Analysis of the future development direction of laser cutting machine industry

After decades of development, China's laser cutting equipment has become an industrial scale high-tech industries, China now has a certain scale of cutting equipment enterprises about 300. In 2015, the laser industry chain value of about 80000000000 yuan, mainly including: laser processing equipment industry reached 35 billion yuan (high power laser device which is used for cutting and welding, marking the 67% share of the market); laser processing applications in industry, electronic industry, light industry, military and medical industries reached 45 billion yuan. Changchun is responsible for the equipment is expected in the next three years, the average growth rate of China's laser industry average industry will not be less than 20%.
China in 2015 sales of laser cutting machine about 3000 units, is still showing an increasing trend, the estimated annual demand in the next million units. Is the formation of a series of laser cutting products, from power to high-power, from two-dimensional to three-dimensional cutting, from small to large format cutting. Hope that the series of cutting machine industry, can drive optical machinery, high-power optical lens, laser processing CNC system and machine tool industry chain perfect.
With the increasing popularity of laser cutting equipment, cutting accuracy continues to improve, market has laid a foundation for the laser welding, laser welding of thin sheet metal future market than laser cutting is bigger, must now do the basic product technical work, start from the high-end automotive applications start, gradually spread to the sheet metal industry.
In the future, the main development direction of laser cutting equipment presents the following five aspects.
1, laser processing technology, laser welding robot. Based on the laser processing system of the robot, it can be used to process the parts which are difficult to be processed by the traditional method. It is applied in the automobile industry. The resistance spot welding is changed to the laser welding, the welding speed is increased by 10 times, the strength is increased by 20%. The stamping of different material and thickness of blank with laser welding together after stamping, can greatly reduce the number of mold, material utilization rate increased by more than 10%. Laser remote welding is becoming a kind of method to replace the resistance spot welding of the traditional automobile body. The technology of laser remote scanning welding plays an important role in the technical and economic advantages of single side and non contact laser welding.
Using high power fiber lasers or laser discs, 6 axis robot research and 3 axis linkage galvanometer control system, laser scanning welding process planning for automobile chassis remote production line and production line of automobile door remote scanning laser, laser scanning remote welding technology and quality detection technology, meet the efficient location of 3D body joints, door laser welding the length is more than 4000mm, laser welding plate length is larger than 4000mm, the laser welding speed is more than 30m/min.
