A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.

A rollout wheel apparatus for performing welding. The rollout wheel apparatus may comprise a mount; a support section; a spindle extending from the support section; a substantially circular hub disposed on the spindle and free to rotate about the spindle, the hub having a narrow portion facing the support section and a wide portion facing the chuck, the hub further including a brake pad disposed about the circumference of the narrow portion; a brake, the brake being affixed to the support section and having a cantilever design, wherein the brake is cantilevered from the support section to a point located radially outwards from the brake pad of the substantially circular hub; and a chuck, the chuck comprising a chuck locking mechanism and a plurality of jaws.

The axle welder can be easily configured and adjusted to accommodate axle assemblies of varying axle shaft lengths, hub styles (“straight” and “drop axle”) and lug bolt configurations. The axle welder uses a sliding carriage that slides along the support frame at one end of the welder to accommodate differing shaft lengths. The axle welder also includes a pair of pivoting hub lifts that accommodate both straight and drop axle style axle hubs using modular mounting plates. Modular mounting plates (“hub adaptors”) fitted to the hub lifts accommodate hub assemblies with differing lug bolt patterns. The axle welder is built on a rectangular frame that supports a pair of weld units and articulated electrode arms. The axle welder also includes a pair axle supports for carrying the axle shafts within the support frame. A shaft drive pivotally mounted to the support frame lowers to engage and rotate the axle shaft and hub assemblies in unison during the welding process.

A desktop laser cutter configured to cut a cylindrical workpiece includes a laser, a cutting head that receives an electromagnetic beam from the laser and emits a cutting beam, and a gantry that supports the cutting head relative to a base plate of the laser cutter housing. The gantry can be actuated to move the cutting head within a plane that is parallel to the baseplate. The cutting head emits the cutting beam in a direction parallel to the plane. In use, the cutting head is disposed side-by-side with the workpiece and the cutting beam is applied to a side of the workpiece that faces a sidewall of the laser cutter housing. The workpiece is supported by the gantry to rotate an amount that is a function of movement of the cutting head in a direction parallel to the plane.

A collar flange assembly welding fixture is disclosed, including a stand, a circular mount structure, and a support assembly which are configured to provide access to a front side and a back side of a collar flange assembly held by the support assembly. The stand has a plurality of circumferential bearings equidistant from an axis of rotation, the circular mount structure is rotatably supported by the circumferential bearings, and the support assembly is configured for mounting on the circular mount structure.

The automatic welding method includes: carrying a pipe on which a true circle weld groove and settling the pipe at a fit-up position in the welding station and carrying a hollow connection member on which a true circle weld groove is formed to a position near the fit-up position in the welding station by using the material transport robot; measuring the alignment state of the hollow connection member with respect to the fit-up position by using a gap sensor robot, and according to the results, moving the position of the hollow connection member to align the weld groove of the pipe with the weld groove of the hollow connection member; performing a root welding on the aligned weld grooves by using a GT welding robot; and performing a filling and cap welding on the aligned weld grooves by using a GM welding robot to manufacture a 2D spool.

A supporting device for supporting a workpiece for processing in a laser processing machine includes a base carrier having a guide body for fastening the supporting device in the laser processing machine, and a guide device provided on the base carrier for guiding the workpiece. The guiding device includes at least two guide elements, which are adjustable in distance to one another and on which the workpiece rests. The guide device has two slides, which are movable relative to the base carrier. At least one of the at least two guide elements is provided on each slide. The two slides are movable in coupled fashion, along two guides that are arranged at an angle to each other and are provided on the base carrier.

The invention relates to a method for handling a rectifier of a turbojet of an aircraft, the rectifier having an axis defining the asymmetry thereof, said method comprising a step of placing the rectifier on the rollers of a supporting structure, the structure and the rollers thereof being arranged such that the axis of the rectifier is inclined at a non-null acute angle in relation to the horizontal, and a step of controlling, maintaining, assembling, handling, storing, deburring and/or cleaning the rectifier, during which the rectifier is pivoted about the axis thereof. The invention also relates to a trolley for handling a rectifier for an axial turbojet, said trolley comprising at least two of the lower rollers that have axes inclined in relation to the horizontal of said angle and at least one upper roller, the axis of which is inclined in relation to the vertical of said angle.

A welding mechanism for welding different blank sections includes a welding device and a carrier. The carrier has a base, two opposite positioning members, an operating set disposed between the positioning members and driven by a power source, and a holding member and a pushing member which are respectively disposed relative to the positioning members. The blank sections, including a front section and a rear section, are separately placed on the operating set. The front section is restricted by the holding member. The pushing member pushes the rear section, so the two sections meet at a joint. When the two sections rotate synchronously along with the rotation of the operating set, the welding device welds the two sections at the joint circumferentially to produce a bi-compositional screw, thereby preventing the generation of air and pores inside the joint after welding, increasing processing quality, and reducing processing costs.
