摘要:
以304不锈钢薄板为研究对象,从流体力学与传热过程的角度建立了激光直缝焊瞬态行为的物理模型,并对其整个过程的温度和应力场变化进行了可视化分析.结果表明:在激光焊功率为3 000 W情况下,当焊接速度为50 mm·s-1时,峰值温度最高达2 500 K以上,起焊距离短,只有0.81 mm.
Abstract:
Taking 304 stainless steel sheet as the research object,the physical model of transient behavior of laser longitudinal welding is established from the perspective of fluid mechanics and heat transfer process,and the change of temperature and stress field in the whole process is visualized.The results show that when the laser welding is 3 000 W power,the peak temperature is up to 2 500 K when the welding speed is 50 mm·s-1,and the welding distance is the shortest,only 0.81 mm.
