METHODS FOR REDUCING RESIDUAL STRESS IN ELONGATE WELDMENTS

Methods of manufacture include welding two or more elongate members together to define an elongate weldment, wherein the welding results in a weld region that is in tension and regions adjacent to the weld region that are in compression, and longitudinally stretching the elongate weldment. Tools and...

Zusammenfassung:	Methods of manufacture include welding two or more elongate members together to define an elongate weldment, wherein the welding results in a weld region that is in tension and regions adjacent to the weld region that are in compression, and longitudinally stretching the elongate weldment. Tools and systems for manufacturing elongate weldments, as well as apparatuses, such as aircraft, that include elongate weldments, also are disclosed. L'invention concerne des procédés de fabrication comprenant le soudage de deux éléments allongés ou plus ensemble en vue de définir un élément soudé allongé, le soudage donnant lieu à une région soudée qui est sous tension et à des régions adjacentes à la région soudée qui sont en compression, et l'étirement longitudinal de l'élément soudé allongé. Des outils et des systèmes pour la fabrication d'éléments soudés allongés ainsi que des appareils, tels qu'un avion, qui comprennent des éléments soudés allongés, sont également décrits.
