Two can welding be changed into a pair of welding machines?
Two welding machine can not be changed to welding machine
May not。Two welding is welding. The butt welding belongs to the resistance welding series.Two, welding is a flat hard external characteristics, relatively high welding voltage, in order to facilitate welding wire melting. The resistance butt welding requires low voltage, high current and short time compression, so that the contact point is partly melted and the nugget is formed.Different working principle. Cannot change.
Two, welding is welding, welding machine output is flat, hard external characteristics. A relatively high voltage is required to melt the wire to achieve welding purposes. Current is DC output.The butt welding machine belongs to the series of resistance welding. The electrode plays the role of pressing the workpiece and conducting electricity. It is not used as the melting electrode. Therefore, a relatively low voltage (usually only a few volts) is required to prevent electrode melting from sticking to the substrate. Relatively short time (millisecond) and relatively large welding current (3000 amperes to tens of thousands of Amperes) make electrodes less burn out. At present, DN series power frequency welding machine is mainly used.The work principle is different and cannot be changed.
