Laser Welding System for Pillow Plates

Feel free to contact us on industrial robots and we will gladly answer any of your questions.

Product Overview

This system is purpose-built for manufacturing pillow plates used in heat exchangers, tank jackets, and cooling plates. It utilizes precision laser welding to join two metal sheets, which are later inflated to form internal flow channels with excellent heat transfer performance and mechanical durability.

The drag-type welding structure ensures accurate weld paths and smooth, continuous seams without burrs—eliminating the need for post-processing. A proprietary welding process minimizes spatter and protects surface quality, while the shielding gas plate ensures the weld retains its natural metallic appearance.

Proven in the Chinese market with over 90% share, this system is a reliable and cost-effective choice for pillow plate fabrication.
