1. First, the current range of stable nugget is wide. Due to the output of DC welding current, high thermal efficiency. Because DC has no current spike and is not easy to generate spatter, the allowable current upper limit is relatively large. Under the condition of the same effective value of welding current, the dynamic resistance value of the workpiece during DC welding is larger than that during AC welding. Therefore, the heat generation of the solder joint is large and the nugget grows faster, which makes the allowable current lower limit smaller, I .e. the current range for forming a stable nugget during DC output is wide.
2. Long electrode life. DC welding due to no current spike, so that the current is not subject to mechanical impact, is conducive to the extension of electrode life.
3, electromagnetic influence is small. When magnetic weldments and clamps are placed in the working arm of AC spot welding machine, the welding current is greatly affected, but there is no such shadow in inverter DC welding. 4. DC welding has no AC "skin" effect. Along the axis direction of the upper and lower electrodes, the welding current distribution on different weldment thicknesses is relatively uniform, so the heating is relatively uniform.
5, can widely spot weld dissimilar metals. DC current has a "cluster" effect, the current is relatively concentrated, the shunt is small, the thermal efficiency is high, and can be welded with low flow. Therefore, intermediate frequency inverter spot welding has the advantages of welding coated steel plate, aluminum and combined welding of different thermal conductive materials.
