DISSIMILAR TI ALLOYS WELDING FOR THE AUTOMOTIVE AND AVIATION SECTOR

Titanium alloys have an excellent strength-to-weight ratio. Tit alloys are almost as strong as steel but are much lighter. This translates into reduced mass in means of transportation (e.g., aircraft, F1 cars, electric vehicles, and motorcycles), which translates into better fuel efficiency, speed. Titanium can withstand very high temperatures without losing its mechanical properties. As a result, it has found applications in exhaust systems, hydraulic lines, fuel systems, and structural elements exposed to extreme conditions. In the construction of means of transport, two types of titanium with different structures are mainly used (alpha titanium and alpha + beta titanium). There will certainly soon be a need to weld these two dissimilar materials together. This is a research gap. An absolute novelty is the attempt to weld dissimilar titanium alloys without using a protective vacuum chamber. The purpose of this article is to establish the correct parameters for this process.
