1500W Fiber Laser Mould Repair Welding Machine

1.1 Summary

Laser welding is an advanced welding method and an important application of laser material processing technology.
This equipment is mainly designed for thin-walled materials and precision parts, using a heat conduction welding process.

Laser radiation heats the workpiece surface, and the heat is conducted inward. By controlling pulse width, energy, peak power, and repetition frequency, the workpiece melts to form a molten pool.

Applicable welding methods:

1. Spot welding

2. Butt welding

3. Overlay welding

4. Sealing welding

Key features:

1. High depth-to-width ratio, narrow weld seams, small heat-affected zone, minimal deformation

2. Fast welding speed; smooth and aesthetic weld seam

3. No or minimal post-processing required

4. High weld quality, no porosity

5. Precise control, high positioning accuracy, easy automation

1.5 Working Environment Requirements

1. Ambient temperature: 5℃–35℃ (air conditioning recommended)

2. Humidity: 40%–80%, no condensation (dehumidifier recommended)

3. Power supply fluctuation: <5%; for areas with >5% fluctuation, install automatic voltage stabilizer

4. Foundation vibration: amplitude <50 μm; acceleration <0.05 g; avoid large stamping machines nearby

5. Air pressure: 86–106 kPa

6. Environment:

• No strong electromagnetic interference; avoid radio transmitters or relay stations

• Dust-free and smoke-free workspace; avoid metal polishing powder environment

• Anti-static flooring recommended; equipment grounded

7. If ambient temperature <0℃, add antifreeze to water; drain water when equipment is not in use

1.6 Machine Structure and Working Principle

The welding machine consists of laser power supply, optical system, cooling system, and 3D worktable.
It uses high-energy pulsed laser for welding.

Working principle:

1. Fiber laser emits pulsed laser with 1080 nm wavelength

2. Laser passes through transmission, beam expansion, and focusing to act on the workpiece

3. Frequency and pulse width are controlled by microcontroller to adjust power and energy for precise welding
