A mating tube may then slide over the metal fabrication locator device such that the perimeter of the metal fabricator locator device biases the inside sidewall of the mating tube to precisely align it on the receiving tube. This eliminates the use of additional weld fixtures for positioning of tube members in a metal fabrication assembly. This also allows an end user to construct and weld a product together on their own with precise assembly. Also disclosed herein are methods of manufacture and assembly of a metal fabrication assembly using a metal fabrication locator device. ## Claims ### Claim 1 A metal fabrication assembly, the metal fabrication assembly comprising: a locator device; a mating tube; and a receiving tube; the locator device comprising a plate comprising a front surface, a back surface, and an exterior perimeter corresponding to an interior void of the mating tube, the plate fully inserted into the interior void of the mating tube and biasing an interior sidewall of the mating tube; the plate further comprising one or more fasteners inserted into one or more fastening apertures extending through the front surface and the back surface of the plate, the one or more fasteners mechanically securing the back surface of the plate to an exterior sidewall of the receiving tube; wherein a first end of the mating tube mates directly with the exterior sidewall of the receiving tube fully concealing the plate within the mating tube; and wherein the exterior sidewall of the receiving tube is an outer perimeter of the receiving tube. ### Claim 2 (depends on 1) The assembly of claim 1 wherein the locator device positions the mating tube of the metal fabrication assembly relative to the receiving tube of the metal fabrication assembly and the mating tube and the receiving tube are welded together with a weld directly between the mating tube and the receiving tube. ### Claim 3 (depends on 1) The assembly of claim 1 wherein the locator device is not a weld fixture. ### Claim 4 (depends on 1) The assembly of claim 1 wherein the exterior perimeter of the plate is less than or equal to an interior perimeter of the interior void of the mating tube of the metal fabrication assembly. ### Claim 5 (depends on 1) The assembly of claim 1 wherein the plate further comprises one or more light weighting apertures or light weighting recesses. ### Claim 6 (depends on 1) The assembly of claim 1 wherein multiple sections of the exterior perimeter of the plate are raised from the exterior sidewall of the receiving tube of the metal fabrication assembly when fastened to the receiving tube forming a void between the plate and the receiving tube. ### Claim 7 (depends on 1) The assembly of claim 1 wherein the plate is a flat plate. ### Claim 8 (depends on 1) The assembly of claim 1 wherein the plate is a partial tube with the front surface being concave and the back surface being convex. ### Claim 9 (depends on 1) The assembly of claim 1 wherein the plate is a partial tube inverted on the exterior sidewall of the receiving tube of the metal fabrication assembly. ### Claim 10 (depends on 1) The assembly of claim 1 wherein the plate is a bent angle having a leg extending from the front surface. ### Claim 11 (depends on 10) The assembly of claim 10 wherein the leg comprises a positioning aperture. ### Claim 12 (depends on 11) The assembly of claim 11 wherein a fastener is inserted through the positioning aperture of the leg for securing the plate to a positioning aperture of the mating tube of the metal fabrication assembly. ### Claim 13 (depends on 1) The assembly of claim 1 wherein the exterior perimeter of the plate comprises one or more interferences. ### Claim 14 (depends on 13) The assembly of claim 13 wherein the exterior perimeter of the plate is incrementally larger than an interior perimeter of the interior void of the mating tube providing an interference of the one or more interferences between the plate and the mating tube and holding the mating tube to the plate. ### Claim 15 (depends on 1) The assembly of claim 1 wherein the receiving tube of the metal fabrication assembly is round and the back surface of the plate is attached to the round receiving tube at a tangent of the round receiving tube and the one or more fasteners extend through the tangent. ### Claim 16 A metal fabrication assembly comprising: a first locator device; a mating tube; and a first receiving tube; the first locator device comprising a front surface, a back surface, an exterior perimeter corresponding to an interior void of the mating tube; one or more fasteners inserted into one or more fastening apertures extending through the front surface and the back surface of the first locator device securing the back surface of the first locator device to an exterior sidewall of the first receiving tube; wherein the first locator device is fully inserted into the mating tube and the exterior perimeter of the first locator device biases an interior sidewall of the interior void of the mating tube; wherein a first end of the mating tube mates directly with the exterior sidewall of the first receiving tube fully concealing the first locator device within the mating tube; and wherein the exterior sidewall of the first receiving tube is an outer perimeter of the first receiving tube. ### Claim 17 (depends on 16) The metal fabrication assembly of claim 16 wherein the receiving tube is secured to the mating tube by a weld about an exterior perimeter of the mating tube and the exterior sidewall of the first receiving tube. ### Claim 18 (depends on 17) The metal fabrication assembly of claim 17 wherein the first locator device is separated from the weld by the mating tube. ### Claim 19 (depends on 16) The metal fabrication assembly of claim 16 further comprising a second locator device comprising a front surface, a back surface, an exterior perimeter corresponding to an interior perimeter of the mating tube; one or more fasteners inserted into one or more fastening apertures extending through the front surface and the back surface of the second locator device securing the back surface of the second locator device to an exterior sidewall of a second receiving tube; wherein the second locator device is fully inserted into the mating tube and the exterior perimeter of the first locator device biases an interior sidewall of the interior perimeter of the mating tube; and wherein the second end of the mating tube is opposite the first end of the mating tube and mates directly with the exterior sidewall of the second receiving tube fully concealing the first locator device within the mating tube. ### Claim 20 A metal fabrication assembly comprising: a locator device; a mating tube; and a receiving tube; the locator device comprising a front surface, a back surface, an exterior perimeter corresponding to an interior void of the mating tube; one or more fasteners inserted into one or more fastening apertures extending through the front surface and the back surface of the locator device securing the back surface of the locator device to an exterior sidewall of the receiving tube; wherein the locator device is fully inserted into the mating tube and the exterior perimeter of the locator device biases an interior sidewall of the interior void of the mating tube; wherein a first end of the mating tube mates directly with the exterior sidewall of the receiving tube fully concealing the locator device within the mating tube, the receiving tube is secured to the mating tube by a weld directly between an exterior perimeter of the mating tube and the exterior sidewall of the first receiving tube, and the locator device is separated from the weld by the mating tube; and wherein the exterior sidewall of the first receiving tube is an outer perimeter of the first receiving tube.
