Title: METHOD FOR JOINING VERY THICK TUBULAR PARTS BY MAGNETIC PULSES; CORRESPONDING ARTICLE
Abstract:
The invention relates to a method for joining two tubular parts (2, 3), an internal part (3) and an external part (2), by magnetic pulses, said external part (2) having an annular wall (20) having an outer surface (22). The method comprises the steps: of reducing, over a longitudinal portion (23) of the external part (2), a thickness of the annular wall (20) of the external part (2) such that the annular wall (20) has a decreasing thickness over said longitudinal portion, of positioning the tubular parts (2, 3) one inside the other, forming an overlap region (25) covering the longitudinal portion (23), of positioning the tubular parts (2, 3) next to a coil (10) such that the longitudinal portion (23) is disposed opposite an active part of said coil (10), and of connecting the two tubular parts (2, 3) by magnetic pulses.
