Laser Beam Welding of Borated Stainless Steel

摘要

Laser beam welding of the absorption tubes made from stainless steel with increased boron content represent suitable production method of storage for spent nuclear fuel. This contribution presents results of weld joints investigation. The experiments were performed on borated stainless steel AISI 304 B6B with boron content 1.74% wt. Weld joints were prepared by laser beam welding using fiber laser generator and examined by optical and electron microscopy.
