A piece insertion method for a pipe;

• comprising the steps of:
• providing a pipe and providing at least one piece to be inserted into said pipe;
• ejecting said piece from an ejection unit,
• advancing said piece inside said by a piece advancing unit, placing said piece on a lifting device which moves according to an up and down lifting motion and wherein said lifting device is actuated by at least one of the group consisting of an electro-mechanical actuator, an electromagnetic actuator, a magnetostrictive actuator, and an electrical actuator,
• catapulting said piece inside the pipe towards an upper inner surface of said pipe using said up lifting motion of said lifting device, such that said piece enters for the first time in contact with said upper inner surface of said pipe, in order to weld said piece against said inner surface, with said piece being parallel or substantially parallel to said inner surface of said pipe on impact with said inner surface.
