摘要： A method for making elbow connections between at least a first tubular element (2) and at least a second tubular element (2'), comprises making in at least an end of said first tubular element (2) and in at least an end of said second tubular element (2') a respective edge (16; 16') that is tilted with respect to said at least an end.
An apparatus for making elbow connections between tubular elements (2) comprises a device (1) for making, at at least an end (2a) of a tubular element (2), an edge (16) that is tilted with respect to said at least an end.
An apparatus for making elbow connections between tubular elements (2) comprises a further device (100) that is suitable for welding together respective ends (2a) of two tubular elements (2; 2') at respective edges (16, 16') that are tilted with respect to said respective ends (16; 16').
