Abstract
L'invention concerne une pièce en acier soudé (1) obtenue par soudage d'une première feuille (2) avec une seconde feuille (3), la première et/ou la seconde feuille (2, 3) étant constituées d'un substrat en acier et comprenant un revêtement en alliage d'aluminium, ledit soudage utilisant un fil de soudage qui, après fusion et refroidissement, constitue un cordon de soudure (4) reliant la première feuille (2) à la seconde feuille (3) et faisant partie de ladite partie en acier soudé. Selon l'invention, la première et/ou la seconde feuille (2, 3) constituent une partie formée pressée à chaud, et le bord périphérique respectif (2a, 3a) des première et seconde feuilles (2, 3) se trouve dans une configuration de type bord à joint dans laquelle le bord périphérique (2a) de la première feuille (2) est disposé au-dessus, et sur ou à proximité de la face supérieure (3all) d'une partie d'extrémité (3al) du bord périphérique (3a) de la seconde feuille (3) qui est étendue par une partie de jonction inclinée (3a2), au moins une partie de la face supérieure (3a21) de la partie de jonction inclinée (3a2) délimitant au moins latéralement avec le bord (2a3) du bord périphérique (2a) de la première feuille (2) une rainure (5) recevant le cordon de soudure (4), la partie d'assemblage inclinée (3a2) s'étendant par une partie de soudage (3a3) en continuité longitudinale avec le bord périphérique (2a) de la première feuille (2).
