automated laser welding machine

Equipment principle

The laser welding machine is apply a pulsed laser with a wavelength of 1064 nm generated by a laser. After being expanded, reflected and focused, the surface of the workpiece is radiated, and the surface heat is diffused to the inside through heat conduction. The width, energy, peak power and repetition of the laser pulse are precisely controlled by digitization. Parameters such as frequency, the workpiece is melted to form a specific molten pool, thereby achieving laser welding of the workpiece, and completing precision welding that cannot be achieved by conventional processes.

1. Laser welding can achieve spot welding, butt welding, overlay welding, sealing welding, etc. for thin-walled materials and precision parts.

2. The laser power is large, the weld has a high aspect ratio, the heat affected area is small, the deformation is small, and the welding speed is fast.

3. The weld quality is high and flat, no porosity, and the toughness of the material after welding is at least equivalent to the parent material.

4. Humanized design, LCD display, centralized button operation is simpler.

5. Four-dimensional ball screw workbench adopts imported servo control system and optional rotary table. It can realize automatic welding such as spot welding, straight line welding and circumferential welding. It has wide application range, high precision and fast speed.

6. The current waveform can be adjusted arbitrarily, and different waveforms can be set according to different welding materials, so that the welding parameters and welding requirements are matched to achieve the best welding effect.
