Laser welding machine is often called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc., is the material processing laser welding machine.
Two, the working principle of the laser welding machine
Laser welding is the use of high-energy laser pulses on the material for a small area of localized heating, the energy of laser radiation through heat conduction to the internal diffusion of the material, the material will be melted to form a specific melt pool. Laser welding machine is a new type of welding method, mainly for thin-walled materials, precision parts welding, can realize spot welding, butt welding, stack welding, sealing welding and so on.
Three, types of laser welding machine
1, according to its mode of operation can often be divided into laser mold burner (manual laser welding equipment), automatic laser welding machine, jewelry laser welding machine, laser spot welding machine, fiber optic transmission laser welding machine, vibration mirror welding machine, handheld welding machine, etc., special laser welding equipment has a sensor welding machine, silicone steel sheet laser welding equipment, keyboard laser Welding equipment.
2, according to the weldable graphics: points, straight lines, circles, squares or any plane drawn by AUTOCAD software.
Four, the advantages of laser welding machine
1, fast speed, depth, deformation is small.
2, can be welded at room temperature or special conditions, welding equipment device is simple. For example, the laser through the electromagnetic field, the beam will not be deflected; laser in a vacuum, air and some kind of gas environment can be welded, and can be through the glass or transparent to the beam of the material to be welded.
3, can weld refractory materials such as titanium, quartz, etc., and can be welded to dissimilar materials with good results.
4, laser focusing, high power density, in high power device welding, depth to width ratio of up to 5:1, up to 10:1.
5, can be micro welding. The laser beam can be focused to obtain a very small spot, and can be accurately positioned, can be applied to high-volume automated production of micro, small workpieces in the group welding.
6, can be welded inaccessible parts, the implementation of non-contact long-distance welding, has great flexibility. Especially in recent years, in the YAG laser processing technology using fiber optic transmission technology, so that laser welding technology has been more widely promoted and applied.
7, the laser beam is easy to realize the beam according to time and space, can be divided into light, can carry out multi-beam simultaneous processing and multi-station processing, for more precise welding provides the conditions.
