Laser welding is the most rapidly growing field of laser processing technologies. Laser welding is a high intensity of laser radiation to the surface of metal, with a laser interaction with metal, metal absorption laser is converted into heat energy to make metal melt cooling crystallization after welding. Compared with the traditional welding methods, technology can bring A lot of advantages: A small beam of light spots, the machining accuracy be doubled. Minimal heat affected zone, high weld quality, not easy to produce shrinkage, deformation, embrittlement and hot side effects such as hot crack, laser welding molten pool purification effect, can purify the weld metal, welding seam mechanical property is equal to or better than that of the parent metal. B can realize the power of the laser focus and size adjusted dynamically according to the requirements of processing, real-time monitoring of machining process at the same time, may achieve a variety of applications. C using optical fiber transmission of the laser, so that the energy source and processing equipment from spatially separated can be realized without difficulty. Produced by the laser light through a small diameter optical fiber transmission to the distant location, by robot, welding of artifacts. D a laser welding robot can replace 3 to 4 sets of resistance welding machine, if make full use of the laser welding technology, processing a body, the equipment investment, welding preparation, the cost of material consumption, body sealing, etc will reduce about $200, utilization rate of steel can be increased by 50%. Using laser welding can save a lot of samples and tooling equipment, halve the workshop area, save the investment. In the auto industry, as a key part of vehicle body, its value accounts for about 20% of the whole car, using laser welding, can reduce the width of the lap and some strengthen parts, still can compress the volume of a body structure itself, that alone can reduce 56 kg body weight. Body ZhuanPei of a large number of spot welding, also, for if you even have a welding head welding on the clip on the edge of the workpiece, the flange width need 16 mm, and laser welding is single side welding, only need 5 mm, changed the spot welding to laser welding can save steel 40 kg per car. With the traditional spot welding welding two pieces of 0. 8 mm steel plate stamping parts, the average is 20 points/min, the welding torch is 25 mm, the velocity is zero. 5 m/min, with laser welding speed can reach more than 5 m/min laser welding machine, host, power supply, workbench, refrigeration unit separation design; The machine into the new type of condenser cavity, its high photoelectric conversion efficiency and beam quality, reflecting surface and cooling medium without contact, cavity long service life, convenient replacement of xenon lamp without light way to adjust. PLC control and computer control two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, equipped with coaxial, paraxial gas protection device, improve the welding quality. And optional laser cutting head and cutting processing, to expand the processing scope. 1, save space, the miniaturization design; 2, changing lamp dimming, free maintenance more simple; 3, modular design, easy to extend functionality. Can realize welding, butt welding, welding stack, seal welding, etc. ; 4, red light focus/instructions, precise control, small focusing spot, achieve high precision positioning; 5, have the ability to work stably for a long time, especially suitable for enterprise system of three shifts operation for a long time; 6, self diagnosis and protection and warning function; 7, offers a variety of special fixture and control mode, the system is easy to implement and form a complete set of automatic production line; Metal laser welding equipment recommendation: preferential deals offer 4007001618 【 Metal laser welding equipment 】 Suitable for all kinds of complex welding, the welding of different equipment and 1 mm thick seam welding; Multi-channel fiber optic mode, welding transfer at the same time; 【 Mould laser welding equipment 】 Applicable mould industrialized, used for precision mold repair, such as digital products, mobile phones, toys, automobile, motorcycle, mold and other mold manufacturing and molding industry. 【 Gold and silver jewelry laser welding 】 Mainly used in jewelry, such as electronics, communications, handicrafts and other industries; 【 Large laser welding 】 Application in automobile body covering parts of compound, such as car door, side wai, window, floor, warehouse, the warehouse before, trunk lid.
