We laser welded bent tabs to bus bars to maximize the contact point for an even current flow.
Copper welding is notoriously difficult due to the material’s extreme reflectivity and rapid thermal conductivity. Where standard welding methods fail or cause massive heat distortion, our specialized laser welding capabilities deliver precise, repeatable results.
This is a great example of how mobile laser welding systems like the Alpha Laser AlFlak can be used for a project of virtually any shape or size.
Benefits:
-
Overcoming High Reflectivity: We utilize optimal laser wavelengths and power modulation to break through copper’s reflective barrier instantly, establishing a stable keyhole without damaging surrounding components.
-
Minimal Heat-Affected Zone (HAZ): Our process delivers high-energy density at extreme speeds. This localizes the heat strictly to the joint, protecting sensitive nearby electronics, insulation, or battery cells from thermal damage.
-
Seamless Material Fusion: Whether joining flat components or complex geometries like bent tabs to busbars, our systems ensure deep, consistent penetration with minimal porosity and maximum structural integrity.
-
Low-Resistance Connections: We achieve pure, void-free metallic bonds that guarantee maximum electrical conductivity and zero bottlenecks for high-current applications.
