摘要
激光切割后,金属薄壁类零件的材料基体与下方的支撑板易产生粘连,严重影响切割质量.采用光纤激光对304不锈钢和GH605高温合金薄板进行切割实验,分析了激光切割不同材料发生粘连的机理.采用单因素试验法分析了激光切割工艺参数对热影响区及毛刺堆积量的影响规律.加工结果显示,在加入微连工艺的前提下,激光功率为165 W,切割速度为5 m/min,辅助气体压力为1.2 MPa时,切缝边缘光滑、无变形及残留黏附现象.
Abstract
After laser cutting,the material substrates of thin wall metal components and the sup-port plates below were prone to adhesion,which seriously affected the cutting quality.Fiber laser cut-ting experiments were conducted on 304 stainless steel and GH605 high temperature alloy thin plates,and the formation mechanism of the adhesion in laser cutting of different materials was analyzed.The single factor experimental method was used to analyze the influences of laser cutting process parame-ters on the HAZ and burr accumulation.The processing results show that with the addition of a mi-cro-connection process,when the laser power is as 165 W,the cutting speed is as 5 m/min,and the auxiliary gas pressure is as 1.2 MPa,the cut edges are smooth and without deformation and residual adhesion.
