To improve the welding quality of a weld between a catheter balloon (1) and a catheter shaft (2) of a balloon catheter (3) it is suggested according to the invention to arrange a welding energy absorbing device (5, 5'), preferably in the form of a coloured tubing, in the area of a fixation site (V) after attaching a pre-fixation (4) and then to irradiate this welding energy absorbing device (5, 5') with the radiation energy (L) to carry out the welding. After the welding the pre-fixation (4) and the welding energy absorbing device (5, 5') are removed.
