A weld kit is presented for use in creating a weld with limited access to a structure. The weld kit contains a back plate being a combination of a thermic material attached to a metallic material. Additionally, the weld kit has a lowering device secured to the back plate. A plurality of tacking nodes travel through both the thermic material and the metallic material of the back plate. The plurality of tacking nodes are operative to accept and distribute heat from a welding arc to create a tack weld at a location where at least one of the plurality of tacking nodes contacts a weld joint. The presented weld kit may be used to repair a damaged enclosed structure. Additionally, the presented weld kit may also be used to create an enclosed structure in a manufacture type environment.

Weld kit and method for limited access weld joints

A consumable insert for welding a first component to a second component is provided. The first component is positioned with respect to the second component in such a manner that a gap is defined between adjacent surfaces thereof. The consumable insert includes a body having a profile. The profile of the body matches a scan of a profile of the gap between the adjacent surfaces. The consumable insert also includes a dam portion having a profile. The profile of the dam portion matches, at least in part, a scan of corresponding surfaces of the first component and the second component respectively. The dam portion is provided in contact with at least one end of the body. The dam portion is configured to control an overflow of a weld puddle therefrom. The body and the dam portion are formed using three dimensional printing.
