Excellent mechanical properties of the deposited metal and increased corrosion resistance in aggressive environments at temperatures up to 450 °С. High welding-technological properties, low spatter loss, almost self-separating slag crust, and the seam flowing with a smooth transition to the base metal are noted.
PURPOSE AND FIELD OF APPLICATION
Rutile coated electrodes CL-11 Plasma designed for welding austenitic corrosion-resistant steels AISI321, AISI347, 08X18H12T, 08X18H12B, 03H18N11, 06H18N11, 08H18N12B, 08H18N10, 12X18H10T, AISI 321, AISI 304, AISI 347, etc., that work in aggressive environment at temperatures up to 450 ° C. They are used for welding pressure vessels, pipelines, parts of equipment in the food and petrochemical industry, power machine-building, and power engineering.
APPLICATION CONDITIONS
Electrodes used for welding in all spatial positions on a direct current of reverse polarity and alternating current from transformer of open-circuit voltage not less than 65 V. It is recommended to weld in the lower position on medium currents. Welding must be performed in a short arc, without transverse oscillations.
REDRYING BEFORE WELDING
At the normal storage conditions, redrying is not required. In case of moisture the redrying is made at 350-370°С for 60 min. 3 times max.
