研究了二氧化碳激光焊接工艺条件对锆－４合金接头质量的影响。结果表明，在适宜的焊接工艺条件下，可以获得焊缝成形系数大，力学性能接近于母材的焊接接头；与氩弧焊相比，其接头质量显著地优于氩弧焊
The effects of CO2 laser welding conditions on the quality of zirconium-4 alloy joints were studied. The results show that under appropriate welding conditions, the weld joint with large weld-forming coefficient and mechanical properties close to the base metal can be obtained. Compared with argon arc welding, the joint quality is significantly better than that of argon arc welding
