利用自行设计的填丝激光焊系统，研究了大功率ＣＯ_２激光填丝焊接工艺参数对ＨＡＺ尺寸及焊缝成形的影响。实验确定了最佳的送丝角度范围，发现填丝激光焊的焊缝形状近似呈“Ｘ”形。
The effect of welding process parameters on HAZ size and weld formation of high power CO 2 laser welding wire was studied by using self-designed wire-bonding laser welding system. The optimum wire feeding angle range was determined experimentally and it was found that the shape of the weld of the filler wire laser welding was approximately “X”.
