Welding process for laser cutting Laser
laser cutting machine is mostly through the numerical control program to contr Ol the operation of the. Laser cutting processing methods are widely used, almost all of the material can be cut, including the cutting of thin metal plate
. It can also be used in the field of automobile manufacturing, such as the space curve cutting of the car top window, the laser cutting all kinds of complex body sheet and curved surface parts. Laser cutting technology can also be used in the aerospace field, which is mainly used for the cutting of special materials such as, titanium alloy, aluminum alloy, nickel alloy, chromium alloy and composite materials, plastic ceramics, and quartz, etc..
in addition to the high hardness and brittleness of the material, the material can also be cut and processed, for example, cloth Paper, plastic, rubber, etc.., The main advantages of
laser welding are:
1 laser welding speed is fast the depth, is big, the deformation is small. Can be welded at room temperature or under special conditions, and the equipment is simple and easy to be welded. For example, the laser beam will not be offset by the electromagnetic field, the laser can be applied in the air and some gas environment, and can be welded by glass or transparent material. Laser focus, high power density, high power devices in the welding, the depth to width ratio of up to 5:1, up to 10:1.
can be welded refractory materials 2 such as titanium quartz, etc., and, can apply to the opposite sex, the effect is good. For example, the two Kinds of different properties of copper and tantalum materials welded together, the pass rate of nearly one hundred percent.
also be micro welding. 3 can Laser beam after focusing can get very small spot, and precise positioning can be used in automated mass production of micro and small component of group welding, for example, integrated circuit lead, hairsprings display, tube electronic gun assembly due to the adoption of the laser welding, not only the production efficiency rate, high and small heat affected Zone, solder joints with and without pollution, greatly improving the welding quality.
laser welding can be difficult to close to the site, the implementation of non contact remote welding, with great FLEXIBIL Ity. in the YAG laser technology, optical fiber transmission technology is used to make the laser welding technology has been more widely used. The laser beam is easy to realize the light beam in time and space, and can be processed at the same time and multi station processing, which provides the condition for the more precise welding.
