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.

Disclosed is a rotary actuated axial clamp that includes a primary fixture, having a rotatable primary clamp, having primary clamp fingers that engage secondary clamp fingers on a stationary secondary clamp. The primary fixture is attached to a positioner, while the secondary fixture is attached to the work piece. Different secondary fixtures can be utilized to fit the shape and size of the work piece, while maintaining a secondary clamp that is able to engage the primary clamp of the primary fixture. The primary fixture can consequently be utilized with numerous different work pieces having different shapes and sizes by simply modifying a secondary fixture to adapt to the size and shape of the work piece. Roller engagement of the primary clamp and secondary clamp reduces the force required to clamp and unclamp the primary and secondary fixtures. This reduces problems associated with attaching a work piece to a positioner.

Control method of a welding device having an upper tool, lower tool, control unit and welding device positioning arrangement for a drive system having no or little mechanical losses. In the method, the lower and upper tools are moved relative to each other, the drive system of the positioning arrangement presses first and second components against each other and, during the actuating of the drive system, a force is measured at a static first section (and/or a position of a movable second section of the positioning arrangement relative to the static first section). The measured force and/or position is compared with a predetermined force and/or position, and actuating is stopped after the predetermined force and/or position has been reached. Subsequently, the first and second components are welded to each other, the drive system is actuated, and the lower and upper tools are moved relative to each other.

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 tool welding system is disclosed that includes a table that heats a tool. A multi-axis robot includes a welding head that is moved relative to the table in response to a command. A controller is in communication with the robot and generates the command in response to welding parameters. The weld parameters are based upon a difference between an initial tool shape and a desired tool shape. The difference between the initial tool shape and the desired tool shape corresponds to a desired weld shape. The desired weld shape is adjusted based upon initial tool shape variations, which includes thermal growth of the tool. The tool is welded to provide the desired weld shape to achieve a desired tool shape.

A roll-out wheel has a base housing secured to a working surface. A rolling arm having a lever end and a working end pivots about a hinge point in the housing. A hand wheel and a pipe chuck are rotatably attached to the working end by a rolling sleeve. A pipe to be welded is securable on the pipe chuck and rotatable in unison with the hand wheel. Rotation of the hand wheel permits welding about the perimeter of the pipe without moving the welding tool. A clamping mechanism can permit or prevent rotation of the hand wheel. A pivoting mechanism can raise or lower the working end.

A device for the laser treatment of trousers, including a laser beam generating equipment suitable for emitting the laser beam in any direction within an emission pyramid with an emission axis and two opening angles, and a work station with two mannequins, where each mannequin includes two legs. Each leg defines a longitudinal axis, and the two longitudinal axes of each mannequin define a mannequin plane. Each of the mannequins is oriented towards the equipment so that the emission axis strikes the mannequin plane at an angle of less than 90? and each mannequin has at least one of its legs within the pyramid.

A welding method includes placing a housing covered with an end cap into a jig, where a clearance structure is created on the jig and available for exposing a target weld zone between the end cap and the housing, and the target weld zone includes a first target weld zone section and a second target weld zone section located on two opposite sides of the end cap respectively; and moving the jig to a first welding station of a welding device; welding, by a first welding head of the welding device, the first target weld zone section through the clearance structure; and welding, by a second welding head of the welding device, the second target weld zone section through the clearance structure. The first welding station is located between the first welding head and the second welding head.

The invention relates to an ultrasonic welding apparatus (10) for welding rod-shaped electric conductors (17, 28, 29) which are provided with an insulating outer sheath and have bare regions (33) free of the sheath, comprising a compression space arrangement (41) having a compression space for receiving bare regions to be connected to each other, and a positioning device (42) for positioning the bare regions (33) relative to each other, the positioning device having two stop elements (46, 47) which each have a stop surface (48, 49) for axially positioning a bare region (33) in such a manner that the bare regions (33) overlap with an overlap length l in order for a weld node to be formed, wherein the positioning device (42) is remote from the compression space arrangement (41) and is provided with a transferring device (43) which has a receiving device (52) for fixedly receiving, outside of the compression space (18), the conductors (17, 28, 29) axially positioned by means of the positioning device (42), and the transferring device (43) serves to transfer the conductors (17, 28, 29) fixed in a receiving position in the receiving device (52) into the welding position within the compression space.

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.
