  • Welding fixture
    Patent number: 10591338
    Abstract: A welding fixture for releasably engaging a weldable object includes a support body having a fluid passage, and a receiver coupled to the support body having an internal chamber that receives the object. At least one fluid delivery tube is disposed along the receiver and is in fluid communication with the fluid passage of the support body. The fixture allows the weldable object to be precisely positioned for welding, and supplies a fluid delivery system for delivering inert gas to the weld site.
