    • Various embodiments of the invention include solutions for chamber- less thermal joining. A first aspect includes a system for performing a thermal joining of a joint space defined by a metallic part without an environmental chamber thereabout. The system may include an induction coil (110) for heating an area adjacent to the joint space defined by the metallic part (102A, 102B) for the thermal joining of the joint space. The system may also include a gas lens (120) for directing a shielding gas towards the joint space, and a valve system (132) for controlling a flow of the shielding gas from the gas lens (120). A vacuum system (122) creates a negative pressure in the metallic part (102A, 102B) to urge the shielding gas through the joint space during the thermal joining, thus allowing thermal joining of the metallic part without an environmental chamber thereabout.
    • 本发明的各种实施例包括无室温热连接的解决方案。 第一方面包括一种用于执行由金属部件限定的接合空间的热接合而不在其周围的环境室的系统。 该系统可以包括用于加热由金属部分(102A,102B)限定的关节空间相邻的区域以用于接合空间的热连接的感应线圈(110)。 该系统还可以包括用于将保护气体引向关节空间的气体透镜(120)和用于控制来自气体透镜(120)的保护气体流动的阀门系统(132)。 真空系统(122)在金属部件(102A,102B)中产生负压力,以在热连接期间促使保护气体通过接合空间,从而允许金属部件在其周围没有环境室的热接合。
