In 2017, with the rise of domestic laser enterprises, domestic high-performance fiber lasers were promoted. Among them, domestic laser manufacturers, represented by Ruike Laser, have launched 500 W, 1000 W and 3300 W medium-high power lasers. Fiber lasers have rapidly occupied the market with the characteristics of good beam quality, small size, small energy consumption, good equipment stability and compatibility, so that laser processing also has a larger market share, and rapidly replaced the previous lamp-pumped solid-state lasers. At this time, some people found business opportunities, among which the laser equipment manufacturing enterprises represented by Chuangheng Laser took the lead in launching the handheld fiber laser welding machine with 500 W fiber laser as the light source, which can be said to be "the second generation of handheld laser welding machine". What progress has the second generation made compared with the first generation? The second generation hand-held laser welding machine has the following advantages because it uses fiber laser as the light source: (Also take 500 W as an example)   The first generation of laser handheld welding The second generation laser handheld welding Equipment volume At least more than 3 cubic meters About 1 cubic meter Equipment energy consumption The maximum is about 15 ° per hour The maximum is about 2 ° per hour Weld penetration About 0.6mm About 1mm welding speed 5mm/s 25mm/s Light emitting mode Pulse type Pulse and continuously adjustable Weld spot diameter 0.6 mm minimum 0.1mm minimum Heat affected zone Small, not easy to deform Small, not easy to deform It can be seen from the above table that the performance of the "second generation handheld laser welding machine" is much better than that of the first generation of products. It not only continues the advantages of the first generation, but also overcomes many shortcomings. It improves efficiency, reduces costs, and improves processing performance. It can weld some products with strength requirements, which are more suitable for welding materials less than 1.5 mm, and the equipment price is similar, so it has a large number of customers.
