A welding system includes a welder, a human-machine-interface, an identification-device, a test-device, a memory, and a controller-circuit. The welder creates an assembly between electrical-components. The human-machine-interface receives an input from an operator and displays instructions to the operator. The identification-device creates a label identifying the assembly. The test-device produces test-data of the weld-joint. The memory stores welder-process-data of the weld-joint. The controller-circuit activates the welder, stores the welder-process-data in the memory, determines whether the welder-process-data violates a quality-metric, determines a number of violating-weld-joints, activates an alert-device to alert the operator to violating-weld-joints, disables the welder when a number of violating-weld-joints exceeds a threshold, activates the identification-device to create the label, instructs the operator to attach the label to the assembly having the violating-weld-joints, instructs the operator to perform a test of the violating-weld-joints with the test-device, and stores the test-data of the violating-weld-joints in the memory linked to the identity.

A method for manufacturing a shaft body by welding a plurality of shaft members together and forming the shaft body, the method including: a primary tempering step of subjecting a range in at least one of the shaft members, which is in the vicinity of an end of another shaft member side adjacent thereto, to tempering before the shaft members are welded together so that a strength of an end side of a region thereof is lower than a strength at a side which is opposite to the end of the region thereof; a welding step of welding the shaft members together after the primary tempering step; and a secondary tempering step of tempering the vicinity of a weld part between the shaft members after the welding step.

Techniques and devices are disclosed for fabrication layout device. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces are positioned on the pattern so that they can be assembled to one another.

A method of attaching a first metal object to a second metal object is presented. The first metal object and the second metal object are dissimilar materials. The first metal object comprises an upper surface and a lower surface. The method comprises: positioning the first metal object in intimate contact with the second metal object such that the second metal object is in contact with the lower surface of the first metal object; identifying at least one attachment location on the upper surface of the first metal object where the first metal object is in intimate contact with the second metal object; adding a powdered metal on the upper surface of the first metal object at the at least one attachment location; and firing a heat source at the powdered metal to melt the powdered metal and drive the melted powdered metal through the first metal object and into the second metal object.

A braze bonded nail head includes a nail head lead having a first end with first and second sides and a braze alloy preform coupled to the first side of the first end of the nail head lead The braze bonded nail head further includes a weld joint centrally located on the braze alloy preform and extending through the braze alloy preform to the first end of the nail head lead. The weld joint is formed through micro-tig-welding, in alternative embodiments of the invention, one of the nail head lead and the braze alloy preform may include at least one protrusion extending therefrom, while the other of the nail head lead and the braze alloy preforms may include at least one interfit element configured to interfit with the at least one protrusion.

A method for connecting functional elements (14) to a shaft (10, having the following steps: (a) forming elevations (12) for receiving the functional elements (14), said elevations (12) being machined out of the shaft (10) by removing material, and (b) welding the functional elements (14) to the elevations (12) on the shaft (10).

A welding jig or gap tool and a method of operation is provided for welding management of the V-joint between facing pipe ends. One or more gap tools are distributed about the V-joint and actuated to maintain a welding gap along the V-joint during welding. The tool has a base portion removeably arranged between an alignment clamp and the pipe end. When actuated the gap tool bears against the alignment clamp and a cone is driven into the V-joint to establish and to maintain the gap between pipe ends.

A stress-relief heat treatment method for stress-relief heat-treating a rail which is welded includes arranging at least one pair of an induction heating coil to face the rail at both sides of a welding center along the longitudinal direction of the rail while being separated from the welding center of the rail by 20 mm to 300 mm in a longitudinal direction of the rail and being an axial direction of the induction heating coil parallel to the longitudinal direction of the rail. The method further includes flowing a current to the induction heating coil arranged at one side of the welding center and to the induction heating coil arranged at the other side of the welding center being opposite to each other, and induction heating the rail to a heating temperature of 400 C. or higher and 750 C. or lower.

In the present invention, a flat emitter is formed from emitter material preforms shaped as thin sheets of the emitter material. These sheets are subjected to various levels and/or amounts of mechanical working during their initial formation and are bonded to one another to create a preform having the desired thickness. The preform including the bonded sheets is subsequently worked to shape the preform into the desired configuration for the emitter. The working of the sheets of emitter material utilized to create the preform and the working of the preform to form the emitter provide a highly creep-resistant emitter that significantly improves the operation and useful life of the resulting emitter.

A method for securing a wear resistant body to a steel base comprise locating a body of tungsten carbide on a surface of the steel base, surrounding the body of tungsten carbide with a weld pool and while the weld pool is hot, slowly cooling the weld pool so as to assist with adhesion of the weld pool to the body of tungsten carbide by the application of head from frictional contact with a rotary wire brush.
