What is Galvanometer Laser Scanner？
The core is to change the propagation direction of the light beam by controlling the deflection angle of the reflector.
The main features include: ultra-high response speed, high accuracy and good repeatability, and limited deflection angle range (but suitable for most scenarios).
Galvanometer Laser Scanner is mainly used in high-end application fields such as high-power laser welding, laser cutting, laser cleaning, laser drilling, and new energy lithium battery welding.
The Application of the Galvanometer Laser Scanner
The Galvo Laser Head is the core component of the battery laser welding machine. With its high precision and microsecond response, it is suitable for switching between different batteries. It is mainly suitable for welding of power battery pole pieces and energy storage battery shells.
The Galvo Laser Head is the key part of the laser marking machine. It adjusts the laser path through the computer-controlled reflector to achieve high-speed and accurate marking. It has the characteristics of fast response, high precision, and adaptability to multiple materials, and is widely used in electronics, automobiles and other industries.

High precision requirements: Scenarios where tab spacing is less than 5mm and shell weld width is ≤ 0.1mm.
Mass production: When the daily output of a single production line exceeds 100,000 batteries, the efficiency advantage of galvo welding is significant (e.g., 0.1 seconds per set of tabs for welding).
The key distinction is beam positioning:
Galvanometer laser scanner uses high-speed galvanometer mirrors to steer the laser beam directly (no mechanical movement of the head/workpiece).
A handheld laser welding gun requires moving the tool or workpiece to align the beam.
Galvanometer laser scanner offers faster, more flexible welding for complex patterns.
