Abstract
A method for connecting at least one basin of metal sheet to a basin opening of a frame formed of metal sheet by positioning a metal basin with its rim surrounding a basin opening of the frame so that the edge of the opening projects inwardly beyond the rim of the basin and melting this projecting rim by welding without employing additional work material. According to a preferred embodiment, this method is performed by apparatus having a presser plate displaceably mounted on a machine frame, a plunger on a lower end of the frame for centering the basin and basin opening, presser ring attached to the upper end of the cross-head that forms a gap with respect to an upper edge of a basin holder of the presser plate and the plunger necessary for effectuating welding of the basin to the frame, and at least one welding torch mounted so as to be displaceable along a guide track with its nozzle directed at a constant setting angle toward the gap between the plunger and the presser ring.
