Laser welding machines have brought a lot of convenience to production manufacturing. With the increase in user demand, there are also more and more types of laser welding machines on the market. However, which laser welding machine is suitable for oneself needs to be considered from multiple perspectives.
The introduction and principle of laser welding machine
Laser welding machine, also commonly known as laser welder or laser welding equipment, is a machine used for material processing during laser welding. According to its working mode, it can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, laser spot welding machine, and fiber optic transmission laser welding machine. Laser welding uses high-energy laser pulses to locally heat materials in small areas. The energy of laser radiation is diffused into the material’s interior through heat conduction, melting the material and forming a specific molten pool. It is a new type of welding method，which mainly used for welding thin-walled materials and precision parts, and can achieve spot welding, butt welding, overlay welding, seal welding, etc. It has a high depth-to-width ratio, narrow welding width, small heat-affected zone and deformation, fast welding speed, smooth and beautiful welds, no treatment is required or only simple post-weld treatment is required after welding, high welding quality without porosity, precise control, small focused spot, high positioning accuracy, and is easy to realize automation
The features of laser welding machine
Laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision materials, and can realize a variety of welding methods. It has fast welding speed, small weld width, small heat-affected zone, smooth and beautiful weld seam, and high quality. precise positioning and control, It can not only weld the same material but also weld different materials and is widely used in various industries
1、Consider the power of the laser welding machine
the higher the power of the laser welding machine, the higher-end the laser and cooling system ,and the overall price will be higher,Of course, the deeper the welding depth. It is best to choose the corresponding power based on your own welding needs, which can handle daily welding work. Otherwise, if the power is too small, the welding will not be strong enough, and if the power is too large, it will not be utilized.
2、Consider the type of laser
Common lasers includes CO2 lasers, Nd:YAG lasers, and fiber lasers. CO2 lasers can meet the needs of both welding thick and thin materials at the same time; Nd: YAG lasers have large spots, narrow pulses, and large processing ranges; fiber lasers can penetrate thick plates at high speed, with stable performance and accurate welding.
3、Consider the use of laser welding machine
Laser welding machines are divided into manual, semi-automatic and automatic. Manual laser welding machines require operators to control the welding process, which is suitable for small-scale enterprise processing and manufacturing; semi-automatic laser welding machines are slightly larger in size, suitable for medium and large enterprises manufacturing;; fully automatic laser welding machines are dominated by computers during welding, and the welding efficiency is high. Suitable for large-scale enterprise production and use.
4、Consider the brand and price of laser welding machine
There are many brands of laser welding machines, such as TRUMPF in Germany, IPG in the United States, and Chinese laser welding machine manufacturers. Good equipment generally uses high-quality components. Chinese laser welding machines are more affordable in terms of price, and you need to choose reasonably according to your budget.
5、Consider the manufacturer’s strength and after-sales service.
The comprehensive strength of the manufacturer is the premise of production and research and development, and it is also the guarantee of the quality of the laser welding machine. After-sales problems after purchase can be solved in time to provide maximum protection.
