Laser welding machine of choose and buy pay attention to?

Laser welding machine of choose and buy pay attention to? Laser welding in all areas of application are more popular. Especially the manufacturing industry, the automotive industry, electronic industry, biological medicine, powder metallurgy and other fields, the traditional methods can not meet demand, instead, the laser welding technology. Market demand for laser welding equipment is higher and higher, performance parameters affecting the quality of laser welding machine also has a lot of. Then, manufacturer in laser welding equipment of choose and buy, should pay attention to what issues? 1. Laser pulse energy of laser pulse energy, refers to a single laser pulse can large output energy, unit is the J ( The joule) 。 Power certain cases, a single laser pulse energy is higher, the lower the emission frequency. Laser pulse of the laser energy is a main parameter, it determines the laser can produce the large energy. 2. Laser speckle focused laser spot diameter on diameter is reflected laser design performance of a very important parameter, the unit is mm ( Mm) It decided to laser power density and processing range. If the laser optical design reasonable, advanced laser energy focus, focus accurately, can control the laser spot diameter in 0. 2mm - 1. The range of 5 mm, and can control the laser focus diameter at 0. 2 mm is a strict test of laser generator. Generally small manufacturer of laser equipment, because want to reduce the cost, the laser device processing crude, design is not rigorous, making it difficult to accurately focus, the laser spot diameter of the laser welding machine can not meet the standard of 0. 2 mm this is caused by laser irradiation area actual is too big, appear ablation phenomenon of welds, the influence of processing materials are particularly vulnerable to this kind of phenomenon, sometimes even make mold scrapped. Wuhan south China university of technology engineering co. , ltd. production of laser welding equipment, laser speckle minimum can reach 0. 2 mm, and can be in 0. 2 mm and 1. 5 mm in the range of stepless adjustment, reached the international advanced level. South China university of technology of the laser medium and small power laser welding equipment mainly includes: continuous fiber laser welding machine, optical fiber transmitting laser welding machine, laser spot welding machine, etc. 3. The frequency of the laser pulse frequency of laser pulse is reflected laser in the ability to hit how many pulse in the course of a second, unit is Hz ( Hz) 。 Metal welding, for example, the weld metal is to use the laser energy, and under the condition of the laser power constant, the higher the frequency, the smaller each laser output energy, therefore, we need to ensure enough molten metal of the laser energy, considering the speed of processing, to determine the output frequency of the laser. In south China university of technology production of optical fiber transmitting laser welding machine as an example, the frequency of the laser pulse is 1 - - - - - - 100 hz grading is adjustable, can fully meet the precision welding of different materials, different shape mold processing, the solder joint is smooth and beautiful, smooth weld pore-free, weld strength and toughness at least equivalent to or even more than the base metal. 4. Feedback control method, power waveform choice when choosing laser power waveform, in general, under the condition of the same input laser energy, pulse width, the width, the bigger the welding spot; The higher laser power waveform peak power, the deeper the welding spot.
