摘要

The method of assembling the thin walled tubes of an exhaust line comprises expanding one of the ends (61) of the connection tube (60) to give it a spherical or conical shape. The formed end of the tube is positioned outside and in contact with the end connection of the exhaust line in a concentric manner. The positioned elements are then welded together.
