Abstract
V rámci výzkumného projektu TH02020076 byla navržena a ověřena technologie výroby korozivzdorné austeniticko-feritické oceli A995 GR4A. Pro tuto jakost oceli v litém stavu byl vypracován postup svařování (WPQR – Welding procedure qualification record). Svařovací postup byl certifikován dle obvyklých standardů pro tloušťku stěny odlitku až 50 mm.
