Compared with other traditional welding techniques, laser welding has the following advantages:

1, the laser welding is a welding of the non-contact type, the operating process without pressure, welding speed, high efficiency, large depth, the residual stress and the deformation is small, can be welded at room temperature or under special conditions (such as a closed space), the welding The equipment is simple, does not produce X-ray apparatus.

2, welding refractory material, such as a high melting point metal, and even can be used for non-metallic materials such as ceramics, plexiglass and other welding of profiled Welding Material, to good effect, and has a great deal of flexibility, can be difficult to access for welding parts of the purposes of the non-contact remote welding.

3, the laser beam by focusing a small spot can be obtained precise positioning unaffected by magnetic fields and can, therefore, micro welding, suitable for the automated production of large quantities of micro, small workpiece assembly welding.

4, the laser beam is easy to realize spectroscopic beam by time and space, can switch means transmitting a laser beam held multiple workstations simultaneously processing of a multi-beam, and multi-bit processing, therefore, can be performed, provided the conditions for more precise welding.

5 is a non-contact processing, no tool wear and tool exchange and other issues, at the same time, without the use of electrodes, so there is no electrode contamination or damage concerns, and easy to automate high-speed welding, laser welding. Also can be digital or computer control. However, laser welding also there are some limitations:

First, the high cost of lasers and their associated systems, disposable equipment investment.

Secondly, during the welding process, the Welding Assembly of high precision, and the position of the beam on the workpiece not have a significant offset.

Further, the weld thickness than the electron beam welding small, welding some of the high reflectance of the metal is still relatively difficult.
