Abstract

L'invention concerne un procédé et une installation de recuit ou de revenu d'au moins un point de soudure et/ou d'au moins un cordon de soudure sur un ensemble (9) formé par au moins deux pièces soudées entre elles, le procédé comprenant - une étape de chauffage jusqu'à une température donnée de recuit ou de revenu d'une zone de l'ensemble formé par au moins deux pièces soudées entre elles avec maintien à ladite température donnée de recuit ou de revenu pendant un temps prédéterminé, la zone chauffée comprenant au moins un point de soudure et/ou au moins cordon de soudure ; et - une étape de refroidissement de ladite zone chauffée ; le procédé et l'installation étant remarquables en ce que l'étape de chauffage est une étape de chauffage par induction mise en œuvre par un dispositif de chauffage par induction électromagnétique (5).The invention relates to a method and an installation for annealing or tempering at least one weld point and / or at least one weld bead on an assembly (9) formed by at least two parts welded together, the method comprising - a step of heating up to a given annealing or tempering temperature of a zone of the assembly formed by at least two parts welded together with maintenance at said given annealing or tempering temperature for a predetermined time , the heated zone comprising at least one weld point and / or at least weld bead; and - a step of cooling said heated zone; the method and the installation being remarkable in that the heating step is an induction heating step implemented by an electromagnetic induction heating device (5).
