coating is moistened above normal, dry for 60 minutes at 250±20°С (482±68°F)
