An article is produced by welding a first piece to a second piece by a laser beam. The first piece, includes an open cavity and a first sealing surface. The second piece, has a second sealing surface, A chamber has controllable internal pressure. The first piece and the second piece are inside the closed chamber. The internal pressure of the chamber is changed to cause a flow of a gas from the open cavity. The open cavity is closed by moving at least one of the pieces The first sealing surface forms a partially gas tight preliminary joint with the second sealing surface The first piece and the second piece define an interface. The chamber is opened after the preliminary joint has been formed A welded seam is formed by focusing a laser beam to the interface after the chamber is opened. The first sealing surface and the second sealing surface are substantially planar.

Objects to be welded are joined together by laser welding to form adjacent nuggets. When a distance between central axes of the adjacent nuggets is p and a diameter of the adjacent nuggets in the objects to be welded is d, the adjacent nuggets are formed so as to satisfy an equation 1.0<p/d1.6.
