Abstract
A pore-free weld connection and a method for manufacturing such a weld connection between first, second and third components (1, 3, 5, 13, 15, 17), which are connected together by means of a closed weld seam (7, 18), and of which one component (5, 17) has, at a start- and end-point (9, 11, 21, 23) of the weld seam (7, 18), a cavity (6, 19) serving for a root-side degassing of a weld puddle.
