Frequently Asked Questions — EV Busbar & Dissimilar Metal Welding
How does spatial beam oscillation (wobble) laser welding prevent brittle intermetallic compounds when joining Copper to Aluminum?
By oscillating a focused fiber laser beam at high frequency along programmable circular, figure-8, or infinity patterns, our automated and robotic laser welding cells precisely control penetration depth and stir the melt pool. This suppresses brittle Al-Cu intermetallic compound (IMC) layer thickness, yielding ductile, spatter-free laser welds with ultra-low micro-ohm electrical contact resistance.
What EV battery and busbar materials can Lumicision laser weld?
We laser cut and laser weld C11000 (ETP), C10100/C10200 (Oxygen-Free OFHC), and nickel-plated copper busbars directly to 1050, 1100, 3003, and 6061 aluminum EV battery terminals, cylindrical/prismatic/pouch cell tabs, and Hilumin® nickel-plated steel current collectors.
How small is the Heat-Affected Zone (HAZ) near sensitive EV battery cells or electronics?
Our automated pulsed and continuous-wave (CW) fiber laser welding maintains ±0.002" (50 microns) seam placement accuracy with a seam width down to 0.10 mm and a Heat-Affected Zone (HAZ) under 0.10 mm—protecting adjacent lithium-ion cells, glass-to-metal seals, and polymer dielectric insulation from thermal damage.
Can Lumicision supply both the laser-cut copper busbar blanks and the laser-welded EV battery assemblies?
Yes. We vertically integrate 6kW IPG fiber laser cutting of C11000/C10100 copper and aluminum busbars, CNC press brake forming, and automated/robotic spatial beam wobble laser welding under one roof in Richmond Hill, Ontario—backed by 9 years of ISO 9001:2015 certification and a PEO Certificate of Authorization (C of A) for Professional Engineering & Design.
Engineer-Reviewed Fast-Track RFQ
Unlike automated black-box algorithms that reject complex tolerances or overcharge for simple bends, every file uploaded to Lumicision is reviewed by a senior fabrication engineer—with a 24 to 48-hour guaranteed quote response time.
