Laser Welding Machines for Battery Cells, Modules & Packs

Find the right machine configuration for your connection materials, joint design and production requirements.

  • Choose equipment around your battery design
  • Review sample welding requirements before selection
  • Plan tooling, positioning and quality checks together

Which Welding Configuration Fits Your Product?

Start with your battery drawing, connection materials and target output. The right choice depends on the working area, weld access, positioning method and complete production cycle.

Gantry welding machine

Gantry Welding Machine

Consider a gantry configuration around your part dimensions, weld positions and fixture layout. Review travel, joint access and the loading method against your product drawing.

High-speed galvanometer welding machine

Galvanometer Welding Machine

Review beam scanning for weld locations within a defined working field. Confirm field size, joint access and the complete product cycle before selecting a configuration.

3-Axis Laser Welding Machine

3-Axis Laser Welding Machine

Review three-axis movement for programmed welding paths. Confirm axis travel, fixtures and product changeover requirements for the battery models you intend to manufacture.

Plan the Machine, Tooling & Quality Checks Together

Match Your Battery Design

Review your battery dimensions, connection layout and joint access. Define the working area and fixture requirements before confirming the machine configuration.

Plan Product Changeovers

Identify the battery models you intend to manufacture. Clarify which changes require new fixtures, positioning adjustments or a different welding program.

Agree on Acceptance Criteria

Define how the connection will be evaluated. Discuss weld appearance and, where applicable, strength, electrical resistance or section checks before acceptance.

Positioning, Welding & Process Verification

Find the Right Welding Position

Reliable joint access starts with the right fixture and positioning method. Review what the proposed camera and sensing systems can measure, which corrections they support, and how they work with your part tolerances.

Confirm before selection:

  • The features used to locate each welding position
  • Any required position or height correction
  • Fixture, calibration and setup responsibilities

Review the Welding Process Before Finalizing the Machine

Material, coating, thickness and joint design determine what needs to be evaluated. Share your connection details first so the equipment scope and any required sample trials can be discussed together.

  1. Share your application: drawings or clear photos, materials, thicknesses and target output.
  2. Agree on evaluation criteria: identify the appearance, strength or electrical checks relevant to your connection.
  3. Review the findings: discuss the results of any agreed sample trials and the implications for tooling, positioning and the full production cycle.

Questions Before Starting Your Battery Project

Not sure about laser power, product compatibility or cycle time? These questions help define the application before a machine is recommended.

Power selection depends on the materials, thicknesses, joint design and production requirements.

Share these details first so the proposed power and welding process can be assessed together.

That depends on the working range, tooling, positioning method and validated processes.

Define the intended product range and the changeover work before confirming the configuration.

Production cycle time includes loading, positioning, welding, inspection and unloading.

The useful comparison is the complete cycle for your product under agreed operating conditions.

Start with a drawing or clear photos, connection materials and thicknesses, and your target output.

Add any requirements for automation, inspection or integration with existing equipment.
