摘　　要：通过改变冷轧激光焊机的焊接工艺,进行生产高强钢冷轧钢带的对比研究,得出生产冷轧高强钢最适宜的激光焊接工艺。试验证明使用具有前后预热系统的激光焊机,并选择合理的焊接工艺,使得高强钢的焊缝具有很好的韧性,轧机断带率也大大降低。Through varying the welding process of cold rolling laser welding machine,the comparative study on the production of cold-rolled high strength steel was conducted,and the optimum laser welding process of cold-rolled high strength steel was obtained. Tests results proved that using laser welding machine with before and after preheating system and choosing the appropriate welding process,the weld of high strength steel had high tenacity and the rate of strip breakage of cold-rolled machine decreased.
