Professional Fiber Optical Laser Welder Energy Feedback Type
Description
Our company is one of the few domestic professional laser welding company covering the whole field of welding applications, and thelaser output poweris from 5watts to 5000 watts. The key technologyof our company is theenergy negative feedback control for arbitrary waveform, details as follows:
1) Energy negative feedback control
The energy negative feedback control is to compare the output laser energy waveform with the actual output energy waveform in real time to determine the energy input of the pump lamp and then control the output energy. With the energy negative feedback control technology, the laser output energy can be accurately controlled within 2% range. At the same time, the following problems can be solvedwhich can lead to large fluctuations of laser output energy:
1-1) Thefluctuation of city electricity.
1-2) The difference of each discharge of xenon lamp.
1-3) The reduction of output laser energy caused by xenon lamp aging.
2) Arbitrary waveform setting
In the processing of production, for copper, aluminum, gold and other materialsas itshave a high surface reflectivityfor the 1064nm wavelength laser, resulting in the processing have strength is not enough, welding surface is notbeautiful and other issues; for high-carbon and other materials, hot cracks, cold cracksand other issues occur in the process due to rapid quenching and rapid heating. For the above problems, by changing the energy fluctuation of the laser pulse to control the change of the laser energy during the welding process, the above problem is solved by using the method to achieve the best welding effect.
Advantages
► Optional CCD camera monitoring system, easy to observe and precise positioning.
► Uniform energy distribution of welding spot, the best spot needed for welding characteristics.
► Adapt to a variety of complex welds, spot welding of various devices, and within 1mm sheet of seam welding.
► Customized automatic fixture for mass production.
Features:
► Imported gold cavity, corrosion resistance, high temperature resistance, life 8-10 years, xenon lamp life’s more than 800 million times.
► Non-contact processing, stress free, noiseless, no pollution to the environment, which belongs to the green processing.
► High laser energy density, small thermal effect area, not easy deformation, less or no subsequent processing.
► Easy spot welding, stack welding, splicing and continuous welding.
► Good quality laser beam, high conversion efficiency and therefore high welding speed, high aspect ratio, high strength.
► Good welding quality, smooth and beautiful appearance.
► Solder joints non-pollution, weld strength and toughness at least equivalent to or stronger than the base metal.
► With energy negative feedback control function, the laser energy instability caused by the fluctuation of the grid, the aging of the xenon lamp and the change of the water temperature is eliminated, and realized the stable and high-quality welding processing. It is especially suitable for welding high reflectivity materials such as copper and aluminum.
Application
Laser welding can be used in welding stainless steel, aluminum, copper, gold, silver, chromium, nickel, titanium and other metals or alloys, can also be used for a variety of welding between different materials, such as: copper - brass, titanium - gold, Titanium - molybdenum, nickel - copper and so on.
Laser welding is widely used in the IT industry, medical equipment, communications equipment, aerospace, machinery manufacturing, battery manufacturing, elevator manufacturing, craft gifts, household appliances manufacturing, tooling, gears, automobile shipbuilding, watches and clocks, jewelry and other industries.
