A welding fixture and method allow for both coarse and fine adjustments of headstocks and tailstocks for securing a tank or other cylindrical-like object within a welding fixture. Coarse adjustment is provided by adjusting the headstock and/or tailstock linearly along a rail system. Find adjustment is provided by linearly adjusting a movable table on which the headstock and/or tailstock rest. The headstock and tailstock may also have compression clamping members for securing the tank to the headstock and tailstock. Pipe stands are also provided for supporting the tank before, during, and after the welding process.

A first rod (21) is inserted into a first guide hole (11) so as to be movable in a vertical direction. A second rod (22) is inserted into a second guide hole (12), which crosses the first guide hole (11), so as to be movable in a horizontal direction. An accommodation groove (31) is disposed in a lower half portion of the first rod (21). The second rod (22) is provided with an insertion portion (32) to be fitted in the accommodation groove (31). A cam groove (38) provided in the insertion portion (32) is fitted over a pin (35) provided in the lower half portion of the first rod (21). A driving means (D) connected to the second rod (22) moves the second rod (22) in the horizontal direction.

The present invention provides a work piece processing system for operating on a work piece or at least one component of a work piece. The processing system includes a base system for transporting the at least one work piece component, at least one processing head for operating on the work piece component, and means for controlling, the means for controlling the processing system. In a first embodiment, the processing system further includes a support structure, the support structure including at least one frame member having a track. Here, the at least one processing head travels along the track. In a second embodiment, the processing system further includes a multi-linkage robotic arm, the robotic arm including a plurality of rotary joints and a plurality of arm segments interconnecting the rotary joints. Here, the at least one processing head is operably mounted to a free end of one of the plurality of arm segments.

Method and device for centering and temporary fixation of tube parts (1, 5) in relation to each other's interior surfaces. A first tool (9) is centered relative to a tube part interior surface (2, 6) by a radially adjustable centering mechanism (13). The centering mechanism (13) is insertable in the tube part (1, 5). A second tool (10) is centered relative to the first tool (9), by a guiding mechanism (15) which cooperates for centering of the tools (9, 10) relative to one another. The second tool comprises fixing mechanism (17) to fix the exterior surface of the tube part (1, 5) to the second tool (10), and at least one third guide (18) which centers two such second tools (10) relative to one another in their mounted position on respective tube part end (4, 8) and at least one coupling member (19) to connect the two second tools (10).

A system to remove a ram packer from a ram block is provided. In one embodiment, the system includes an extraction tool having opposing jaws configured to engage a ram packer installed in a ram block. The system may also include an actuator configured to move the opposing jaws to facilitate separation of the ram packer from the ram block. Additional systems, devices, and methods are also disclosed.

A method of joining a first pipe section to a second pipe section includes positioning the two pipe sections in an end-to-end configuration to define therebetween a joint to be welded, measuring the degree of alignment of the pipe sections when they are in the end-to-end configuration in a position ready for welding, ascertaining the relative movement required of the pipe sections in order to improve their alignment, effecting the relative movement so ascertained, and welding together the two pipe sections. The method may include the use of geometric data of the end of the pipes in order to ascertain the relative movement required of the pipe sections. A control unit may be used to calculate, using such data, a target orientation that lines up the pipe sections. The measuring step may be performed using, for example, a laser or a camera and backlight.

In a device for separating a longitudinally-extended cylindrical workpiece, which has a diameter in the sub-millimeter range, into individual segments, the workpiece is guided in a clamping device. The clamping device includes a first and a second clamping jaw and a feed opening for the workpiece. The feed opening is fitted between the clamping jaws on the side facing the other clamping jaw and a longitudinal groove which defines a direction of advancement of the workpiece for receiving and guiding the workpiece between the clamping jaws. The clamping device has a passage for a laser beam and a cutting gas, which passage defines a working zone, disrupts the longitudinal groove and runs parallel thereto. A cutter head is arranged in the working zone and has an outlet opening for the laser beam and the cutting gas, which outlet opening is aligned with the passage.

Apparatus for controlling a welding station used for welding seams extending along cylindrical can bodies, the welding station comprising a pair of welding rolls and a calibration unit for causing a desired cylinder overlap during welding. The calibration unit is adjustable along at least three different adjustment axes. The apparatus comprises: a weld monitor configured to monitor welded seams and provide an electrical signal indicative of weld thickness at a series of predetermined points along the seam length; a controller configured to receive said signal and to generate one or more control signals; and adjustment mechanisms for coupling to the calibration unit, or forming part of the calibration unit. The adjustment mechanisms are configured to receive the signal(s) and to be responsive thereto to adjust the calibration unit relative to one or more of said three adjustment axes, to provide the desired cylinder overlap and/or a desired weld quality.

The present invention relates to the repair of pipes, comprising a two-part ring fixed initially by a compression unit which allows the execution of longitudinal welding in order definitively to fix the two-part ring, via apertures, before the compression unit is removed. The two-part ring will be completely welded to the pipe, especially in regions close to connections, but it is necessary for the two-part ring to be fixed initially by the compression unit for the purpose of shaping and definitive geometry of the ring relative to the pipe, normalization of fluid conveyance and in order that it is possible for welding to be planned for the opportune moment.
