METHOD FOR FORMING A WELDED CONNECTION BETWEEN A TUBESHEET AND A NUMBER OF TUBES AND A DEVICE PRODUCED BY SUCH METHOD

摘要

The invention relates to a method for forming a connection between a tube sheet and at least one tube and a device manufactured according to such a method comprising: - providing a tube sheet (2) with a first surface (10) and a second surface (11) and a number of bores (12) extending from the first surface (10) to the second surface (11), - providing the cube (1) of a pliable material with an exterior shape and dimensions, which enable the tube (1) to be a accommodated in a corresponding bore (12), - placing the tube (1) in the corresponding bore (12), such that an end portion of the tube (1) protrudes from the side of the first surface (10) of the tube sheet, (2), - flaring the protruding end portion of the tube (1), to form a flare (20), - making a welded connection between the tube sheet and the tube at the circumference (21) of the flare (20).
