Electrodes OZL-6 Plasma are characterized by good welding and technological properties: low spatter loss, easy separation of slag crust, stable arc burning and excellent seam quality. When welding heterogeneous steels, high resistance to cracks is ensured, and high resistance to intercrystallite corrosion up to 300 ° C is noted. In addition, when welding heat-resistant stainless steel provides high resistance to the formation of scales to 1000°С.

 

PURPOSE AND FIELD OF APPLICATION 

Electrodes OZL-6 Plasma (M-309L) are designed for welding heterogeneous steels (austenitic and carbon), austenitic stainless steels of type 08Х18Н10, 03Х18Н11, AISI 304, AISI 304L, etc., where the use temperatures do not exceed 300°C, as well as for welding of heat-resistant Stainless steels of type AISI 309, AISI 309S and similar in chemical composition 20X23H13, 08X23H13. They are used for surfacing of the transition layer on heat-resistant chromium-molybdenum steel of perlite class and for placement of ferrite-perlite, low and medium doped bases and for application of buffer layers before surfacing. These electrodes are suitable for welding tanks and containers (used to store a large variety of liquids and dry substances), industrial equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries.

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 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.
