Carbon steel, with two, welding current, voltage, welding speed, wire diameter, thank you
The following welding parameters are usually used: 100-200A, 18-25V, 1.2-1.6mm
The following welding parameters are usually used: 100-200A, 18-25V, 1.2-1.6mm
Various parameters of CO2 gas shielded arc welding(1) wire diameter;The diameter of welding wire is usually chosen according to the thickness of welding piece, the position and efficiency of welding application. When welding in all position welding of sheet or plate, the welding wire below 1.6mm (called wire CO2 gas shielded welding) is adopted.(2) the welding current depends mainly on the wire feeding speed. The faster the wire feed, the greater the welding current. The welding current has the greatest influence on the weld penetration. When the welding current is 60~250A, that is, short circuiting transition welding, the weld penetration is generally 1mm~2mm; only when 300A or more, the melt body is obviously increased.(3) when the arc voltage is short circuiting, the arc voltage can be calculated by the following formula: U=0.04I+16 + 2 (V)At this point, welding current is generally below 200A, welding current and arc voltage of the best fit in table 2. When the current is above 200A, the formula for calculating the arc voltage is as follows. U=0.04I+20 + 2 (V)(4) welding speedIn semi-automatic welding, the welding speed of skilled welders is 18m/h~36m/h, and the speed of welding can be as high as 150m/h at automatic welding.(5) the extending length of welding wire;The extending length of general wire is about 10 times of the diameter of wire, and increases with the increase of welding current.(6) the normal welding gas flow, 200A has been under the sheet metal welding and CO2 welding flux is more than 10L/min~25L/min.200A, the flow of CO2 for large specification of 15L/min~25L/min. thick wire automatic welding for 25L/min~50L/min.
