摘要： A portable plasma cutting apparatus for coping and cutting pre-bend tubular members includes a control unit, a control arm, a first step motor, a second step motor, a linear drive mechanism, a rotary drive mechanism, a plasma cutter, a tube placement deck, and a platform. The control arm is operatively coupled with the first step motor by the rotary drive mechanism to rotationally drive the control arm around a rotational axis. The control arm is operatively coupled with the second step motor by the linear drive mechanism to linearly drive the control arm along the rotational axis. A torch of the plasma cutter is terminally mounted to the control arm and positioned in between the control unit and the tube placement deck as the control arm rotationally and linearly moves about the control unit. The platform provides the sufficient height for the portable plasma cutting apparatus.

摘要： The invention relates to a welding assembly for the permanent joining of a first tubular component with a second component along a two- or three-dimensional intersection curve, along which both components contact, comprising a securing assembly for detachably securely joining on a tubular end of the first component facing away from the intersection curve, a manipulator unit mounted directly or indirectly on the securing assembly such that it can pivot about a tube longitudinal axis assigned to the first component. The manipulator unit has a freely positionable manipulator end, with a welding tool attached to the freely positionable manipulator end. The securing assembly comprises a clamping module that can at least partially be introduced into the tubular end of the first component on the end side and in an axial manner. The clamping module is detachably securely to a tube inner wall of the first tubular component, as well as a carrier ring module which is rotatably attached to the clamping module, which axially extends beyond the tubular end of the first tubular component.

摘要： Methods and apparatus to communicate via a welding arc are disclosed. An example welding-type power supply includes a power converter, a weld monitor, and an arc modulator. The power converter outputs welding power to sustain a welding-type arc at a welding-type torch. The weld monitor monitors one or more aspects of a weld performed using the welding-type arc and the welding-type torch, and selects an audio message based on the one or more aspects. The arc modulator configured to modify the welding-type arc to output the selected audio message as a plasma speaker.

摘要： The plasma torch has a nozzle and body. The nozzle has an inner nozzle and inner cap fastened to the body with the inner nozzle. Annular water passage and a plurality of independent water passages are formed between the inner nozzle and inner cap. Force applied when the inner cap is fastened to the nozzle base is transmitted via partitions. The torch body has a water supply port and drain port. At least one of the water supply port and drain port is configured as a groove extending on a plane crossing the axis and is connected to the water passage. When the nozzle is fastened to the torch body, one of the independent water passages communicates with the water supply port and another communicates with the water drain port. Rear end surface of inner nozzle is in contact with end surface of the nozzle base thereby obtaining electrical conductivity.

摘要： A method of remanufacturing a fluid end block having a plurality of segments adapted to receive working fluid includes removing at least one damaged segment from the plurality of segments of the fluid end block. The method also includes providing at least one replacement segment at a location of the at least one damaged segment. The method further includes providing a seal between a first surface of the at least one replacement segment and a first surface of at least one adjacent segment of the plurality of segments. The method includes coupling the at least one replacement segment with the at least one adjacent segment to form a remanufactured fluid end block.

摘要： A plasma cutting apparatus includes a housing, a workpiece support, a movable plasma nozzle, and a nozzle drive arrangement. The housing includes a base, an upright pedestal extending upward from the base, and a stationary head cantilevered from the upright pedestal. The workpiece support extends from the upright pedestal and is located below the stationary head. The nozzle extends downward from an underside of the stationary head and is oriented for delivering a cutting plasma generally along one direction and toward a workpiece on the workpiece support. The nozzle drive arrangement is mounted to the stationary head and is connected for moving the plasma nozzle during a cutting operation.

摘要： A plasma-torch cutting machine gantry moves in a first axis and the torch mounted through a pantograph to a drive box moves along the gantry in a second axis. The drive box rotates the torch about a third axis, and tilts the torch about a fourth axis. The drive box moves vertically in a fifth axis. The torch is mountable with tip at pantograph focal point or in an extended position. A controller firmware computes and apply offsets in the first, second and fifth axis to maintain the plasma torch tip in desired position despite the torch being mounted in extended position, rotation and tilt of the torch. In embodiments the torch is rotatable −/+90 degrees from vertical; and a laser scanner maps surfaces and edges of beams to determine movements and rotations for cutting beams.

摘要： Recognizing interchangeable torch components, such as consumables, for welding and cutting torches includes determining that one or more interchangeable torch components installed in an operative end of a torch are genuine. Operational parameters for the one or more interchangeable torch components can also be determined. When the one or more interchangeable torch components are determined to be genuine, an indicator assembly can be activated to provide a first indication. When the operational parameters are implemented at a power supply connected to the torch, the indicator assembly can be activated to provide a second indication.
