The device (100) for welding thermoplastic parts comprises: a matrix (10) for positioning the parts to be assembled, the matrix (10) including an amagnetic insulating insert (12) that defines joining zones (25) in which the welds must be produced; a bladder (11) defining a sealed volume and means for producing a partial vacuum in the sealed volume; and means for moving a magnetic induction head (30) to near the joining zones (25) and without making contact with the bladder (11). The welding process comprises the successive steps of positioning at least one first part (21), then of placing metal inserts (23) on those areas of the first part (21) corresponding to the joining zones (25) that must be welded, and then positioning at least one second part (22). Next, a bladder (11) is put in place covering the parts and a partial vacuum is created in the volume defined by the bladder. The magnetic induction head (30) is moved to produce the weld bead without contact while the partial vacuum is maintained. |
