What are the advantages of 　　inverter DC spot welding machine ?

　　1. First, the current range for forming a stable nugget is wide. Due to the output of DC welding current, the thermal efficiency is high. Because there is no current spike in DC, it is not easy to produce spatter, which makes the allowable current upper limit larger. Under the condition of the same effective value of welding current, the dynamic resistance of the workpiece during DC welding is larger than that during AC welding, so the solder joints generate more heat. , The nugget grows faster, so that the lower limit of the allowable current is smaller, that is, the current range for forming a stable nugget is wide when DC output.

　　2. Long electrode life. Because there is no current spike during DC welding, the current is not subject to mechanical impact, which is conducive to the extension of electrode life.

　　3. Small electromagnetic influence. When the magnetic welding parts and fixtures are placed in the working arm of the AC spot welding machine, it will have a great impact on the welding current, but it will not affect the welding current during inverter DC welding. 4. DC welding has no AC "skin" effect. Along the axial 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. Dissimilar metals can be spot welded widely. The direct current has a "clustering" function, the current is relatively concentrated, the shunt is small, the thermal efficiency is high, and low flow welding can be used. Therefore, intermediate frequency inverter spot welding has the superior characteristics of welding coated steel plates, aluminum, and combined welding of different thermally conductive materials.
