Abstract:
1. An arrangement comprising: a first metal sheet having an L-, U- or V-shaped flange which is folded over, a second metal sheet which overlaps said flange on the inside or the outside or faces an end or a face side of said flange to form a joint with said flange, a flanging and welding or soldering tool with wherein the flanging member folds the flange of the first metal sheet into a position or orientation required for welding or soldering, and the welding or soldering tool produces a seam near to the position where the flanging member is in contact with the flange, and wherein the flanging member during folding the flange in said position presses on the first metal sheet and/or on the second metal sheet for the flanging process, and at the same time said flanging member presses the first and second metal sheet against each other for the welding or soldering process so that the second metal sheet for the welding or soldering process abuts the inside, the outside or the face side of a free end of the flange and the welding or soldering tool connects the second metal sheet directly to said inside or said outside or said face side of said free end of the flange of the first metal sheet.
