The main advantage of laser welding machine is that
What are the characteristics of laser welding and spot welding, and how about their respective strength? Is laser welding more advanced than spot welding? Or laser welding is better than spot welding. Question time: 2012-11-27 14:22, experts reply: Hello! About you, the characteristic of laser welding is the first by the welding deformation of the workpiece is extremely small, almost no gap connection, weld depth / width ratio, in high power devices when welding, the depth to width ratio is 5:1, the maximum of 10:1, followed by the weld of high strength, high welding speed, weld is narrow, and usually a good surface state that eliminates welding cleaning work, appearance than traditional welding should be beautiful. In addition, laser welding can weld inaccessible parts, the implementation of non-contact remote welding, with great flexibility, but can only be used for sheet laser welding, laser welding process of the welding penetration depth is not enough, not the chassis and frame. This can be done by spot welding, but the welded joint of the spot welds the two sheets together to form a 15mm laminate, which affects both beauty and weight of the car. Laser welding must be the most advanced body welding technology at present, but it is impossible to adopt laser welding.
1., high speed, large depth, small deformation.2. can be welded at room temperature or under special conditions. The welding equipment is simple. For example, the laser passes through the electromagnetic field, and the beam does not deflect; the laser can be applied in vacuum, air, and some gas environment and can be welded by glass or transparent material of the beam.3., welding refractory materials, such as titanium, quartz and so on, and can be applied to the opposite sex welding, the effect is good.4. after laser focusing, the power density is high, and when the high power device is welded, the aspect ratio is up to 5:1, and the maximum is 10:1.5. micro welding can be carried out. After the laser beam is focused, a small spot can be obtained, and the laser beam can be accurately positioned. The utility model can be applied to the welding of micro and small workpieces in a large number of automatic production.6., welding difficult to reach parts, the implementation of non-contact long distance welding, with great flexibility. Especially in recent years, in the YAG laser processing technology, the use of fiber transmission technology, laser welding technology has been more widely promoted and applied.7. laser beam is easy to realize the light beam is separated by time and space, and it can be processed simultaneously by multi beam and multi station processing, which provides the condition for more precise welding
