摘　　要：为了拓展半导体激光器在激光加工领域的应用范围,使其能够应用到厚板金属材料的焊接中,采用了Laserline公司研制的LDF4000-40光纤耦合半导体激光焊接系统,研究了其厚板SUS304奥氏体不锈钢的焊接性能。实验结果表明,其厚板SUS304奥氏体不锈钢焊接过程中完全能够形成匙孔效应,具有较强的穿透能力;相比于同等工作条件下的光纤激光,其焊接熔深有所减小,而焊接熔宽有所增加;焊缝成型及焊接过程稳定性要优于光纤激光,飞溅量明显小于光纤激光。由此证实了光纤耦合半导体激光器完全可以用于厚板金属材料的焊接。In order to expand the applied range of diode laser in laser processing field, and to apply diode laser to the thick plate welding of metal materials, the fiber coupled diode laser of LDF4000-40 that developed by the Laserline company is adopted to investigate the welding performance of the thick SUS304 austenitic stainless steel. Experimental results show that the keyhole can be formed, proving the ability of strong penetration. Compared to the fiber laser welding under the same welding conditions, the weld penetration depth decreases and bead width increases slightly; weld forming and welding process stability is better, and spatter is significantly smaller. The results confirm that the fiber coupled diode laser can be used for the thick plate welding of metal materials.
