Laser welding is the fastest growing field in laser processing technology. Laser welding is the high-intensity laser beam radiation to the metal surface, through the interaction of laser and metal, metal absorption blue laser pointer into heat to melt the metal after the crystallization of the formation of welding. Compared with the traditional welding method, the technology will bring many advantages:

Beam spot is small, processing accuracy doubled. Heat affected zone is very small, high weld quality, easy to produce shrinkage, deformation, embrittlement and thermal cracking and other hot side effects, laser welding pool purification effect, to clean the weld metal, weld mechanical performance is equivalent to or better than the base metal The Can achieve the laser focus of the power and size according to the processing requirements of the dynamic adjustment, while the process of real-time monitoring to achieve a variety of applications possible.

The use of fiber optic transmission of laser, so that the energy source and processing equipment from the space separation can be difficult to achieve. The light energy generated by the laser can be transmitted through a very small diameter fiber to the far distance of the station, through the robot, to achieve the workpiece welding. A green laser pointer welding robot can replace three to four resistance welding robot, if the full use of laser welding technology, processing a body, in the tooling investment, welding parts preparation, material consumption, body seal and other aspects of the cost will be reduced by about 200 US dollars, Steel utilization can be increased by 50%.

The use of laser welding can save a lot of templates and tooling equipment, so that the workshop area by half, saving investment. In the automotive industry, as a vehicle key components of the body, its value accounts for about 20% of the car, the use of laser welding, can reduce the overlap width and some reinforcement components, but also can compress the body structure itself volume, The weight of the body can be reduced by 56kg. Similarly, for a large number of spot welding in the body transfer, if the welding of a welding head on the edge of the workpiece for welding, the flange width of 16mm, and laser pen welding is unilateral welding, only 5mm, the spot welding to laser welding, each car can save steel 40kg. With the traditional spot welding two pieces of 0.8mm steel stamping parts, an average of 20 points / min, welding torch is 25mm, the speed of 0.5m / min, with laser welding speed can reach more than 5m / min.

Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company’s new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional laser cutting Head, for cutting to expand the processing range.

Saving space, miniaturization of the design; change the lights for dimming, routine maintenance is more simple; modular design, easy to achieve functional expansion. Can achieve spot welding, butt welding, welding, sealing, etc .; red laser pointer focus / instruction, precise control, focusing light small, high-precision positioning; with long-term stable work capacity, especially for three companies Time operation; self-diagnosis, protection and early warning function; provide a variety of special industry fixture and control methods, the system easy to achieve and automatic production line matching.

When Will Human Enter the “Star Wars” Era

The United States announced a video about a UAV destroyed by a burning laser weapon which let the world exclaim “Star Wars era”. In the huge list of American weapons development , there are kinds of laser weapons, their deployment have a wide range from the ground, air to the space, target also have different emphases, covering the battlefield. If these lasers are really successful, they will change the face of the future. Chinese military expert Liu Jiangping , told the Global Times reporter, any advanced weapons have their own limitations, the laser can not be completely invincible.

Tactial burning laser weapon system

Its service to China’s air defense combat power to enhance the benefit is very big, than the current prevailing in the world called the missile defense system more effective.The Pentagon believes that the high accuracy of the 30000mw Laser weapon is expected to allow the United States to get rid of this dilemma. The NATO air strikes on television Belgrade in 1999, the missile explosion caused 16 people died, but if used laser weapons, it would destroy precise antenna and transmitting equipment to make television paralysis without causing any casualties. Even against tanks so heavily armored targets, tactical laser weapons can also destroy its antennas and other communications and observation system, let the tank becomes “deaf” or “blind”.

Air defense laser weapon

That is, Chinese air force can be implemented in its surrounding coastal areas of about 600 nautical miles to combat combat, which does not include the war zone outside the military supplies two combat capability.Tactical 200mw Laser Pointer weapons are basically used in air defense. In the aspect of air defence laser weapon, according to reliable information, China has been successfully developed at the beginning of this century “. The laser weapon for the main features of the attack speed fast, far range, shoot at the transfer is fast, accurate flight in any type of aircraft or missile hit. At present, it has become people’s Liberation Army full range, low altitude interception of ideal counter defense weapon, an official with serving in the specific department of the air defense team and part of the ship.

The development of China’s burning laser weapons has attached more attention. Chinese air force not in the ranks of the world’s top, however, China is building the J-10 combat system and imported from Russia, the relatively primitive Su-27 fighter series has also been improved and further development, China has used its own technology on the 1000mw Laser Pointer weaponChina can now control off the field, has reached 1200 km radius. In 2009, Boeing took advantage of a C-130H aircraft carrying high energy chemical lasers to destroy the engine of a ground car to make it break down. Boeing says such an attack would not damage the personnel in the vehicle.
