The fiber transmission YAG laser welding machine is mainly used for welding thin metal plates with a thickness of 0.5mm or less. Such as: stainless steel, aluminum alloy, steel, aluminum, gold, silver and other metals in the industries of electronic components, lithium batteries, medical equipment, mobile phone communications, glasses and watches, welding of the same material and welding of some dissimilar materials.

Principle: YAG laser welding is to weld the workpiece with high-energy pulsed laser. It uses pulsed xenon lamp as the pump source and YAG as the working material for producing laser. The laser power supply first pre-ignites the pulsed xenon lamp, and discharges the pulsed xenon lamp through the laser power supply, so that the xenon lamp generates a light wave of a certain frequency and pulse width. The light wave irradiates the laser crystal through the condensing cavity to excite the crystal to generate laser light, and then generates a wavelength after passing through the resonant cavity It is a 1064nm pulsed laser, which is transmitted and focused through an optical fiber and radiated to the surface of the workpiece to melt the workpiece locally to achieve welding.

Advantages and characteristics:

1. Spot welding, butt welding, stitch welding and sealing welding can be performed on the workpiece;

2. Fast welding speed, high aspect ratio, small heat-affected zone and small deformation during welding;

3. The welding seam is smooth and beautiful, no need or only simple treatment after welding;

4. Multi-beam welding can be integrated to realize energy splitting and time splitting;

5. Optional CCD camera monitoring system, accurate positioning, real-time observation of the welding process;

6. It can weld complex tracks such as planes, circles, and arcs;

7. Integrate energy negative feedback laser control technology to realize the consistency of welding effect from beginning to end;

8. Integrate arbitrary waveform control technology, which can accurately control the welding point formed by each pulse energy to achieve the best welding effect.
