Specialty Services

Mechanized Laser Welding

Fiber laser for battery materials and applications — power bus (bus bar welding), IP-6X sealing, FPC flexible circuit, and all three form factors: cylindrical, prismatic, and pouch.

Mechanized process control for repeatable welds — not lights-out automation

Advance Laser Welding Workflows with Mechanized Process Control

Prime Energy's laser-welding services apply to approved external terminals, tabs, busbars, interconnects and pack-level components. Prime Energy does not open sealed cells or modify their internal chemistry.

We help engineering teams and assembly programs develop laser welding processes that go beyond the weld itself. That includes mechanized movement, part positioning, fixture coordination, weld path logic, parameter control, and programming on our cells that supports repeatable battery assembly.

From power-bus and bus-bar joining to IP-6X enclosure sealing and FPC flexible-circuit work, the same fiber-laser process covers cylindrical, prismatic, and pouch packs.

Comprehensive Laser Welding and Mechanized Programming Support Built for Battery Module and Pack Assembly

Our approach helps teams create cleaner, more repeatable welding processes by connecting weld development with mechanized process strategy, custom programming, part handling, and process validation—within the external interconnect and pack-component scope described above.

Laser Weld Process Development

Support weld strategy for approved external terminals, tabs, busbars, thin metals, interconnects, and battery pack subassemblies with attention to consistency, fit-up, and part sensitivity.

Standards Customers Often Prepare For

Prime Energy does not certify packs, modules, or systems. We can help you prepare documentation, test readiness, and design decisions for a third-party certification program. Listing a standard here does not mean we perform that lab test or hold that listing.

  • UL 1973 — Packs and systems used in stationary energy storage and motive auxiliary power applications.
  • UL 2580 — Packs and modules used in electric vehicle applications.
  • UL 2271 — Batteries used in light electric vehicle applications such as smaller mobility platforms and support vehicles.
  • IEC 62133-2 — Portable sealed secondary cells and batteries used in portable applications.
  • IEC 62619 — Secondary cells and batteries used in industrial applications, including many larger pack and stationary use cases.
  • IECEE CB Scheme — A global scheme for accepting IEC test reports. We can help you prepare; a third-party issues the report.
  • UL 9540 — System-level listing path for complete energy storage systems and equipment, often relevant when a pack is part of a larger ESS.
  • UL 9540A — Fire test method commonly used to evaluate thermal runaway fire propagation behavior in battery energy storage systems.
  • UN 38.3 — Transport testing required for shipping cells and batteries; this is a transportation requirement rather than a product safety listing.
