How to Weld Titanium Alloy with Laser Welding Technology?

Mar 11, 2020

Titanium alloy has many unique excellent properties, such as high compressive strength and excellent corrosion resistance, and has been well applied in aviation, medical and other industries. It is also because of this property that titanium alloy materials are not well welded. Traditional welding methods are not suitable for titanium alloys. Laser welding technology can solve this problem.

Titanium alloy has good welding performance. Generally, the mechanical properties of the joint after welding are lower than the base material, but it can still meet some application requirements. Because titanium is a lively metal element, such as the use of argon arc welding, plasma welding, etc., after welding, the joints are prone to embrittlement due to impurities such as gas, resulting in pores and cracks.

Laser welding has the advantages of low thermal impact, small deformation of materials, and environmental protection. Laser welding of titanium alloys, whether it is titanium alloy parts or titanium alloy products, can be fixed by fixtures, using high-purity argon as a protective gas, Welding can be performed according to the color after welding. Laser welding of high-temperature titanium alloys can also obtain joints with good strength and plasticity

With the development of technology, titanium alloy materials will gradually become one of the materials with great development potential due to their own advantages and the gradual reduction of prices. In the future, they will surely get wider applications and more markets. And laser welding will play a certain role in this process, and the field of laser welding is also constantly expanding.
