Aerospace Laser Welding Application Solutions

Laser manufacturing technology has great prospects for industrialization in the fields of national defense and aerospace. It has high efficiency, low energy consumption, short process, good performance, digital and intelligent.

The characteristics of energy。 In view of the status quo, China will continue to take advantage of the advantages of laser manufacturing technology, and change the status quo of key components and technologies in China's aerospace industry mainly relying on imports, and finally form a new generation of laser manufacturing industry chain in China.

Morningstar Technology combines laser welding technology with aerospace manufacturing technology as a mature technology to become an important means of aerospace lightweight alloy joints, connecting structural parts and some engine components in modern aerospace manufacturing. Play a decisive role.

Program recommendation:

High power laser welding

Titanium alloys are widely used in aircraft, and have been converted from primary bearing structural members to main structural members。 Aluminum alloys are the main structural materials for launch vehicles and various spacecraft。 By comparing the traditional welding and laser hybrid welding of aluminum alloy and titanium alloy, the laser processing has the advantages of energy concentration, easy operation, high flexibility, energy saving, high quality and high efficiency。 

Aircraft alloy wall plate laser welding

Reasons for filler wire bonding: Aluminum and aluminum alloys have low strength at high temperatures, and liquid aluminum has good flow properties, and weld metal is prone to collapse during welding。

Advantages: low precision for seams and high weld strength.

Material selection principle: The purity of pure aluminum welding wire is generally not lower than the chemical composition of the parent metal, corresponding to or similar to the base metal, and the content of corrosion resistant elements (magnesium, manganese, silicon, etc.) is generally not lower than that of the parent metal. When welding dissimilar aluminum materials, the welding wire should be selected according to the base material with high corrosion resistance and high strength.
