摘　　要：阐述了在大功率的光纤激光器下,使用自发激光焊或激光复合弧焊,采用6 mm、8 mm和10 mm厚度及T型接头结构,将低合金钢S355和AH36进行焊接的过程。目的是通过方法性地研究激光功率影响、焊接速度、相对于表面的射束校准、气隙、焦点位置及流程顺序(用于激光复合弧焊),来理解影响圆角和焊缝结构尺寸的因素,并在参数优化之后,在所有厚度中获得焊接质量等级B级。The processes of spontaneous laser welding and laser hybrid arc welding for low alloy steels S355 and AH36 by high-power fiber laser respectively with 6 mm, 8 mm and 10 mm thickness and T type welding heads are introduced in this paper. Its purpose is to understand the influence factors of fillets and weld structure sizes by studying the laser power effect, welding speed, beam alignment relative to surface, air gap, focal position and sequence（for laser hybrid arc welding）,and obtain welding quality grade B in all thickness after parameter optimization.
