Laser welding at reduced pressure is characterised by a range of advantages: With the same laser performance, the achievable welding depth is approximately doubled in comparison to welding at normal ambient pressure. The weld profile is also more parallel-sided and the formation of the nailhead reduced.

The reduced pressure also dispenses with the use of inert gas, and the melt can de-gas more easily, thereby reducing the pore density. All effects therefore contribute to the improvement of the quality of the weld seam!

The LASVAC PL series has been developed on the basis of the proven and established PTR cycle system. This enables the coupling of the solid state laser by laser fiber.
The main area of application is the mass production of components with radial and/or axial weld seams. Due to the flexibility of the system, the LASVAC PL series is also the ideal tool for a changing component range. If workpieces or production conditions change at a later time, the modular design of the LASVAC PL series enables the system to be adapted and upgraded as necessary.
