Welding Technology

We mainly join tube-flange and tube-tube connections manually using several welding processes to produce weld seams of high quality. We are experienced in welding stainless steels of different qualities. Hereby particularly noteworthy are the materials 1.4301, 1.4307, 1.4404, 1.4435, 1.4429, 1.4541 and 1.4571.

According to the component requirements we use different welding processes at VACOM depending on the weld geometry and the component thicknesses.

The emergence of virtual leaks is prevented by welding the components on the vacuum side. If this is not possible, we weld vacuum-tight on atmosphere side (not full connection) or use full penetration welding (full connection). If there are custom-specific higher requirements on the strength of the welded components, we are able to attach additional weld seams for support.

With the used weld processes we are able to manufacture very small but also massive components. Our specific knowledge focuses on highly complex vacuum chambers with a large number of exits and the intersection of several exits which have to be manufactured with low tolerances regarding angularity and a high fitting accuracy. We have a lot of experience in welding temperature-sensitive parts such as electrical and optical feedthroughs. Standardization of the processes and technologies allow us to ensure consistently high quality of all welding processes.

 

Our welding processes are certified according to  ISO 3834-2:2006..

This includes the standardized welding by:

  • Qualified welders
  • Qualified welding supervision staff
  • Certified and regularly calibrated equipment
  • Ensuring the traceability of products, materials etc.
  • Documented processes
  • Permanent quality control
  • Continuous training of welders
  • Internal audits
  • Qualification of welding processes
  • Preparation of welding procedure specifications for reproducible weld seams
  • Permanent monitoring before, during and after the welding process
