The word LASER originated as an acronym for Light Amplification By Stimulated Emission Of Radiation. Its characteristics, such as coherence, monochromatic, directionality and high output power, etc., are incomparable by other light sources.
The theory of laser welding is using pulse laser, which has high power density resulting in small heat-affected zones, working on the workpiece surface to realize. The pumping resource is Xenon lamp, which is lighted by laser power supply. After the flash lamp is discharged and charged by laser power supply, light will be achieved with frequency and pulse width. The Nd: YAG crystal absorbs the light, emission can spontaneous or stimulated, Hence, the light is amplified through an optical amplifier inside a resonant optical cavity, the pulse laser (wavelength is 1064nm) will obtained. The laser is amplifier and reflected (or delivered by optic fiber), focus on the workpiece surface of welding, with moving of working table, which is controlled by PLC or Industry PC, to realize laser welding.
Laser welding is a new versatile welding process, capable of welding thin material, fine components, used to spot welding, butt welding, lap welding and sealed welding. The laser beam provides a concentrated heat source, allowing for narrow, deep welds, high welding rates, low transfiguration, small heat affected zone and high welding speed. With high quality welding results, it no needs re-process after laser welding. The intensity and toughness of welds is as same as or higher the row material. Precise position, small laser spot, precise control, the process is easily automated with robotic machinery, can weld some irregularly forms.
Laser welding is suitable for welding stainless steel, aluminum, copper, gold, silver, titanium, nickel, stannum, Zinc, chromium, columbium etc and its alloy. Laser can weld between same material and different material, such as: Cu-Ni, Ni-Ti, Ti-Mo, Brass-Cu, low carbon steel-Cu.
It is widely used in varied fields, such as: Battery of mobile phone, Optical communication, Aerospace, Military, Scientific Research, Electronic components, Home appliance, Automatic parts, Hardware tool, Mould repairing, Jewelry, Medical equipment, Laser artwork, Solar cell
