Welding electrodes M-347
product.uv
- welding is carried out in all spatial positions on 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 transverse oscillations
product.sv
- excellent mechanical properties of the deposited metal and increased corrosion resistance in aggressive environments at temperatures up to 450 °C
- high resistance against intercrystalline corrosion
- increased resistance of the deposited metal to the formation of hot cracks
- high welding and technological properties, low spattering, practically self-separation of the slag crust and the formation of a seam with a smooth transition to the base metal were noted
- surfacing coefficient: 0.18...0.19 g/A•min
- consumption of electrodes per 1 kg of deposited metal: 1.5...1.6 kg
Electrodes M-347 with rutile coating are intended for welding austenitic corrosion-resistant steels 08Х18Н12Т, 08Х18Н12Б, 03Х18Н11, 06Х18Н11, 08Х18Н12Б, 08Х18Н10, 12Х18Н10Т, AISI304, AISI347 etc., working in aggressive environments at temperatures up to 450°C. They are used for welding pressure vessels, pipelines, equipment parts in the food and petrochemical industry, power engineering, energy.
