Zusammenfassung:	The present invention provides a method of repairing welds in aluminium sandwich panels (1) comprising the steps of: making the root bead (2) of the weld (3) to be repaired by tungsten inert gas welding (TIG); and making up the remainder of the weld by metal inert gas welding (MIG). La présente invention concerne un procédé de réparation de soudures dans des panneaux sandwich en aluminium (1), comprenant les étapes suivantes: préparer le cordon de soudure (2) de la soudure (3) à réparer, par soudage par soudage à l'électrode de tungstène et réparer le reste de la soudure, par soudage MIG.
