Abstract

L'invenzione riguarda un procedimento per produrre elementi costruttivi dotati di cavità, in cui un pacco di lamiere liscio o sagomato formato da almeno una lamiera superiore, da una lamiera inferiore, da una commettitura di separazione e da uno strato parziale di agente di separazione, nella commettitura di separazione viene saldato per diffusione in corrispondenza di zone della commettitura di separazione prive di agente di separazione. A tale scopo la lamiera superiore e la lamiera inferiore in corrispondenza dei loro bordi esterni, vengono unite a tenuta di gas in modo da formare un pacco di lamiere e un sistema di adduzione del gas verso la commettitura di separazione viene incorporato concomitantemente fra le lamiere del pacco di lamiere e durante la saldatura dei bordi esterni.
