The method disclosed is for thermoplastic welding, by fusion bonding, an integral assembly of at least two composite thermoplastic parts (2, 4). One part (2) is integrally molded with a plurality of ribs (7) to be used and bonded to their mates (8) of the counterpart (4). A heat generator assembly (3) applies heat energy to the ribs (7, 8) of the parts so as to heat and thus fuse them. Immediately after the application of the heat energy, pressure is applied to the heated parts (2, 4) to push them together. The heated ribs (7) of the part (2) are consequently aligned and bonding contacted with the heated ribs (8) of the counterpart (4). This application of pressure is maintained during a predetermined period to facilitate fusion bonding of the ribs (7, 8). Finally, an integral assembly in which the part (2) is rigidly welded to the counterpart (4) the ribs (7, 8) is produced.
