摘要
综合考虑熔滴与熔池相互作用的物理过程 ,建立了描述熔池表面变形的数学模型和熔滴热焓量在熔池内部的分布模型 .应用数值模拟技术分析了焊接工艺参数对熔池表面形状、熔滴热焓量分布区域、焊缝成形的相互影响规律 。
By considering the interactional physical process of droplet and weldpool, a mathematical model of weldpool surface deformation and a distribution model of droplet heat content inside weldpool are established. Numerical simulation technique is employed to analyze the correlation of welding parameters, distribution volume of droplet heat content and welding seam figuration. The experiments show that the simulation results are in agreement with the measured ones.
