The main characteristics of the laser welding technology

Laser welding machine compared with other conventional welding machines, laser welding has the following advantages:
1. Laser welding is a non-contact welding operation process without pressing, welding speed, high efficiency, depth, residual stress and deformation of small, can be welded (such as an enclosed space) at room temperature or special conditions, welding equipment installation simple, does not produce X-rays.
2. Can welding of refractory metals such as refractory materials, ceramics and even can be used, such as welding, plexiglass and other non-metallic materials, shaped materials for welding, works well, and has great flexibility for welding difficult to access the site of the purposes of the non-contact remote welding.
3. The laser beam obtained by focusing a small spot, due to the influence of the magnetic field is not capable of precise positioning, therefore, it can be micro-welding, welding for high-volume automated production of micro, small workpiece.
4. The laser beam is easy to achieve time and space by the beam splitter, the device can switch the laser beam delivery For more workstations, therefore, capable of multi-beam processing and multi-bit processing, a more sophisticated welding conditions.
5. The result is a non-contact laser welding process, no tools and tool exchange loss and other issues, at the same time, it does not need to use the electrodes, no electrode contamination or damage concerns, and easily automated for high-speed welding. It can also be digital or computer-controlled. However, laser welding, there are some limitations:
First, the laser system and its associated higher costs, greater investment in disposable devices.
Secondly, during the welding process, welding assembly requires high precision, and the beam position on the workpiece requires not significantly offset.
In addition, the welding thickness is smaller than electron beam welding, weld metal has a number of high reflectance is difficult.
