The principle of laser has been studied in the beginning of the 20th century, and the development of the first laser took place half a century later. on July 8, 1960, the American scientist Meyman invented the ruby laser, since then people can get the nature and electromagnetic waves and stable frequency of the light source. During this period, the high intensity and concentration of lasers aroused interest in their industrial applications, especially in the field of welding.period laser marker Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. http://laserscheme.com/
Early research on laser welding focused on welding experiments on metallic materials. Through continuous experiments, researchers gradually realized that laser welding has the advantages of high welding speed, small heat-affected zone and high welding quality. Time came to the 70¨s, carbon dioxide laser and helium-cadmium laser¨s successful research and development, for welding technology provides new tools.
As laser technology becomes more and more mature, laser welding is gradually gaining applications in automotive manufacturing, aerospace and other fields. Laser welding equipment is beginning to enter the factory production line, especially in the welding of thin-walled materials outstanding performance.
Compared with the West, the development of laser welding technology in China started much later. It was not until 1980 that laser technology was introduced in China, and in 1985, the first domestic laser welding equipment was delivered in Shanghai, which marked the beginning of laser welding technology in China. In the following two to three decades, with the deepening of reform and opening up, China¨s laser technology began to develop rapidly, and today, China¨s overall laser technology level, especially laser welding, has not lost the West.
Nowadays, laser welding technology is developing rapidly, mainly reflected in the wide application of high-power lasers, the enhancement of the level of intelligence and automation, the enhancement of multi-material welding capability, as well as the advantages in micro-welding and environmental protection. The technology is also increasingly used in new energy, aerospace and other high-tech fields to meet the demand for high-efficiency, high-quality welding. As a green manufacturing process, laser welding is also in line with the concept of sustainable development.
The future of laser welding is promising. With the continuous advancement of high-power laser technology, welding efficiency and quality will be further improved to handle more complex material combinations and more demanding welding tasks. The application of laser welding in emerging fields such as renewable energy, electric vehicles and aerospace will continue to expand, promoting green manufacturing and sustainable development. Overall, laser welding technology will develop in a more efficient, smarter and environmentally friendly direction, providing strong support for technological innovation and manufacturing transformation in various industries.
