How to select the appropriate power for a laser welding machine?
There are various types of laser welding machines. Besides the machine laser welding machines and refrigerant laser welding machines that have been highly discussed recently, the most common one is the handheld laser welding machine.
Regarding the advantages of Laser welding handheld machine:
1. Wide welding range: The handheld welding head is equipped with a 5m-10m original optical fiber, which overcomes the limitation of workbench space and enables outdoor welding and long-distance welding.
2. Convenient and flexible to use: The handheld laser welding machine is equipped with moving pulleys, has a comfortable grip, and allows for adjustment of the work station at any time. It does not require a fixed work station, is free and flexible, and is suitable for various working environments and scenarios.
3. Multiple welding methods: It can achieve welding at any angle, such as lap welding, butt welding, vertical welding, fillet welding, internal corner welding, external corner welding, etc. It can weld workpieces with various complex welds and large workpieces with irregular shapes, realizing welding at any angle. Moreover, it can also perform cutting. By simply replacing the welding copper nozzle with a cutting copper nozzle, free switching between welding and cutting can be achieved.
After understanding the handheld welding machine,
how to choose the power exactly?
The power selection of a laser welding machine is not about the higher the power, the better. The power depends on complex factors such as material characteristics, welding quality requirements, and equipment compatibility. Because low-power lasers are good at fine operations, such as welding thin plates and precision electronic components, they can effectively reduce the heat-affected zone and ensure that the physical properties of the materials around the welding area are not damaged.
Therefore, Laser welding handheld machine have become the first choice in many industries such as stainless steel products, kitchen and bathroom, home appliances, and advertising.
For Laser welding handheld machine, the welding power varies with different thicknesses and materials. How to choose according to the material?
