Ce procédé de soudage destiné à souder une pièce qui, par exemple, comporte un premier élément et un second élément chevauchant le premier élément dans une première direction et comprenant un matériau différent du premier élément, ledit soudage étant mis en œuvre par l'irradiation d'une surface avec une lumière laser, ladite surface étant située sur une partie d'extrémité dans la direction opposée à la première direction, et soudant ainsi le premier élément et le second élément, une partie soudée qui comporte un métal soudé s'étendant à partir de la surface et à travers le premier élément dans la première direction vers le second élément est formée dans la pièce, et lorsque l'épaisseur du premier élément dans la première direction est définie comme étant T1, la profondeur de pénétration Wd du métal soudé dans la première direction est T1 < Wd ≤ T1 + 0,5 (mm). De plus, le rapport Ew2 = Ww2/Wd2 de la largeur Ww2 dans une seconde direction croisant la première direction par rapport à une profondeur de pénétration Wd2 d'une seconde région dans la première direction peut être égal ou supérieur à 1.
