The invention relates to an assembly for automatic aligning of rails, comprising: a first alignment system (10) suitable for placing on a first track element (70) on a first rail (100); a second alignment system (20) suitable for placing on a second track element (70) on a second rail (200); and a system for acquiring a position (30), comprising at least one position sensor, wherein the first alignment system (10) and/or the second alignment system (20) comprises an actuating system (51, 52) suitable for automatically adjusting a position of the first rail (100) and/or of the second rail (200) on the basis of a position measured by the acquisition system (30).

A Mobile Electric Flash-Butt (EFB) Welding apparatus that incorporates an automated geometry system which creates field/mobile EFB welds with proper vertical alignment, within a definable distance. The system has a first pair of adjustable reference points on a left side of a mobile welding apparatus. The system has a second pair of adjustable reference points on the right side of the welding apparatus. The system has a first lifting mechanism positioned between the first pair of adjustable reference points and a second lifting mechanism positioned between the second pair of adjustable reference points. The welding line is positioned between the first and second pair of adjustable reference points and is the location of the weld. The system allows for comparatively shorter inserts than previously utilized.

Provided is a fabrication square for aligning workpieces. The square includes a triangular shaped base, a first arm, a second arm, and a relief cut where the arms intersect the base. The arms extend away from the base at a 90-degree angle. The base and first arm further include a series of holes that match the hole pattern found on a conventional metal fixture table, while the second arm includes a slot to allow for rotation. The square can be aligned with and attached to the fixture table with one or more fixture stops that secures the square to the table via the holes. The use of the square, fixture stops, and table lock the workpieces in position, which in turn prevents movement before, during, and after welding, thereby increasing fabrication precision.

A five axis welding positioner has a horizontally oriented indexing axis for indexing a welding part between workstations. The indexing axis corresponds to a first axis of rotation. Each workstation has a C shaped frame for holding a welding part and may be tilted about a tilting axis. The tilting axes of each workstation correspond to second and third axes of rotation. Each C shaped frame has a head stock and tail stock that can rotate the welding part about a rotation axis. The rotation axes correspond to fourth and fifth axes of rotation. Movement about each axis can be effectuated by an actuator such as a motor.

A device for positioning a number of function elements, each having a recess for a shaft, in a predetermined angle position on the shaft, may include a plurality of support balconies arranged one above the other, each being destined for a function element. A movable guide carriage may be configured to enable the shaft to be push the shaft from above through the recesses of the function elements. The support balconies may each include at least one gripper respectively fixing one function element. The at least one gripper may be arranged on an associated gripper carriage and may be adjustable in an x-direction and a y-direction relative to the associated gripper carriage and the support balcony. The associated gripper carriage may be mounted on the support balcony so as to be rotatable about a z-axis.

This invention discloses a welding equipment for bridges, comprising a base, a fixed ring stand arranged on the top end surface of the base, a fixed block fixedly arranged on the bottom end surface of the fixed ring stand, wherein a first guide sliding groove is arranged in the top end surface of the base, a first guide sliding block in sliding fit connection with said first guide sliding groove. A welding ring stand is fixedly connected to the top end surface of said first guide sliding block; wherein a first adjusting threaded rod is in threaded fit connection with the first guide sliding block. A first motor is in power connection with one tail end of the first adjusting threaded rod. The first motor drives the first adjusting threaded rod to rotate to make the welding ring stand move to one side.

A welding device for automatically welding a workpiece by a welding robot using a welding wire includes a welding control device that controls operation and welding work of the welding robot. The welding control device includes a sensing unit configured to detect a position of the workpiece, a root gap calculating unit configured to determine a root gap, and a storage unit including wire melting information as a database of a proper welding current corresponding to a feeding rate for each of the welding wire. A lamination pattern and a welding condition are provided in accordance with the root gap determined by the root gap calculating unit and the wire melting information so that an amount of heat input is equal to or less than a predetermined amount of heat input.

A method of bonding a flexible part including inclined leads is provided, and more particularly, a method of bonding a flexible part including inclined leads, in which parts are aligned to bond the parts is provided. According to the method of bonding the flexible part including inclined leads, an electronic part may be easily bonded to a part having an inclined surface.
