Mechanism for soldering seams, especially the side seams of moving 'tin' can bodies, comprises means for guiding each seam along a path, an applicator rotatable counter to the direction of can seam travel and having one portion immersed in molten solder and another solder wettable portion not so immersed, the other portion including a solder applying rim in substantially tangential relation to a locality of the seam joint in the path, and means for maintaining an atmosphere of inert gas about the non-immersed applicator portion and the mentioned locality to avoid oxidation of the solder as applied at the joint and also while carried thereto by the applicator.
