PROBLEM TO BE SOLVED: To achieve down-sizing of a seam-welding device equipped with a mechanism for tacking and seam-welding.SOLUTION: A seam-welding device includes: a turn table 5 rotatable in a horizontal plane; plural retention mechanisms 50 which are located on a surface of the turn table 5; a package transportation device 6 which performs transportation and shipping of a package 10 for a retention mechanism 50 positioned at a first position among the retention mechanisms 50 which move on a rotation route in association with rotation of the turn table 5; a weldment head 7 for tacking and permanent welding which transports a lid 11 onto the package 10 held by a retention mechanism 50 positioned at a second position on a rotation route, and performs tacking and seam-welding in a first direction between the lid 11 and the package 10; and a weldment head 8 for permanent welding which performs seam-welding between the package 10 held by a retention mechanism 50 positioned at a third position on a rotation route and the lid 11 in a second direction orthogonal to the first direction.SELECTED DRAWING: Figure 1 |
