Welding electrodes Monolith M-308L
Terms of use
- applied when welding in all spatial positions, except vertical from top to bottom
- welding is recommended to be performed at the maximum possible speed without transverse oscillations of the electrode
Special properties
- characterized by high welding and technological properties, low spatter, stable arc burning, easy separation of the slag crust and excellent seam quality
- excellent corrosion resistance in oxidizing environments and high resistance to intercrystalline corrosion
surfacing coefficient: 0,16…0,18 g/A•min - consumption of electrodes per 1 kg of deposited metal: 1,4…1,6 кг
Electrodes of the Monolith M-308L brand are intended for welding austenitic stainless steels of the type 03Х18Н10, 08Х18Н10Т, AISI 304L, AISI 321, AISI 347, etc., not in the working temperature range above 450°C. These electrodes are suitable for welding equipment, stainless steel tanks, cisterns and pipes for use in food, textile, oil refining, drinking, paper and pharmaceutical industry, as well as in the automotive industry and general mechanical engineering.
