Laser welding machine can weld a variety of metals, its ideal welding effect has been a lot of people's attention, and its appearance makes everyone in the purchase of another option, but the power of laser welding there are big and small, is not the greater the power can be welded the thicker the plate?
Laser welding machine principle
Laser welding works by utilizing a high degree of directional consistency of the laser beam. The laser is generated by the laser, and the material is heated to increase the energy, which is rapidly transmitted to the inside of the material through heat conduction, causing the material to liquefy and form a molten pool to achieve the purpose of welding.
Advantages of laser welding machine
1. It is used for welding thin-walled materials and fine parts, and can realize omni-directional welding.
2. Fast welding speed, small weld width, white and smooth weld joints.
3. small heat-affected zone, small deformation, no need or only a small amount of processing treatment.
4. able to weld materials which are difficult to be welded by other equipments, such as titanium, etc.
5. can carry out micro welding, small workpiece resistance welding, realize automatic mass production.
6. high positioning accuracy, can weld various shapes of workpieces and parts that are difficult to access manually.
Laser welding machine can weld how thick
Generally speaking, the current laser welding machine can weld about 8mm thickness of the material, respectively, with the welding power, welding material and welding speed related.
First, the welding thickness determines how much power should be used, that is to say, the greater the thickness of the workpiece to be welded, the choice of laser welding machine should tend to be more powerful.
1. 1500W laser welding machine: welding less than 4mm thickness of the plate effect is good.
2. 2000W laser welding machine: welding less than 6mm thickness of the plate with good results.
3. 3000W laser welding machine: welding less than 8mm thickness of the plate with good results.
Second, different welding materials for laser absorption is not the same, welding needs to be flexible according to the welding material to adjust the power size to meet the welding thickness.
Third, the welding speed will also affect how much heat input welding, welding speed is too slow, the heat input is too large, easy to burn through the workpiece, welding speed is too fast, the heat input is too small, easy to weld through the workpiece.
Laser welding machine is a new type of efficient welding equipment, the greater the depth of fusion, the greater the thickness of the weld; the smaller the spot, the more concentrated energy, the stronger the weld. For example, welding 2mm thick stainless steel plate, you can choose 1500W laser welding machine, welding speed will be faster.
