Abstract
Obtention de courbures complexes dans de grandes plaques métalliques. On trace sur la plaque un motif de lignes de chauffage dérivé de la projection sur la plaque de la surface courbe à obtenir. On chauffe fortement suivant ces lignes, puis on refroidit rapidement, par exemple au moyen d'un chalumeau suivi d'une pomme d'arrosage. Le refroidissement produit un retrait notable, perpendiculairement à la ligne de chauffage. On chauffe dans un ordre préfixé en passant par tous les quadrants de la plaque, de façon que celle-ci subisse une transformation d'ensemble graduelle. Application au façonnage d'éléments de coques de navires, citernes, réacteurs chimiques, etc.
