Abstract

The nonstationary processes that occur during laser butt welding of a plate made of porous titanium and a plate of monolithic (nonporous) titanium are numerically simulated. The influence of the position of a laser beam relative to the surfaces to be welded on the quality of the resulting joint and the geometric characteristics of the weld is considered. The calculated parameters of the welded joints of the porous and monolithic plates are in satisfactory agreement with the results of physical experiments.

多孔钛板和整体钛板激光焊接的数值模拟

摘要

对多孔钛板和整体（无孔）钛板激光对接焊接过程中发生的非平稳过程进行了数值模拟。考虑激光束相对于待焊接表面的位置对所得接头质量和焊缝几何特征的影响。多孔板和整体板焊接接头的计算参数与物理实验结果吻合较好。
