摘要
基于不锈钢薄板非熔透CO2激光搭接焊和光纤激光搭接焊获得的实际焊缝形状,采用表面高斯+柱状体复合热源模型,得到热源比例系数分别为0.85和0.70。对其余4个热源描述参数,包括高斯热源半径和深度、柱状热源半径和深度进行正确设置,就可以获得不同焊接功率和焊接速度下,搭接焊缝形状表征参量(表面缝宽、中间熔宽和熔深)的变化规律。模拟结果与试验结果符合很好。
Abstract
Based on the actual weld shape from stainless steel sheets with non-penetration CO2 laser lap welding and fiber laser lap welding, by taking the Gaussian-plane+cylinder-body composite heat source model, the obtained heat source proportionality coefficients are 0.85 and 0.70, respectively. By correctly setting the other four parameters for describing heat source, including the radius and the depth of Gaussian heat source, and the radius and the depth of cylinder heat source, the change laws of weld shape characterization parameters (surface seam width, middle weld width and weld penetration) of lap welds can be obtained under different welding powers and welding speeds. The simulation results are well consistent with the experimental results.
