What Applications Are Best Suited for a Galvanometer Laser Welding Machine?

A Galvanometer Laser Welding Machine (also known as a scanner welding system) offers high speed and precision—but it’s not ideal for every job. Understanding its strengths helps buyers determine if it fits their production needs.
 
Ideal for Small, Flat, High-Volume Parts
 
This type of system uses fast-moving mirrors to steer the laser beam across a fixed work area, eliminating the need for robotic arms or moving stages. As a result, it excels in applications requiring:
 
Rapid spot or seam welding on thin materials (typically under 2 mm)
 
Minimal heat input to avoid warping sensitive components
 
High repeatability with short cycle times
 
Common use cases include battery tab welding in EVs, hermetic sealing of sensors and medical devices, electronic enclosures, and precision automotive lighting assemblies.
 
Not Suitable for Large or 3D Components
 
The main limitation is the working field—usually a flat plane between 100×100 mm and 300×300 mm—and shallow depth of focus (often ±1 mm). Parts that are large, curved, or have significant height variations fall outside this range, leading to defocusing and inconsistent welds. For such geometries, a robotic or CNC-guided laser system is more appropriate.
 
Key Considerations Before Buying
 
When evaluating a Galvanometer Laser Welding Machine, ask:
 
Are your parts flat and within the scanner’s field of view?
 
Can your fixturing hold parts consistently at the correct focal height?
 
Do you need vision alignment or dynamic focus to handle real-world tolerances?
 
In summary, a Galvanometer Laser Welding Machine is a strong solution for high-speed, precision welding on small, planar components. But it requires careful matching to your part geometry and production requirements. Always validate with actual production samples before committing.
