    摘要： A weld overlay machine assembly includes a carriage to support a hinged index bar and a wire feed assembly. The index bar has an auto height control unit and an index assembly to locate the position of a weld torch relative to the index bar. The assembly is configured to adjust the index bar to interior contours of the vessel while applying a layer of overlay material to a surface therein. The assembly runs along a track in the interior of the vessel. The assembly is configured to transition from sides of the vessel to that of the top or bottom domes wherein the curve of the domes are perpendicular to that of the radial sides. This transition is done without the need to add or remove components to the assembly. This is accomplished by providing the pivoting of the index bar relative to the track.

    摘要： A robotic electric arc welding system includes a welding torch, a welding robot configured to manipulate the welding torch during a welding operation, a robot controller operatively connected to the welding robot to control weaving movements of the welding torch along a weld seam and at a weave frequency and weave period, and a welding power supply operatively connected to the welding torch to control a welding waveform, and operatively connected to the robot controller for communication therewith. The welding power supply is configured to sample a plurality of weld parameters during a sampling period of the welding operation and form an analysis packet, and process the analysis packet to generate a weld quality score, wherein the welding power supply obtains the weave frequency or the weave period and automatically adjusts the sampling period for forming the analysis packet based on the weave frequency or the weave period.

    摘要： A tool bit with a surface layer metallurgically bonded on a substrate layer using electrospark deposition (ESD) that allows the tool bit to reduce camout and engage a fastener head for one-handed starting and removal. The surface layer has a rougher finish, compared to conventional tool bits, and therefore better grips engagement surfaces of a mating recess of the fastener during use. The reduction of camout provides greater durability to the tool bit and resists erosion and wear of the engagement surfaces of the fastener.

    摘要： A welding or additive manufacturing wire drive system includes a welding wire spool and first and second drive rolls. One or both of the drive rolls has a circumferential groove. The system includes a first welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove, and a second welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove, and the second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.
