Heating radiator production method - presses flat tubes inwards at curved edges for pressure-welding to manifolds

The method produces a heating radiator with flat parallel tubes spaced apart and connected at the ends to feed and return manifolds. These are pressure-welded together at connecting openings. Each flat tube(3) is pressed inwards at its curved edge(5) for connection to the manifold(1) so as to form a recess(6), widening it(7) in the transverse direction in the process, and forming a curved portion with a greater radius(r). The manifold is pressed against this portion, without contact with the sloping flanks(9) of the recess, at the start of the welding operation. ADVANTAGE - Lower cost, there being no formation of splash metal to clean off.
