The Transformative Power of Laser Technology in the Mechanical Industry
In the 1970s, the United States made two groundbreaking research contributions in the field of laser welding, leading to the development of laser treatment technology in the mechanical manufacturing industry. By the end of the 1980s, the use of laser technology had increased exponentially, with the fastest growth seen in laser welding, laser cutting, and laser drilling. These advancements have enabled the mechanical industry to reap numerous benefits, including contactless treatment, precision, good controllability, simple procedures, economical materials, and reduced pollution.
At the dawn of the 21st century, China’s Wuhan Falilai Cutting System Engineering Co., Ltd., in collaboration with the National Key Laboratory of Laser Technology and the National Research Center for Laser Processing, launched a research group to develop a laser industry. This marked the beginning of high-power laser treatment technology in China’s mechanical industry, which has since become a game-changer.
The Power of Laser Technology
Laser treatment technology has revolutionized the mechanical industry due to its numerous advantages over traditional treatment methods. Some of the key benefits include:
- Contactless treatment, minimizing mechanical stress
- Precise treatment, allowing for good control and control
- Simple procedures, resulting in reduced processing time and costs
- Economical materials, reducing waste and environmental impact
- Reduced pollution, minimizing the ecological footprint
In this blog post, we will delve into the different types of laser treatment technologies used in the mechanical industry, exploring their applications, advantages, and limitations.
Laser Cutting: A Precise and Versatile Technology
Laser cutting is a high-speed and precise process that uses a high-power laser beam to vaporize the material being cut, creating a precise and clean cut. This technology is particularly useful for cutting through hard, fragile, and soft materials.
One notable example of a laser cutting machine is the CNC WIDE-FORMAT WALC4020, developed jointly by the National Laser Technology Laboratory and Wuhan Falilai (see Figure 1). This machine features a penetration detection, automatic concentration, punch, and cutting double flow control system, as well as a vertical lifting exchange table structure. These innovations have enabled the technical performance of the WalC4020 to exceed similar products and reach the international advanced level.

Laser Welding: A High-Speed and Low-Discard Technology
Laser welding is a high-speed production and treatment method that offers a contactless and non-deforming process, making it ideal for large-scale and continuous processing. This technology has been successfully applied in the production of car exhaust pipes, transmission parts, and other components, significantly increasing efficiency and reducing costs.
Another innovative application of laser technology is laser hardening, which uses a high-energy laser beam to quickly scan the surface of the cylinder bore, causing a small area with a thin surface layer (spot size) to rapidly heat up and increase in temperature. This process converts the surface layer into a hardened zone, exhibiting enhanced toughness and wear resistance. Compared to conventional hardening processes, laser surface hardening offers a shorter development history but has shown promising results, making it a new and innovative surface hardening treatment process.
Conclusion
Laser technology has revolutionized the mechanical industry, providing a contactless, precise, and efficient means of treatment. With the development of laser cutting, welding, and other technologies, the mechanical industry is poised to reap numerous benefits, including reduced processing time, costs, and environmental impact. As the industry continues to evolve, we can expect to see even more innovative applications of laser technology, driving further transformation and growth.
