摘要
利用CO2激光对汽车车身用高强度钢板进行了大量的焊接试验,并对焊缝组织进行了相关的机械性能试验,研究了激光焊接工艺参数对接头强度的影响规律.
Based on many experiments of CO2 laser welding of zinc coated high strength steel to vehicle body. Joint microstructure and stressstrain curve of specimen are acquired. Influence of laser welding technological parameters on joint strength was studied.
