Abstract:
A method of constructing a metal tubular frame structure utilizing a first tubular member 30 and a second tubular member 32 is provided. The method involves utilizing at least one opening 34, 44, 46 in the first tubular member and at least one end tab 48, 50 on the second tubular member that together produce a keyed tubular joint when the second tubular member engages the first tubular member with the tab inserted within the opening. Keyed tubular insert-type joints, keyed tubular miter-type joints and keyed tubular flush-type joints can be formed.
Abstract:
A welded blank assembly (200) includes a capping material (210) in a weld region (220) of the assembly. The capping material can help protect a weld joint (208) joining first and second sheet metal pieces (12, 112) together. At least one of the sheet metal pieces has a coating material layer (18) that is removed prior to forming the weld joint so that the coating material does not contaminate the weld joint. The removed coating material can be collected before the weld joint is formed and reapplied as part of the capping material after the weld joint is formed, effectively changing the coating material from a potential weld contaminant to a weld joint protectant. The capping material may also include additional material from a source other than the coating material layer.
Abstract:
In a first embodiment, at a time of magnetic pulse welding, a stepped tube profile machining process axially bores a walled tube (10) from an end inward to a transition depth (14) to form a section with a reduced wall thickness (16) and then axially bores the walled tube (10) from the transition depth (14) to a fall off depth (18), thereby forming a section with a maximized welding wall section (20). In a second embodiment, also at a time of magnetic pulse welding, a surface angle tube profile machining process axially bores at a surface angle a walled tube (30) from an end to a bore length (34) to form an angular welding wall thickness (36) inward to a maximized wall section (38). For both embodiments, the bored surfaces are virgin with no pits, oil, residue, or oxidation thereon, thus making the machined walled tubes available for immediate magnetic pulse welding.
Abstract:
A method and system (100) is provided for welding, using a laser-hot-wire welding system, in an out-of-position state, where the weld joint (200) has a narrow groove opening but the groove of the weld joint (200) has a wider portion than that between the workpiece (205, 210) surfaces than at the groove opening through which the welding operation is directed.

Abstract:
The invention relates to a method for making T-branch joints for pipes. The method comprises making a hole (3) in a pipe (1) to be branched and attaching a branch pipe (2) by welding to the edges of the hole. Welding is conducted from inside the pipes. The hole (3) is made smaller than the internal diameter of the branch pipe (2) with edges (4) of the hole (3) providing a step which extends inside the internal diameter of the branch pipe. The material of the step (4) is melted by internal welding to form part of a weld joint (5).

Abstract:
Method of producing a heat exchanger comprising a number of thin plates (8) of aluminum by processing at least a portion of the edges (16), at least the ends, into a thickness allowing, and joining the edges (16) of said plates (8) to provide channels between each pair of said plates, whereafter manifolds for delivering liquid to and from the channels are secured to the processed portions of the edges (16) by welding. As a result there is obtained a heat exchanger, which is more flexible and cheaper in production than previously known.
