Direct answers from our senior laser applications engineers and quality inspectors.
How does Lumicision weld highly reflective copper without spatter or porosity?
Pure copper reflects up to 95% of infrared laser light at room temperature. We overcome this optical barrier by utilizing multi-kilowatt fiber lasers equipped with high-frequency galvanometer wobble heads. The beam oscillating path creates a stable keyhole that captures the laser energy efficiently, producing dense, porosity-free weld seams down to 0.1mm width with an ultra-narrow heat-affected zone (HAZ).
Can laser cutting replace hard stamping dies for EV prototype busbars?
Yes. Stamping dies for complex multi-hole busbars often cost $30,000–$80,000 and take 8–14 weeks to tool. Lumicision cuts directly from native CAD files in minutes with zero tooling investment. When battery engineers modify terminal positions or mounting tabs, new revisions are cut and formed in 24 to 48 hours.
What turnaround time can Lumicision support for Tier-1 line-down emergencies?
We maintain dedicated 24/7 production shifts and on-floor inventory of C11000 copper, 6061-T6 aluminum, and high-strength steels. In line-down or urgent prototype scenarios, we deliver completed, inspected parts within 24 to 48 hours to Toronto, Vaughan, Markham, and Midwestern US automotive assembly plants.
How do you prevent oxidation and ensure high electrical conductivity on cut edges?
We execute all copper and aluminum cutting under high-purity, high-pressure Nitrogen (N2) assist gas. This shields the molten cut kerf from ambient oxygen, preventing resistive cuprous oxide scale and leaving bright, mirror-like edges that meet ASTM conductivity benchmarks and solder/weld cleanly.
