Abstract:The thick plate TB19 was jointed by large high-voltage electron beam welding, achieving a 130 mm depth without defects. The organizational structure of the joints was analyzed; the mechanical properties, micro hardness testing and the fracture toughness test were done. The plastic nature can match the toughness. The TB19 joints welded by EBW will be of highly efficient and high quality.
Key words: TB19 titanium alloy; heavy plate; electron beam welding (EBW)
