1.By adjusting the ratio of optical path and process parameters, the thin copper bar can be welded without spatter (upper copper sheet <1mm);
2.Equipped with power monitoring module can monitor the stability of laser output in real time;
3.Equipped with WDD system, the welding quality of each weld can be monitored online to avoid batch defects caused by failures;
4.The welding penetration depth is stable and high, and the fluctuation of penetration depth is less than ±0.1mm;
5.IGBT welding of thick copper bar can be realized (2+4mm / 3+3mm).
