How to Choose the Right Laser Welding Machine?

First of all, we need to understand what types of laser welding machines there are what are the main application industries of each type of laser welding machine; secondly, we need to understand the key points of choosing a laser welding machine; finally, choose a machine that suits you according to your needs and budget.

1. Classification by type of laser:

A. Fiber Laser Welding Machine:
Features: High Beam Quality, High Electro-Optical Conversion Efficiency (Up To 30%), Simple Maintenance, And Precision Welding.
Applications: Auto Parts, Batteries (Such As Power Battery Ear), 3C Electronics, Etc.

B. YAG laser welding machine:

Features: Pulse Or Continuous Output, Wavelength 1.06μm, Suitable For Spot Welding And Thin Wall Materials, But Low Energy Efficiency.
Application: Electronic Components, Jewelry, Small Metal Parts Welding.

C. Mixed Laser Welding Machine:
Features: Combined With The Advantages Of CO₂ And Fiber Laser, The Beam Quality Is Good, Suitable For High Power Welding.
Application: Automobile Industry, Heavy Machinery.

D.Semiconductor laser welding machine:

Features: Small Size, Low Cost, But Poor Beam Quality, Suitable For Scenes With Low Precision Requirements.

2. Classification by mode of operation:

A. Pulsed laser welding machine:
Features: Through short pulse output energy, suitable for precision spot welding or thin material welding (such as electronic components, gold and silver jewelry).

B.Continuous laser welding machine:
Features: Continuous output laser, suitable for deep fusion welding or high speed welding (such as automotive body welding).

3. Classification by degree of automation:

A. Manual laser welding machine:
Features: flexible operation, manual positioning is required, suitable for small batch maintenance or experiment.

B. Automatic laser welding machines:
Features: integrated manipulator or CNC system for assembly line production (such as automotive industry).

-Galvo Laser Welding Machine: High Speed Scanning Welding, Suitable For Precision Patterns (Such As Battery Posts).
-Robot Laser Welding Machine: Six-Axis Robotic Arm For Complex Three-Dimensional Paths (Such As Body Welding).

4. Classification according to welding process:

A. Conduction welding:
Features: laser melts the surface of the material, no deep melting hole, suitable for thin plates, precision welding.

B. Deep fusion welding (keyhole welding):
Features: high power laser vaporization of metal to form deep melting holes, suitable for thick plates (such as ships, aerospace).

5. Classification By application filed:

A. Power battery laser welding machine:
Requirements: high precision, low thermal effect (such as lithium battery tabs, sealing nail welding).

B. Auto parts welding machine:
Application: gearbox gears, door hinges, etc.

C.Electronic precision welding machine:
Applications: sensors, PCB components, micro connectors.

D.Medical equipment welding machine:
Requirements: sterile, pollution-free (such as surgical instruments, implant packaging).

6. Special categories:
A. Composite welding machine:
Features: laser + arc (MIG/TIG) composite, improve efficiency and depth of fusion (such as thick plate welding of ships).

B.Remote laser welding machine:
Features: Welding at a distance with a long focal length lens reduces equipment movement (such as car roof welding).

Then How to Choose the Right Laser Welding Machine? --Selection points:
Material: high reflectivity metal (copper, aluminum) requires optical fiber or green laser.
Thickness : thin material (<1mm) pulse or low power continuous laser; thick plate needs kilowatt high power.
Accuracy: the electronic industry needs a galvanometer or YAG; large structural parts can be selected for a robot integration system.

Different types of laser welding machines have their own advantages and disadvantages, which need to be comprehensively considered according to the material (thickness, reflectivity), process requirements (speed, accuracy) and budget. With the progress of technology, its application scope is expanding from industrial manufacturing to high-end fields such as microelectronics, bio-medical and so on.
