Engineering FAQ

Technical & Procurement Questions

Direct answers from our senior laser applications engineers and quality inspectors.

Does Lumicision perform electric vehicle (EV) battery welding and copper-to-aluminum busbar laser welding?

Yes. We specialize in EV battery welding using automated, robotic, and high-frequency galvanometer wobble fiber laser systems. Pure copper reflects up to 95% of infrared light at room temperature; our spatial beam oscillation creates a stable keyhole that suppresses intermetallic brittleness and porosity when welding copper to aluminum, nickel, or steel battery terminals with a <0.1mm heat-affected zone (HAZ).

Can laser cutting replace hard stamping dies for EV prototype and mid-volume busbars?

Yes. Stamping dies for complex multi-hole EV battery busbars often cost $30,000–$80,000 and take 8–14 weeks to tool. Lumicision cuts and welds directly from native CAD files with zero tooling investment and ±0.002" (50 microns) repeatability, turning around design revisions in 24 to 48 hours.

What quality and engineering certifications back your automotive and EV battery work?

Lumicision has been continuously ISO 9001:2015 certified for 9 years (nearly a decade) and holds a Certificate of Authorization (C of A) from Professional Engineers Ontario (PEO) for professional engineering and design in Ontario—supporting full First Article Inspection Reports (FAIR) and EN 10204 3.1 mill test reports.

How do you prevent oxidation and ensure high electrical conductivity on cut and welded EV battery components?

We execute all copper and aluminum cutting under high-purity, high-pressure Nitrogen (N2) assist gas and perform EV battery laser welding under coaxial Argon/Nitrogen shielding. This prevents resistive oxide scale and yields bright, mirror-like edges and low-resistance weld joints.
