With the increasing maturity of digital technology, the representative office of digital welding technology, digital control technology has been steadily entering the market. The Three Gorges Project, the West-East Gas Pipeline Project, the Aerospace Engineering, the Marine Engineering and other large-scale national basic projects, effectively promoted the advanced welding technology, especially the development and progress of welding. Automotive and parts manufacturing requirements of the automation of welding with each passing day. China's welding industry gradually to "efficient, automated, intelligent." China's welding automation rate of less than 30%, with the developed industrial countries, 80% gap. From the 20th century is not the country gradually in various industries to promote the basis of automatic welding welding - gas shielded welding, to replace the traditional manual arc welding, has achieved initial success. Can be expected in the future, the domestic automation welding technology will be an unprecedented pace.
Laser welding technology is widely used in the manufacture of foreign cars. According to statistics, in 2000, more than 100 pieces of tailored blank slab laser welding production lines were produced worldwide, and the annual production of 70 million pieces of blanks for car components, and continue to grow at a high speed. . Domestic production of imported models also use some cut blank board structure. Japan to CO2 laser welding instead of flash butt welding for steel rolling coil connection, thin plate welding research, such as the thickness of 100 microns below the foil, can not be welded, but through a special output power waveform YAG Laser welding to be successful, showing the broad prospects of laser welding. Japan is also the world's first successful development of YAG laser welding used in nuclear reactors in the steam generator thin tube maintenance, in the country also gear laser welding technology.
With the continuous development of science and technology, the application of laser welding machine more and more widely, and gradually penetrate into various fields in the industry, and laser welding machine, also known as laser welding machine, laser welding machine, laser processing machinery , According to its work is divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, light welding is the use of high-energy laser pulse on the material in a small area of ​​local heating, laser radiation Of the energy through the heat transfer to the internal diffusion of the material, the material is melted to form a specific molten pool in order to achieve the purpose of welding.
Finally, now the country is developing process, laser welding machine is the manufacturing, powder metallurgy, automobile industry and other sectors of the top priority, with the gradual recovery of the global economy and China's sustained and rapid economic development, the demand for laser welding machine Volume will gradually increase. Laser welding machine production and marketing enterprises should seize this golden opportunity to further consolidate the existing market, and strive to open up a broader potential market.
