Four axis laser welding machine

Equipment introduction

The four axis linkage laser welding machine is a laser welding machine for the development of precision welding industry, with high magnification system, by the majority of users. The latest device uses a constant voltage source mode, with a touch screen and a button type can be selected, the power system waveform can be adjusted, the optical path system through optimization, light path stability, energy constant. The external circulation water uses the Japanese import compressor, the whole machine adopts the military grade refrigeration water tank, the outlook is beautiful, the effect is first-rate.

Pulsed laser power supply is specially designed for pulsed Nd:YAG laser power supply, the use of switching power supply, internal control by single-chip microcomputer. The laser output power, frequency and pulse width are selected through the touch mode operation panel. The laser pulse waveform and parameters are programmed by the user to match the welding parameters and the welding requirements to achieve the best welding effect. Therefore, it can meet the needs of almost all metals.

Laser processing principle

Laser processing principle: laser produced by the laser through a series of processing, the lens focus after the energy is highly concentrated in a very small range, if the material is processed to absorb the laser better, then the material will be irradiated area because of the absorption of the laser energy and rapid heating. Depending on the nature of the material (such as the melting point, boiling point, chemical changes in temperature), the workpiece will occur a series of physical or chemical changes, such as melting, gasification, generating oxide, color, etc.. This is the principle of laser processing.

Advanced processing mode, high efficiency

Compared with the traditional mechanical processing, the focused laser is like a very thin invisible tool, the surface of the object to the point by point of "burn", which is characterized by no contact with the workpiece, mechanical extrusion or mechanical stress, and therefore will not change the physical properties of processed products, due to the size of the laser focusing is very small, small heat affected area, processing fine, so that some conventional methods can not be achieved.

Laser welding principle

Four axis laser welding machine, which is used to focus on the high energy pulse laser for the purpose of metal melting to carry out welding. By the pulsed xenon lamp as pump source, laser power supply controlled by a microprocessor, for the xenon lamp simmer under closed loop control of the discharge, forming a certain pulse width, a certain frequency, energy curves of the pulse wave and the light gathering cavity together to Nd: YAG crystal, laser crystal luminescence, again after a resonant cavity, a 1064 nm pulsed laser, the pulse laser through the beam expander, reflection, focusing on the metal surface, form molten pool, so as to achieve purpose of welding.
