In a valve structure wherein a cylindrical hub extends through a circular opening in the valve body into the interior, the metal around the opening is swaged outward to form a generally cylindrical weld joint portion and the hub has a skirt around it with an annular edge which is disposed adjacent to and aligned with the annular end of the swaged joint portion. A full penetration butt weld between the two annular edges secures the hub in place.
