The Characteristics of Laser Welding Machine
Compared with other traditional welding machine technology, laser welding machine has the following advantages: 1. Laser welding machine belongs to non-contact welding machine, the operation process does not need pressure, the welding machine has fast speed, high efficiency, large depth, small residual stress and deformation, and can be welded at room temperature or under special conditions (such as enclosed space), welding machine. The equipment is simple and does not produce X-ray. 2. Weldable machines, such as refractory materials of high melting point metals, can even be used for welding machines of non-metallic materials such as ceramics and plexiglass. Welding special-shaped materials has good effect and great flexibility. It can be used for non-contact long-distance welding machine for parts that are difficult to approach by welding machines. 3. The laser beam can obtain very small spot by focusing. Because it is not affected by magnetic field and can locate accurately, it can be used in micro-welding machine, which is suitable for assembling welding of micro-and small-sized workpieces produced in large quantities. 4. Laser beam is easy to realize beam splitting according to time and space. Laser beam can be transmitted to several workstations by switching device. Therefore, multi-beam simultaneous processing and multi-station processing can be realized, which provides conditions for more precise welding machine. 5. Laser welding machine belongs to non-contact processing, laser marking laser marking machine has no tool wear and tool replacement problems, at the same time, it does not need to use electrodes, so there is no fear of electrode pollution or damage, and it is easy to automate high-speed welding machine. It can also be controlled by digital or computer. However, laser welding machine also has some limitations: first, the cost of laser and related systems is high, and the investment of disposable equipment is large. Secondly, in the process of welding machine, it is required that the assembly accuracy of welding machine is high, and the position of beam on the workpiece should not be significantly offset. In addition, the thickness of the welder is more difficult than that of some high reflectivity metals of the electron beam welding machine.
