Welding Methods

The variety of welding techniques allows different requirements to be met. From classic MIG/MAG or TIG welding to high-precision laser beam welding, welding enables the production of durable, thermally efficient, and mechanically robust cooling solutions.

COOLTEC Focus Area: Laser Beam Welding

In laser beam welding, a focused laser beam is directed onto the workpiece to precisely fuse materials together.

Benefits:

  • High precision due to concentrated heat zone

  • Minimal thermal expansion in adjacent areas

  • Narrow, deep-penetrating weld seams

  • Suitable for materials such as aluminum or copper

Thermal Performance & Stability in Welding

When welding heat sinks and liquid cooling plates, the metallic connection between components ensures efficient heat conduction and high mechanical stability. Copper tubes provide particularly effective heat dissipation, while aluminum is preferred for its low weight and good corrosion resistance.

Through precise welding techniques such as laser beam welding, even complex geometries can be joined accurately without thermal stress affecting adjacent areas. The result is customized, durable cooling solutions suitable for both prototypes and series production.
