Butt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. Butt welding can also be done with brazing for copper pieces. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. A flange is something that either is internal or external that provided to strengthen a piece of material. In factories butt welding has shown how economical it can be for companies to use when building things out of metal. This is because if they wanted to make something out of metal without welding it together they would have to bend everything and reinforce the structure which costs more than welding the two pieces together. Butt welding is accomplished by heating up two pieces of metal, or applying pressure, or doing both of those. Penetration while welding the metal is important to maintain and with thin pieces of metal this is possible however, with thick pieces edge preparation may have to be done to prepare the metal. Full penetration butt welds are made when they are in the within the parent(bigger, stronger) metal. In butt welding the strongest welds will have the fewest imperfections. To achieve this the heat input is controlled, which decreases the size of the weld. In commercial welding when this is done it also reduces cost but in order to maintain the strength of the weld double butt welds will be used. In butt welding there are two types used to achieve the specific welds and then there are also a variety of joints considered to be butt joints.

The invention discloses butt welding equipment for electric vehicle hub production, which belongs to the technical field of welding and comprises a workbench, a forming cylinder, a guide column and a welding gun. A working face is arranged on the surface of the workbench and used for placing a plate as a basic blank for forming the hub outer frame. The forming cylinder is arranged above the workbench, and the arc surface of the forming cylinder serves as a forming surface, so that a plate is tightly attached and bent into an annular body. The two guide columns form pressure applying tracks on the two sides of the forming cylinder and move along the arc face, a plate is bent and attached to the surface of the forming cylinder, and the two ends of the plate are connected to form a welding line. And the end part of the welding gun can move along the welding line to finish welding. A plurality of adsorption openings communicated with the air suction channel are formed in the surface of the forming cylinder, adsorption force is applied to the plate, and movement or dislocation is prevented. A sealing ring is arranged on the periphery of the adsorption opening to improve sealing performance. A supporting plate and a ventilation hole are arranged in the adsorption opening, the structure of an air suction channel is optimized, the air suction efficiency is improved, and uniform distribution of adsorption force is ensured.

Band flash butt welding machine and group of accessories for a band flash butt welding machine
PendingUS20250073806A1Metal sawing tool makingWelding/cutting auxillary devicesButt weldingFlash light
Various embodiments relate to a band flash butt welding machine by which it is possible to weld band faces of band ends of at least one band, in particular a saw band, to each other. The band flash butt welding machine comprises clamping elements for clamping the band ends. Furthermore, the band flash butt welding machine comprises aligning elements for aligning the band ends. The second clamping elements can be moved by a drive relative to the first clamping elements in the direction of a longitudinal axis. Two aligning elements are fixedly connected to one another by a coupling device, in particular a bridge part. The coupling device defines the relative alignment of the aligning elements. The second clamping element can be moved relative to the two aligning elements. This design is advantageous for a changeover of the band flash butt welding machine for band ends having a different geometry.
