摘要 |
Dents are machined away by introduction of a rotating drilling tool through the tube base into the interior of a tube section. A part tube section is separated by a rotating cutting tool in the interior of the tube section. The connecting weld between the tube and the tube base is removed by mechanical machining. After cleaning of the bore (3), a new part tube (6) is introduced through the bore of the tube base (1). The joining of the new part tube with the heat exchange tube (4) remaining in the heat exchanger is achieved by an inner tube and orbital welding by an inner tube welding apparatus (14) fixed on a retainer (8) and a drive (9) inserted through the new part tube. |
