Low-distortion and low-energy Laser-Multilayer-Narrow-Gap-Welding for the production of large and thick-walled steel structures (VE-MES)

  • Funding agency: Sächsisches Staatsministerium für Wirtschaft, Arbeit und Verkehr
  • Reference: 100320711
  • Duration: 14.08.2017 – 29.02.2020

In cooperation with the Fraunhofer IWS Dresden, BANG Kransysteme GmbH & Co. KG and ANTARES GmbH, a new automated laser beam multi-layer welding technology for the production of thick-walled (15 to 100 mm) large assemblies for crane and heavy steel construction using a high-power diode laser is being developed.
The contents of the development are the low-distortion welded construction, the heat-minimized welding technology, an industrial welding head and a laser protection device adapted to the process and components.

Development of a new processing head for laser-assisted plasma welding (LuPS)

  • Funding agency: Sächsisches Staatsministerium für Wirtschaft, Arbeit und Verkehr
  • Reference: 100189174
  • Duration: 01.01.2016 – 02.02.2018

The content of the cooperative research project supported by SAB with the Fraunhofer IWS and the TU Dresden is the investigation of a novel laser-assisted plasma welding process in coaxial arrangement.

Within the framework of the project, the scientific basis for the development of a coaxial plasma laser torch is to be developed and the process advantages of the laser plasma process are to be analyzed, in particular the possibilities of substituting cost-intensive laser power by plasma power.

Welding Torch as a Technology Carrier

We are a research company specialized in automated welding processes using laser and plasma arc technologies. The main focus of our business is on high-performance TIG welding technologies for iron and non-ferrous metals, and aluminum. Our torch-developments support the InFocus and ARCLINE® PP high-performance technologies. The se torches stand for highest quality, productivity and robustness.

Component-specific Gas-Shield-Systems in 3D-metal-printing

A high-quality gas cover is very important for welding processes, not only in the process area but also in the hot temperature fields on the workpiece.
Through the use of additive manufacturing processes, complex gas protection systems can be manufactured individually for each component and in individual production at low cost.

Our patented gas protection systems extend the application possibilities and the potential of our modern welding torches as well as conventional processes in your production environment.
