A fastener welding apparatus having a frame assembly, a welding assembly, a coupling assembly and a locating assembly. The welding assembly has a welder frame and a welding electrode assembly coupled thereto. The coupling assembly has a suspension frame, a frame axle and a welding axle. The frame axle is fixedly engaged to the frame assembly and the welding axle is fixedly engaged to the welding assembly. The suspension frame is pivotably coupled to each of the frame axle and the welding axle. The locating assembly is structurally configured to selectively allow the suspension frame to pivot relative to the frame axle and the welding axle.

A method of forming a screen assembly includes arranging a first end portion of each of a plurality of rib members into a rib alignment jig, positioning a sleeve about the rib alignment jig with an inner surface of the sleeve abutting the first end portion of each of the plurality of rib members, and resistance welding the sleeve to the first end portion of each of the plurality of rib members.

Welding apparatus, for example for a workpiece, comprises resistance welding electrode wheels which form a weld seam between components of the workpiece. The formed weld is monitored by an ultrasonic probe which is situated behind the rollers with reference to the weld direction. The ultrasonic probe comprises a linear phased array of piezoelectric elements. The probe enables real-time monitoring of the welding process, with the facility to adjust the process to correct deviations.

A welding apparatus for resistance-welding a tubular member and a bar member includes: a positioning jig configured to make contact with the bar member from one side of the bar member in a direction perpendicular to an extending direction of the bar member; a first power supply jig configured to press the bar member from the other side of the bar member in the direction; a second power supply jig provided on an anti-bar member side of the tubular member and configured to apply pressure to contact surfaces of the bar member and the tubular member; and means for supplying, with the bar member pressed between the positioning jig and the first power supply jig and the second power supply jig applying pressure to the contact surfaces, electric current to the first power supply jig, the bar member, the contact surfaces, the tubular member and the second power supply jig.

A welded steel door including a pan having a bottom surface forming a first face of the door and flanges extending on opposite edges thereof forming opposite side edges of the door, the flanges having a lid engaging surface spaced from the bottom surface, a lid having a top surface forming a second face of the door opposite the first face, opposite edges of the top surface each having a hem mated with a respective lid engaging surface of each flange, the hem including a portion of the top surface folded back on itself, and a plurality of welds securing the lid to the pan. The welds extend between the portion of the top surface of the lid folded back on itself of each hem and the respective lid engaging surface of each flange and are thereby concealed.

A stack assembly having a battery tab with a localized weld and method of making the same is disclosed. The assembly is made by a process including the steps of arranging a plurality of battery tabs into a stack assembly; providing a resistive coating on at least one of the interior surfaces and the exterior surfaces of the battery tabs; and resistive heating the stack assembly. The resistive coating is a nickel-phosphorous (NiP) alloy containing 5 to 7 weight percent phosphorus. Resistive heating includes reacting the NiP alloy with an electric current to generate concentrated heat localized between adjacent battery tabs such that the NiP alloy undergoes solid-state bonding with the Cu in the first batter tab.
