The principle of laser welding machine

Laser welding is one of the important aspects of laser materials processing technology,often referred to as laser welding, laser welding machine, according to their work often can be divided into the laser die burn machine (manual Welding machine), automatic laser welding machine laser spot welding, fiber-optic transmission laser welding machine, light welding is the use of high-energy laser pulse to a small region of local heating on the material, internal diffusion of laser radiation energy by heat transfer-oriented material, the material melted to form a specific bath in order to achieve the purpose of welding.


The main features of laser welding machine.

The 1970s is mainly used for welding thin-walled materials and low-speed welding, the welding process is a thermal conductivity type, the laser radiation heating the surface, the surface of the heat through the heat transfer-oriented internal diffusion control the width of the laser pulse energy, peak power and repetition rate

Other parameters so that the workpiece to melt, the formation of specific bath. Because of its unique advantages, have been successfully applied in the micro, precision welding of small parts. The emergence of high-power CO2 and high-power YAG lasers, has opened up new areas for laser welding. To obtain deep penetration welding, to the effect of holes as the theoretical basis and increasingly widely used in machinery, automobile, steel and other industrial areas.

Laser welding and other welding techniques, the main advantages of laser welding is:

, speed, depth, small deformation.

<2>, at room temperature or under special conditions, welding, welding equipment device is simple. For example, the laser through the electromagnetic field, the beam will not be offset; laser welding can vacuum, air and a gas environment, and through the glass or transparent material on the beam welding.

<3>, the welding of refractory materials such as titanium, quartz, and welding the opposite sex material to good effect.

<4>, laser focused, high power density, the welding of high-power devices, the aspect ratios up to 5:1 up to 10:1.

<5> can be micro-welding. Available by focusing a small laser beam spot, and can precise positioning can be applied to the automated production of large quantities of micro, small parts welding.

<6>, welding hard-to-reach parts of the implementation of long-distance non-contact welding, a lot of flexibility. In recent years, the YAG laser processing technology uses a fiber optic transmission technology, access to a wider range of promotion and application of laser welding technology.

<7>, the laser beam is easy to realize the beam splitter according to time and space, at the same time processing of multi-beam and multi-bit processing, provided the conditions for more precise welding
