This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:Substance of scientific project is solution of problems with weldability of duplex steels with laser and electron beam. Welding of duplex steels with arc processes has been solved and is currently used in practice. The welding of it's with laser and electron beam, generally shows problem with attaining of suitable proportion of structural components austenite/ferrite around 50/50% and owing to poor corrosion resistance. Balance of phases ferrite -- austenite is important primarily from corrosion aspect, which is the mainly of priority of duplex steels before other stainless steel.
