摘要
The method enables the butt welding of two metal pieces (1,2; 10,12) which are difficult to weld, particularly pieces of medium or high carbon content steel, with the use of a laser beam (L). Very briefly, it comprises the steps of: placing the surfaces of the pieces (1,2; 10,12) to be welded in mutual contact, directing two laser beams (L) at homologous points of two opposite sides (4,5) of the zone (S) of contact of the surfaces of the two pieces (1,2; 10,12), the beams (L) having a power such to ensure a thin, deep-penetration weld (6,7; M) having a substantially constant section and forming solidification menisci (6a, 7a) with convex profiles.
