Abstract
E' descritto un metodo per realizzare la saldatura di un tubo (5) alla parete (4) di una corrispondente sede (3) di alloggiamento ricavata in un pannello (2) per un elemento (1) scambiatore di calore. Più in particolare, tale metodo si propone di ottenere una saldatura che eviti la formazione di zone interstiziali vuote tra un tubo (5) e parete (4) le quali possono provocare conseguenze dannose e pericolose per l'elemento (1) e gli impianti nei quali questo viene impiegato. Questo scopo è ottenuto grazie ad un metodo che prevede, tra le altre, una fase combinata di riscaldamento e pressurizzazione interna del tubo (5) secondo valori tali da raggiungere la condizione di scorrimento viscoso del materiale metallico di cui è composto; la deformazione che consegue a questa fase permette di far aderire il tubo (5) alla parete (4) in maniera perfetta e completamente controllabile e raggiungere quindi lo scopo desiderato.Peraltro la deformazione controllata del tubo permette di sollecitare il pannello (2) che ospita la sede (3), entro i limiti di volta in volta richiesti per preservarne la sua integrità strutturale; questo aspetto vantaggioso dell'invenzione la rende quindi particolarmente adatta nel caso di pannelli (2) in grafite, ceramica o altri materiali fragili.
