Using a 4-in-1 Fiber Laser Welding Machine: Method Guide

Overview

A 4-in-1 fiber laser welding machine typically combines four functions: laser welding, cleaning, cutting, and marking in one system. Here's a comprehensive guide to using this multifunctional equipment.

Setup Procedure

1. Machine Preparation

• Ensure proper grounding and stable power supply (typically 220V/380V)

• Install the cooling system (water chiller) and check coolant levels

• Connect the exhaust system for fume extraction

2. Software Configuration

• Install the control software on your computer

• Connect to the machine via USB or Ethernet

• Calibrate the laser head focal length

Operation Methods

For Laser Welding

1. Select welding mode in the control software

2. Set parameters:

• Power (typically 200-1000W)

• Pulse frequency (1-1000Hz)

• Pulse width (0.1-20ms)

• Welding speed (0.1-10m/min)

3. Prepare materials (clean surfaces, proper fit-up)

4. Perform test weld and adjust parameters

5. Execute full welding operation

For Laser Cleaning

1. Switch to cleaning mode

2. Adjust parameters:

• Cleaning power (lower than welding)

• Scanning speed

• Spot overlap rate

3. Select appropriate cleaning pattern (linear, area, etc.)

4. Perform cleaning operation with proper PPE

For Laser Cutting

1. Select cutting mode

2. Set cutting parameters:

• Focus position

• Assist gas type/pressure (N₂ or O₂)

• Cutting speed

3. Import or create cutting pattern

4. Perform test cut and adjust as needed

For Laser Marking

1. Select marking mode

2. Create/import marking design

3. Set parameters:

• Marking speed

• Line spacing

• Power level

4. Perform marking operation

Safety Precautions

• Always wear laser safety goggles

• Never look directly at the laser beam

• Ensure proper ventilation

• Keep flammable materials away

• Follow lockout/tagout procedures for maintenance

Maintenance

• Daily: Clean lenses and mirrors

• Weekly: Check optical path alignment

• Monthly: Inspect cooling system and cables

• Annually: Full system calibration by technician

Troubleshooting

• Weak laser power: Check fiber connections, replace consumables

• Poor weld quality: Recalibrate focus, adjust parameters

• Overheating: Check chiller operation, clean filters
