Abstract

Numerical simulation of unsteady processes during laser butt welding of a plate made of porous titanium and a monolithic (non-porous) titanium plate is performed. The influence of the laser beam position relative to the welded surfaces on the quality of the resulting joint and the geometric seam characteristics is considered. The calculated welded joints parameters of porous and monolithic plates are in satisfactory agreement with the physical experiments results.
