Effect of technological parameters on the process of diffusion welding of titanium

Abstract

Results of investigation into the effect of welding conditions and microstructure of welded components on the course of the welding process and the quality of diffusion-welded joints in specimens of VT14 titanium alloy are presented. The results show that, depending on the combination of the microstructure of the components and the welding temperature, the formation of the welded joint is controlled by the activation of the contact surfaces and by the development of the stage of volume interaction or physical contact.
