摘要： A method of brazing two metal components (8, 9) comprises the following operating steps : prearranging a first metal component (8) provided with a connection end (8') and a second metal component (9) provided with a connection portion (9'), with at least the first component (8) of tubular shape, arranging the first component (8) of tubular shape with its connection end (8') facing the connection portion (9') of the second component (9), defining with the latter a junction slit (21), prearranging a bead (11) of filler material on the mouth of the junction slit (21), irradiating at least one fraction of the connection end (8') of the first component (8) and/or at least one fraction of the connection portion (9') of the second component (9) with at least one laser beam (12), defining thereon an impact area (13) that is outside with respect to the bead (11), in a manner such that the laser beam (12) does not directly hit the bead (11) itself, transmitting, via conduction, thermal energy from the impact area (13) to the bead (11), and melting the filler material, in which the thermal energy, transmitted via conduction to the bead (11), at least partially melts the filler material which consequently penetrates via capillarity into the junction slit (21).
