As an important metal processing technology, welding plays an important role in industrial production and national defense construction. With the change of industrial structure and the development of science and technology, advanced welding structure is an effective way to reduce material consumption and reduce structure quality. Various welding technologies have broad application prospects. With the development of the titanium industry, its welding technology has attracted more and more attention.
Titanium has the advantages of high specific strength, corrosion resistance of seawater and other media, low temperature resistance, and high fatigue strength at high temperature, low expansion coefficient, good workability, etc. The structure built with it can be used in any natural environment. Can fully play its role. In ship applications, in addition to its characteristics of seawater corrosion resistance and high specific strength, it also has the advantages of non-magnetic, sound transmission, shock resistance and other advantages. The use of titanium and titanium alloys in ships greatly extends the service life of the equipment , Reducing the weight, improving the technical and tactical performance of equipment and the entire ship, so titanium is an excellent ship structure material.

This welding technology has broad application prospects. With the development of the titanium industry, its welding technology has attracted more and more attention. Titanium has a higher melting point and poor thermal conductivity. Therefore, it is easy to form a larger molten pool due to improper parameter selection during welding, and the temperature of the molten pool is high. This makes the weld and heat-affected zone metal stay at high temperature for a longer time, and the grain growth tendency is obvious, which reduces the plasticity and toughness of the joint and causes cracks. Therefore, the welding process of titanium and titanium alloys is a problem that needs to be solved continuously.
