<p><P>PROBLEM TO BE SOLVED: To eliminate non-uniformity in welding one member and other member by making the horizontal position of the other member to the one member accurate. <P>SOLUTION: A can sealer comprises a retaining section 20 which retains the one member 61, a plurality of positioning sections 10 which position the other member 62 in the horizontal direction, a welding section 30 which welds both members with energy added, a lifting section 50 which pushes both members upward, a vertically positioning section 40 which touches both members, and a retracting section which positions the positioning sections 10 to retraction points. The one member 61 and the other member 62 are pushed up by the lifting section 50. The retracting section positions the positioning sections 10 to the retraction points, after the other member 62 is abutted against the vertically positioning section 40, thereby the vertical interval between the peripheral part of the other member 62 and the peripheral part of the one member 61 is lessened, and before part at least of the one member 61 and the other member 62 positioned on the inner circumferential side of the positioning sections 10 is welded with energy from the welding section 30. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
