Provided is a weld assembly supported from an arm of a heavy equipment vehicle. The vehicle includes a pipe grabber for manipulating the position of a pipe. The weld assembly integrated with and supported from the manipulator. The weld assembly further includes a conforming ring, a sensor assembly and an orbital welder. The weld assembly is also of a clam shell construction for wrapping around two pipe ends to be welded.

A method of cutting a pipe includes positioning a positioning apparatus on the pipe, moving the positioning apparatus relative to the pipe to center the positioning apparatus on the pipe, attaching a pipe machining apparatus to the positioning apparatus, and moving the pipe machining apparatus relative to the positioning apparatus and relative to the pipe.

A method for manufacturing a razor cartridge component comprises continuously feeding an elongated band of material, separating one or more blade support elements from the elongated band of material, stabilizing the one or more separated blade support elements in a stationary position; providing one or more razor blades; and laser welding the one or more razor blades to respective ones of the stabilized one or more blade support elements.

A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

An apparatus for repairing a metal sheet and method of operating the same are provided. The apparatus includes: a base unit including: a frame and an attachment feature on the frame, a cutting unit removably attachable to the base unit to cut out a damaged portion of the metal sheet, and a welding unit removably attachable to the base unit. The cutting unit includes: a cutting arm including a cutting blade, and a motor for operating the cutting arm. The welding unit includes: a fixed platform, a weld movement motor for moving a moveable platform on the fixed platform, and a welding assembly, attached to the moveable platform, to automatically weld a replacement piece to the metal sheet. In operation, the frame is continuously attached to the metal sheet during cutting of the damaged portion and welding of the replacement piece, providing a stable and repeatable frame of reference.

The present disclosure relates to a cutter clamp (8, 37) that comprises a first arm part (10, 39) and a second arm part (11, 40), where the arm parts (10, 11; 39, 40) are arcuate and arranged to adjustably at least partially enclose a major part of a circumference (57, 63) having a center (58, 64). The cutter clamp (8, 37) comprises at least one hollow rod (21, 22; 48, 62) arranged for receiving a mounting rod (36) for a power cutter (1, 56) in a pivoting manner. The smaller circumference the arm parts (10, 11; 39, 40) are adjusted for, the closer to the center (58, 64) said hollow rod (21, 22; 48, 62) is moved. The present disclosure also relates to a cutter clamp attachment device (68), a cutter clamp kit and a cutter clamp holding frame (76).

A robotic welding device employing a flexible guide rail comprises: a control box (2) pre-storing various welding processes and generating a welding parameter; a wire feed mechanism (7) feeding a welding wire to a welding gun (4); a flexible guide rail (8) attached to a welding component with the flexibility thereof; a welding robot comprising a robot body (3) and a welding gun (4), the robot body (3) being movably disposed on the flexible guide rail (8) along the same, and the welding gun (4) being disposed on the robot body (3) and controlled by the same to weld the welding component; a demonstrator (6) signally connected with the welding robot and the control box (2), controlling, a traveling path and an operation position of the welding robot, and adjusting oscillation and welding operations of the welding gun (4) according to an instruction of the control box (2); a remote control terminal (11) signally connected with the control box (2) so as to remotely monitor and configure the welding parameter, and signally connected with a data acquisition device of the welding robot so as to remotely monitor and configure the welding parameter during a welding process; and a welding power supply (1). The device enables automatic welding of a component with straight shape or arc shape.

An orbital welder for welding together two pipes to be welded. The welder includes a fall brake for preventing a freefall of the welder. The welder includes a spatter shield for preventing dust from entering the outer housing and fowling sensitive machine components. The welder includes a torch assembly with manual adjustments. The welder includes an automatic lead/lag adjustment and control of that adjustment during a welding operation to automatically transition from a first weld zone to a second weld zone.

In one aspect, a pipe machining system is provided and includes a positioning apparatus, a pipe machining apparatus, and an adjustment member coupled to the positioning apparatus and a pipe machining apparatus. The adjustment member is configured to move the pipe machining apparatus relative to the positioning apparatus. In one aspect, the pipe machining system also includes a position tracking apparatus configured to identify a position of the pipe machining apparatus relative to a pipe on which the system is mounted.

An apparatus for volume reduction of material removed from a hazardous environment. The apparatus includes a shielded housing for receiving a workpiece therein, at least one cutting unit having a cutting head operable for contactless cutting, and a drive unit for rotating the at least one cutting unit around a main axis so the cutting head cuts the workpiece.
