WELDMENT WITH ISOLATION POCKET FOR REDUCTION OF WELD-INDUCED DISTORTION

A weldment in which a first component defines a bore, a second component is received in the bore and a weld is employed to couple the second component to the first component. The first component has an isolation pocket formed about the bore such that an annular projection having an annular collar po...

Beschreibung
Zusammenfassung:	A weldment in which a first component defines a bore, a second component is received in the bore and a weld is employed to couple the second component to the first component. The first component has an isolation pocket formed about the bore such that an annular projection having an annular collar portion is formed. The isolation pocket is sized and positioned relative to the weld such that the annular collar portion is deflected about the base into a position that is radially inwardly from a position of the annular collar portion prior to the formation of the weld such that the isolation pocket controls axial shrinkage associated with the formation and cooling of the weld. L'invention concerne un ensemble soudé dans lequel un premier composant définit un alésage, un second composant est reçu dans l'alésage et une soudure est utilisée pour coupler le second composant au premier composant. Le premier composant comporte une poche d'isolation formée autour de l'alésage de sorte qu'une saillie annulaire possédant une partie collier annulaire soit formée. La poche d'isolation est dimensionnée et positionnée par rapport à la soudure de sorte que la partie collier annulaire dévie autour de la base jusqu'à une position située radialement vers l'intérieur par rapport à une position de la partie collier annulaire avant la formation de la soudure, la poche d'isolation régulant ainsi le rétrécissement axial associé à la formation et au refroidissement de la soudure.
