采用5kW高功率横流CO2激光器加工系统对A3低碳厚钢板进行焊接试验,研究了工艺参数对激光深熔焊的焊缝的影响,并进一步进行了优化试验,对试样进行了拉伸试验、金相分析和显微硬度分析。
A 5kW high-power cross-flow CO2 laser processing system was used to test the welding of A3 low carbon steel plate. The influence of process parameters on the weld of laser deep penetration welding was studied. The optimal test was further carried out, Metallographic analysis and microhardness analysis.
