The influence of thermal conditions and some technological methods (intermediate inserts of monolithic metal, nanomodifying additives) on the quality of the permanent joint of porous titanium obtained by laser welding is studied experimentally. It has been established that, to obtain a high-quality defect-free weld, it is necessary to use an intermediate insert made of compact metal placed butt-to-butt between the ends of the butt-welded plates. The position of the focal spot should be set at a depth equal to the thickness of the plate, i.e. on its bottom surface. The use of modifying additives based on titanium nitride increases the dispersion and uniformity of the weld structure and the heat-affected zone, and this positively affects the mechanical characteristics of the metal.
