Résumé: eksperyans soudure lazè plis sifas modification soudure de 1.5 milimètTi-6Al-4V Titàn alyaj was carried out, and the microstructure and static properties of the joint were observed. The results show that due to the influence of different welding thermal cycles, The structure area of laser welding plus surface modification welding joint can be divided into a base metal area, heat affected area, equiaxed crystal area at the bottom of weld, and columnar crystal area at the top of the weld, there is widmanstatten structure in the weld structure, With the increase of the distance from the fusion line, the microstructure of the heat-affected zone increases ' The volume fraction decreased gradually.

Pwopriyete mekanik jwenti a montre ke fòs rupture ak fòs taye yo ekivalan a metal debaz la, ak ang minimòm koube a se 35 degre, ki endike ke jwenti a ka aplike nan jeni.
