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.

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

A chassis welding device for welding brackets as standard members to a body of a chassis includes a frame, a first transferring member, a plurality of loading mechanisms, a plurality of carriers, a conveying member, a shifting member, and a spot welder. The loading mechanism transfers standard members to individual preset positions on the carrier to face the solder joints on the standard members away from the carrier. The first transferring member transports the carrier to the shifting member. The shifting member transfers the carrier from the first transferring member to the spot welder. The conveying member transfers the body into contact with the solder joints. The spot welder applies heat to melt the solder joints to bond the standard members to the body.

A device for descaling a metallic membrane of a tank for transporting and/or storing gas in liquid form includes: a rail secured to the metallic membrane; a head projecting a laser beam to descale the metallic membrane; a support interposed between the projection head and the rail and traveling along the rail; and a device allowing a movement with respect to the metallic membrane of a point of impact of the laser beam on the metallic membrane, the movement being different from the travel effected by the support on the rail.

This joining apparatus, which is a joining component manufacturing apparatus, comprises a pressing-force-applying means that applies a pressing force for pressing a second joining part that is formed on a second workpiece toward a first joining part that is formed on a first workpiece. The joining apparatus is provided with a laser light irradiation device that irradiates a site where the first joining part and the second joining part are brought close together with laser light. The pressing-force-applying means and the laser light irradiation device move as an integrated unit along the direction of extension of the first joining part and the second joining part due to a movement device.

A self-propelled welding station including a base frame having at least one front wheel and at least two rear drive wheels, provides and independent mobility drive system with a motor and steering means for a seated or standing operator, and a utility drive system providing a self-contained, motorized welder with welding leads for remote welding and a secondary electrical generating system providing a plurality of A/C electrical outlets, an air compressor assembly to provide compressed air to operate air tools and forced air, a plurality of accessory tool and supply storage containers, accessory equipment and a bottled gas system for welding gases, gauges and hoses. The mobility drive system motor is independent from the motorized welder so that the station may be moved whether the motorized welder is on or off, and the motorized welder may be operated with the drive motor system on or off.

A welding manipulator for holding a welding head comprised of a base, rotating column and swivel boom is shown. The column includes a novel rotating apparatus comprised of a lockable rotary bearing, rotary housing, clamp shell and brake handle. In the unlocked position, the column rotates smoothly and easily around the base. In the locked position, the clamp shell engages and disengages the rotary bearing, thus locking the column in place.

The present welding manipulator also discloses a boom attached to the column with a swivel mount. This swivel mount allows the boom to be locked into an operating position or a shipping position for more compact shipping or storage. The disclosed welding manipulator also includes tracks on the column and a motorized screw drive to vertically position the boom.

An orbital welding device includes a receiving region into which a round tubular object to be welded can be inserted. The receiving region is designed in two parts with a folding joint for folding together a closing region, and includes a welding means which is rotated about the receiving region and by which the round tubular object is welded in a revolution using an arc welding. An electrically chargeable positive pole is provided on two surrounding outer plate means comprising an aluminum clamp shell housings, and an opposite electrically chargeable negative pole, is arranged on the receiving region with the rotating welding means. A respective insulating body is arranged between the positive pole and the negative pole. The insulating body includes a 3D-printed region, produced by a plastic powder laser sintering method, with one or more conducting means for welding gas and/or one or more conducting means for cooling water.

A mobile welding system that does not rely exclusively on a track to define the path of the welder. One embodiment includes a mobile welder adapted to move along a work piece. The mobile welder includes a chassis, including a welding implement, and a travel assembly configured to support the chassis over a portion of the work piece. The mobile welder also includes a motor assembly configured to selectively cause the chassis to move relative to the work piece. The mobile welder further includes a chassis holder, having a magnet assembly, configured to provide a force holding the chassis a selected distance from the work piece. The magnet assembly includes a magnet rotatably mounted between a ferrous material and a non-ferrous material to selectively control application of a magnetic field toward the work piece.

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.
