The handheld fiber laser welding machine is a new generation of laser welding equipment. It belongs to non-contact welding. The operation process does not require pressure. Its working principle is to directly irradiate a high-energy intensity laser beam on the surface of the material. Through the interaction between the laser and the material, the material is melted inside, and then cooled and crystallized to form a weld.
The handheld fiber laser welding machine fills the gap of handheld welding in the laser equipment industry, subverts the working mode of the traditional laser welding machine, and replaces the previous fixed optical path with a handheld one. It is flexible and convenient, with a long welding distance, and also makes it possible to operate laser welding outdoors.
Handheld welding is mainly aimed at laser welding of long-distance and large workpieces, overcoming the limitations of the workbench travel space. The heat-affected area is small during welding, which will not cause deformation, blackening, or traces on the back of the workpiece. In addition, the welding depth is large, the welding is firm, and the melting is sufficient. It can not only realize thermal conduction welding, but also continuous deep melting welding, spot welding, butt welding, lap welding, sealing welding, seam welding, etc.
This process subverts the working mode of traditional laser welding machines. It has the advantages of simple operation, beautiful welds, fast welding speed and no consumables. It can perfectly replace traditional argon arc welding, stainless steel plates, iron plates, aluminum plates and other metal materials for welding.
Advantages of handheld laser welding machine
1. Wide welding range: The handheld welding head is equipped with 5m-10M original optical fiber, which overcomes the limitations of the workbench space and can be welded outdoors and at long distances;
2. Convenient and flexible to use: The handheld laser welding is equipped with a mobile pulley, which is comfortable to hold and can adjust the workstation at any time without fixed workstations. It is free and flexible and suitable for various working environment scenes.
3. Multiple welding methods: It can realize welding at any angle: lap welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, etc. It can weld various workpieces with complex welds and irregular shapes of larger workpieces. It can realize welding at any angle. In addition, it can also complete cutting and welding and can switch freely between cutting and welding. It only needs to replace the welding copper nozzle with the cutting copper nozzle, which is very convenient.
4. Good welding effect: Handheld laser welding is hot melt welding. Compared with traditional welding, laser welding has higher energy density and can achieve better welding effect. The welding area is less affected by heat, not easy to deform, blacken, or have traces on the back. The welding depth is large, the melting is sufficient, and it is firm and reliable. The weld strength reaches or even exceeds the parent material itself, which cannot be guaranteed by ordinary welding machines.
5. No need to polish the weld: After traditional welding, the welding point needs to be polished to ensure smoothness and no roughness. Handheld laser welding, on the other hand, has more advantages in processing effect: continuous welding, smooth without fish scale pattern, beautiful without scars, and less subsequent polishing process.
6. No consumables for welding: In most people's impression, welding operation is "goggles in the left hand and welding wire in the right hand". But with a handheld laser welding machine, welding can be easily completed, and the material cost in production and processing is reduced.
7. With multiple safety alarms, the welding nozzle will only be effective when the switch is touched by the metal. The light will be automatically locked after the workpiece is removed, and the switch has body temperature sensing. High safety, ensuring the safety of operators during work.
8. Save labor costs: Compared with arc welding, the processing cost can be reduced by about 30%. The operation is simple and easy to learn, and the technical threshold of the operator is not high. Ordinary workers can start work after a short training, and can easily achieve high-quality welding effects.
Comparison between handheld laser welding machine and argon arc welding
1. Energy consumption comparison: Compared with traditional arc welding, handheld laser welding machines save about 80% to 90% of electricity, and processing costs can be reduced by about 30%.
2. Welding effect comparison: Laser handheld welding can complete the welding of dissimilar steels and dissimilar metals. Fast speed, small deformation, small heat-affected zone. Beautiful, smooth welds, no/few pores, no pollution. Handheld laser welding machines can perform small open parts and precision welding.
3. Subsequent process comparison: Laser handheld welding has low heat input, small workpiece deformation, and can obtain beautiful welding surfaces without or only simple processing (depending on the requirements of the welding surface effect). Handheld laser welding machines can greatly reduce the huge labor costs consumed in polishing and leveling processes.
Application fields of handheld laser welding machine
It is mainly used for fixed positions of large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames, stainless steel wash basins and other large workpieces, such as internal right angles, external right angles, and flat welds. The heat affected area is small during welding, the deformation is small, and the welding depth is large, and the welding is firm. It is widely used in the kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel products industry, stainless steel engineering industry, door and window industry, handicraft industry, household goods industry, furniture industry, auto parts industry, etc.
