ABSTRACT:
On the welding arm of a welding machine is mounted a coaxial application pipe with removable transport means and an application nozzle. Into this application pipe is fed a block-shaped hot-melt mass, in the direction opposite the advance direction of the sheet metal tube, guided in direction (V) of the application tube, melted in the area of a narrowing heater, passed through a supply tube to the application nozzle and applied or sprayed as a hot-melt strip to the inside of the longitudinal weld seam of sheet metal tubes.
The application of a hot-melt strip is suitable in particular for the protection of the longitudinal seam of a tin-plated can shell.
