When you use the medium frequency inverter spot welding machine, if the welding parts will splash, the main reasons are as follows:
1, first of all, in the welding workpiece when the pressure is too small, welding cylinder servo poor, as well as the machine itself poor strength, when the welding pressure is too small, coupled with the cylinder of the poor servo, so that it is possible in the welding deformation speed can not keep up with the splash, serious times will hit the surface. If the spot welding machine itself is not strong enough, the mechanical deformation between the two electrodes will also lead to the dislocation of the upper and lower electrodes, resulting in splash. To solve these problems, Agera engineers will first adjust the appropriate pressure according to the welding requirements of the workpiece, keep the upper and lower electrodes flat and vertical, check the strength between the two electrode arms when the two electrodes are pressed, whether there is deformation, to exclude these factors, so our medium frequency inverter spot welding machine can avoid the production of sputtering!
2, in addition, the parameter adjustment of the medium frequency inverter spot welding machine, the precompression time is too short, the electrode head just touches the workpiece and starts to discharge, the welding current setting is too large and the welding time setting is too long, will produce splash, so the welding process is very important, Agera engineers will adjust the parameters according to the material and welding requirements of the welding product, set the corresponding welding parameters. So you can avoid splashing.
3, in addition, the choice of electrode head of the medium frequency inverter spot welding machine, for example, when spot-welding galvanized plate, because the zinc layer on the surface of the galvanized plate has a low melting point, it is very high temperature, and after high temperature, it becomes a bras-like alloy component, which is stuck on the surface of the electrode, resulting in poor electrode conduction, welding is not strong, it will increase the current, it will produce splash, so if you buy our spot welding machine, Our engineers will recommend that you choose aluminum oxide copper, its characteristics of oxidation temperature of up to 900 degrees, compared with chromium pick copper oxidation temperature of about 550 degrees, higher than nearly 350 degrees, can greatly reduce the number of electrode repair mold, improve production efficiency, welding galvanized sheet, while we generally use two sections of welding current, the first section of small current to weld the zinc layer destroyed. The second section of the current is slightly larger to achieve the welding effect, which can also avoid the occurrence of welding spatter.
After reading the above three points, you should know what is the reason? The function of the welding machine is important, but the professional degree of the pre-sales and after-sales engineers is also very important!
