The invention discloses a method for welding tubular elements (10) that utilizes a method for defining the outline of sections of tubular elements which comprises the steps of: arranging a scanning device (1) and defining a respective scanning resolution (RS); arranging a tubular element (10) that has outlines (11); defining a framing position (PI) for scanning an outline (11) on the scanning device (1); scanning the outline (11) so as to obtain an image (20) of the outline (11); defining edges (21) of the section in the image (20); deforming the edges (21) as a function of the outline (11) so as to define a refined image (20p); scale mapping (M) the outline (11) starting from the refined image (20p) as a function of the resolution (RS); arranging at least two tubular elements (10) comprising respective zones to be welded (4) facing each other; heating the zones to be welded (4); coupling the zones to be welded (4), one to the other; making a groove (19) in each zone to be welded, of the tubular elements (10), prior to the heating step, the groove (19) being made by means of a removal procedure on the perimeter of the outline (11) of each tubular element (10), in which removal is carried out as a function of the scale mapping (M). The invention also discloses an apparatus for welding tubular elements (10) for implementing the method disclosed. |
