Welding electrodes Monolith M-347

AWS A5.4: E 347-16

EN ISO 3581-А-E 19 9 Nb R 1 2

welding is carried out in all spatial positions with direct current of reverse polarity or alternating current from a transformer with an open-circuit voltage of 50±5 V
welding must be performed with a short arc without lateral oscillations

Special properties

excellent mechanical properties of the deposited metal and increased corrosion resistance in aggressive environments at temperatures up to 450 °С
high welding and technological properties, small spattering, easy separation of slag crust and formation of a seam with a smooth transition to the base metal are noted
surfacing coefficient: 0,15…0,19 g/A•min
consumption of electrodes per 1 kg of deposited metal: 1,3…1,6 кг

Electrodes Monolith M-347 are designed for welding austenite of corrosion-resistant steels 08Х18Н12Т, 08Х18Н12Б, 03Х18Н11, 06Х18Н11, 08Х18Н12B, 08Х18Н10, 12Х18Н10Т, AISI304, AISI347, etc., operating in aggressive environments at temperatures up to 450°C. They are used for welding containers operating under pressure gas, pipelines, food and petrochemical equipment parts industry, power engineering, energy.
