Professional distribution Supply [SD-3502CY] Japan Sansha (Thyristor) CO2 gas welding

A) arc voltage and welding current transition arc voltage is shorted key parameters, short transition is powered by low voltage. Arc voltage and welding current matches, you can get small spatter, weld good steady welding process. Φ1.2 the general parameters for the voltage 19 V; current 120 to 135. 2) With the welding speed welding speed increases, the weld width, high penetration and I are reduced. Welding speed is too high, prone to biting edges and defects such as lack of penetration, while gas starts to deteriorate, easy to produce pores. Welding speed is too low, easy to burn, coarse microstructure defects, and deformation increases production efficiency. Therefore, should be based on the welding speed production practices make the right choice. Usually no more than semi-automatic welding speed 0.5m/min, automatic welding speed of not more than 1.5m/min. 3) purity of the gas flow and gas flow rate is too small, insufficient stiffness of protective gas, welding defects such as porosity prone; gas flow is too large, not only the waste gases, and enhanced oxidation, will form a layer on the surface of the weld Dark gray scale, so that the weld quality. To ensure the welding area from air pollution, when the welding current is large or welding speed, longer length of wire out and outdoor welding, gas flow rate should be increased. Typically filaments welding, gas flow between the 15 ~ 25L/min. CO2 gas purity not less than 99.5%. Meanwhile, when the pressure inside the cylinder is less than 1Mpa, they should stop using, avoid porosity. This is because the cylinder pressure is reduced, the dissolved CO2 in the liquid also increases the amount of vaporization of water, so the water vapor mixed with CO2 gas more. 4) transition due to short length of wire out are made of fine wire, so the length of wire out resistance heat generated on the great influence. Extended length increases, increased heat resistance on the wire, wire melting speed, productivity increased. However, when the projecting length is too large, the wire section is made prone to overheating fuse, splash serious instability of the welding process. While projecting increases, the nozzle and the distance between the weldment also increases, so gas effect worse. However, inevitably reduce the projecting length of the small nozzle and the distance between weldments, metal splash easily clog the nozzles. Suitable wire protruding length should be 10 to 12 times the diameter of the filament 8 ~ 15mm when welding is appropriate.

Welding process and are conducive to mechanization and automation, in particular spatial location mechanized welding. 2) arc shielding gas compression heat concentrated, welding speed, the pool is small, narrow heat-affected zone, weldment after deformation, cracking performance, especially for sheet metal welding. 3) with argon, helium and other inert gas welding chemically more reactive metals and alloys, and has good welding quality. 4) In the outdoor work, you must set up wind shield to welding, arc light radiation is strong, welding equipment is more complex.
