Continuous 2000W laser welding machine is a kind of laser welding machine. It can greatly improve the efficiency of mechanical production and greatly increase economic benefits. It is welcomed and loved by mechanical manufacturers. The selection of the welding process method of continuous fiber laser welding machine mainly depends on factors such as material type, structural design, and structural stress. For welding requirements that require higher laser welding machine speed, lower welding heat input, smaller heat-affected zone (HAZ) and welding distortion, the laser welding process can usually provide an ideal solution. A variety of welding such as composite welding of stainless steel, carbon steel, gold, silver, aluminum, tool steel, nickel alloy, titanium, brass and copper can be completed by one machine, such as thermal conduction welding, spot welding and deep penetration welding Craft.
The medium and low power continuous fiber laser for welding thin metal plates of continuous fiber laser welding machine can weld various thin plates at high speed. With the use of a galvanometer and a long focal length lens, a smaller spot size can be formed to realize remote welding, which will bring many advantages in actual operation. For example, the fiber laser remote welding workstation can complete the welding of the entire door panel; when performing a robot system During integration, the entire body can be welded by lap welding or wire welding. In addition, the battery pack and pressure sealing ring can be sealed and welded. Quasi-continuous fiber lasers can perform pulse welding with high peak power and low average power, and are suitable for applications with low heat input. Typical applications are high-speed spot welding such as blades, welding of devices under the hood of automobiles, etc.
The metal thick plate welding fiber laser of continuous fiber laser welding machine has been widely used in the welding of various metal thick plates. Compared with the traditional CO2 laser welding process, the fiber laser welding process has obvious advantages, which is mainly due to the lower reflection coefficient of the metal material to the 1070 nm fiber laser. The advantages of high-power fiber lasers are particularly obvious when welding metal materials with high reflection coefficients such as aluminum and copper. The high-brightness characteristics of the fiber laser can significantly reduce the sensitivity of the welding process to the focus position, thereby reducing the difficulty of achieving high-quality welding. Other application examples of fiber laser welding of thick metal materials include full penetration welding of transmission components and deep penetration welding of large thickness steel plates in industries such as ships and petroleum pipelines.
The definition of metal welding by laser welding machine:
Laser welding machine metal electric welding is a kind of laser welding equipment that couples a high-energy laser beam into an optical fiber, and after long-distance transmission, it is collimated into parallel light by a collimator, and then focused on the workpiece for welding. For parts that are difficult to access by welding, flexible transmission non-contact welding is implemented, which has greater flexibility. The laser beam of the fiber transmission laser welding machine can realize the splitting of time and energy, and can process multiple beams at the same time, which provides conditions for more precise welding.
What are the highlights of laser welding machine metal welding:
1 Beautiful welding seam, no welding scar, no discoloration, no need for follow-up polishing;
2 The welding is firm, and the weld strength reaches or exceeds the base metal itself;
3 Suitable for tailor welding, stitch welding, internal and external fillet welding, arc welding, irregular shape welding, etc.;
4 The complete set of equipment is highly functional, meets ergonomic design, and is suitable for various working environment scenarios;
5 Proprietary laser safety operation protection function to ensure the safety of operators during work;
6 The operation is simple, easy to learn and quick to get started, the technical threshold of operators is not high, and labor costs are saved.
Compared with argon arc welding
Energy consumption comparison:
Compared with traditional arc welding, the handheld laser welding machine saves about 80% to 90% of electric energy, and the processing cost can be reduced by about 30%.
Welding effect comparison:
Laser hand-held welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation, small heat affected zone. The weld seam is beautiful, smooth, no/less porosity, and no pollution. The handheld laser welding machine can be used for small open parts and precision welding.
Follow-up process comparison:
When laser hand-held welding, the heat input is low, the deformation of the workpiece is small, and the beautiful welding surface can be obtained, without or only simple treatment (depending on the requirements of the welding surface effect). The handheld laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.
The higher the accuracy of the metal word laser welding machine, the better; but the higher the accuracy, the higher the cost of the laser welding machine's workbench, so if necessary, choose a workbench that suits you. Then the shielding gas used in the laser welding process will also have a great impact on the actual welding result. The characteristics of laser cladding machine and laser welding machine are as follows:
Movement characteristics: movement accuracy, repeatability, and movement speed.
Help gas: shape, aperture, gas variety, flow, pressure, angle, distance.
When using a laser welding machine for the first time, you may encounter various problems. How to identify the cause of the problem and how to solve these problems is also a very important part of the laser process.
Generally speaking, if there are continuous poor welding in the same part to be laser welded, it is probably because the workbench and clamps have problems. At this time, it is necessary to deal with the problem from the fixture and workbench; if the incoming batches are separated, welding processing Poor, probably due to incoming materials, it is necessary to check and exchange incoming materials or change the laser welding machine waveform setting process conditions for handling; if there are accidental weld penetration and false welding signs, you can check the energy stability of the welding machine or the workbench and fixture Is there a problem? Be careful during the operation of the laser welding machine.
