Abstract: 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.

Abstract: A method to join a first enclosed workpiece and a second enclosed workpiece is provided. The first enclosed workpiece includes a first connecting end and a first cavity region. The second enclosed workpiece includes a second connecting end and a second cavity region. A backing member is placed in the first connecting end, with a first end within the first cavity region. A resilient member is positioned in the first cavity region, with a first portion within the first cavity region. The second enclosed workpiece is positioned proximal to the first enclosed workpiece to define a gap between the first connecting end and the second connecting end. Upon positioning, a second end of the backing member and a second portion of the resilient member are placed within the second cavity region. The first connecting end is then welded with the second connecting end over the backing member near the gap.

Abstract: An apparatus for supporting a backing member in an enclosed structure is disclosed. The enclosed structure includes a first plate defining an opening therethrough. The apparatus is configured to be disposed within the enclosed structure. The apparatus includes a clamp member and a support member configured to rotatably support the clamp member. The clamp member is rotatable about a rotation axis defined by the support member. The support member is further configured to abut a second plate spaced apart from the first plate. The clamp member is configured to be moved along the rotation axis relative to the support member and bias the backing member to contact with the first plate along the opening.
