Laser Welding Service

Our laser welding service allows you to send us small batches of parts for welding. We will develop a laser welding process for you and test the laser process on coupons and samples to make sure it meets your specifications. Then, we will weld your parts.

With this service, you can:

Validate laser welding in your manufacturing process
Produce a small batch for prototyping or preproduction
Meet a short-term surge in production.
Start producing right away while waiting for a laser welding machine order

Battery Laser Welding

Laser welding is used in the battery industry for its speed, precision, and consistency. It is ideal for cylindrical and prismatic cells to ensure a repeatable level of quality for hundreds or even thousands of welds.

Robot-Assisted Busbar Laser Welding (patent pending)

Automated Busbar Laser Welding

Laser welding is used to automate cell-to-busbar connections. Multiple SCARA robots hold and move dynamic clamping tools to ensure zero gap. The force applied to the busbar is monitored using pressure sensors. A vision system is also used to detect the position of each cell and compensate for positioning variations. Laser weld monitoring provides immediate feedback on weld quality.

Same Quality & Cycle Time from Prototype to Production

We perform laser welding using the same equipment you will use in production. This ensures that the welds produced during prototyping will be of the same quality during production. The laser welding process will also be of the same speed.

Zero Gap with Custom Tooling

Based on your specifications, Laserax develops custom tooling and clamping tools to achieve zero gap between welded surfaces. Pressure sensors are used to ensure the right pressure is applied on the welds.

Weld Quality Validation

Laserax can use a range of tests and measurements to validate weld quality. These include cross-section images (SEM), mechanical resistance (force tester), electrical resistivity (four-wire Kelvin measurement), laser weld monitoring data (light reflection), depth of penetration (SEM), and aging tests.

Laser Welding Process Development

The development of a custom laser welding process is an integral part of our laser welding service. We will validate feasibility on coupons, optimize the process with you on samples to meet your requirements, then laser weld a batch of your product.

Laser Welding: The Alternative to Ultrasonic Bonding

Laser welding is faster than ultrasonic wire bonding. When making cell connections in battery modules, cylindrical cells can be directly welded to busbars, eliminating the need for wires and reducing the number of welds by half.

Tab Welding Methods

Because it is faster and ensures consistent results, laser welding is increasingly used to make tab-to-terminal connections, replacing methods like ultrasonic bonding, resistance welding, and micro TIG welding.
