The aerospace industry’s rapid growth worldwide has led to increased demand for intelligent manufacturing and laser applications. Laser technology offers several advantages in aerospace manufacturing, including high speed, efficiency, safety, and stability. This article explores the application of laser welding, laser cleaning, and 3D printing technology in the aerospace industry, highlighting their significance in driving advancements in manufacturing capabilities.

Laser Welding in Aerospace Manufacturing:

Dual-beam laser welding technology has transformed the aerospace manufacturing industry, particularly in addressing welding challenges in T-joints between panel structures and stiffeners. By utilizing two laser beams simultaneously, this technique minimizes welding-induced deformation and ensures shape accuracy. It has found widespread adoption in both foreign and Chinese aviation manufacturing fields. Laser welding is applied to various aerospace components, including longitudinal bone welding, panel welding, and pure titanium welding of satellite components.

Laser Cleaning for Aerospace Components:

Laser cleaning technology provides efficient and precise cleaning solutions for aerospace applications. It is used to clean oxide films before welding rockets, structural cabins of launch vehicle tanks, and aeroengine blades. The United States has successfully implemented laser cleaning for surface cleaning of fighter jets and transport aircraft. Compared to traditional cleaning methods, laser cleaning eliminates the need for chemicals, reduces environmental pollution, avoids part damage or stress, and offers flexibility and efficiency. Aerospace applications for laser cleaning include aircraft engine parts scale/oil cleaning, rocket storage box oxide film cleaning, and rust removal of aircraft parts.


3D Printing Technology in Aerospace Manufacturing:

3D printing technology, also known as additive manufacturing, has gained significant attention in the aerospace industry due to its ability to produce complex parts with high precision using lightweight materials. It eliminates the need for traditional tools and fixtures, reduces processing procedures, and shortens the manufacturing cycle. NASA has been a pioneer in applying 3D printing in aerospace, producing full-scale copper-alloy rocket engine parts to reduce costs. Chinese research institutions and enterprises are also actively exploring and leading in 3D printing technology for aerospace applications, benefiting areas such as aeroengine manufacturing and propeller blade manufacturing.


Laser Technology Conclusion:

Laser technology has become indispensable in the aerospace manufacturing industry, offering solutions for welding, cleaning, and additive manufacturing. The advancements in laser welding techniques, laser cleaning processes, and 3D printing technology have revolutionized the industry by improving efficiency, precision, and cost-effectiveness. With ongoing developments in laser technology, the aerospace industry is poised to achieve further advancements in manufacturing capabilities, contributing to the growth of the global aerospace market.
