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 relates to the technical field of positioning devices, in particular to an efficient positioning device special for accurate positioning of a flange, which comprises a positioning frame and further comprises a pipe clamping mechanism used for being connected with a to-be-welded pipeline and monitoring the connection tightness with the to-be-welded pipeline in real time, a swing frame rotatably mounted on the positioning frame, a movable fastening frame mounted on the swing frame, and a clamping mechanism mounted on the swing frame and used for clamping the to-be-welded pipeline. A rotatable rotating frame is installed on the fastening frame, an expanding and supporting mechanism is installed on the rotating frame, and two position-adjustable clamps and two position-adjustable transmission clamps are connected to the expanding and supporting mechanism. Multiple clamping modes are adopted for cooperative work, the problem that an existing clamping mode is single and unreliable is solved, the inner supporting block, the pressing block and the inner clamping face on the clamp can select to conduct clamping from the inner wall or the outer wall according to the flange type, the clamp is suitable for multiple flange types such as flat welding, butt welding, socket and sleeve loosening, and clamping equipment does not need to be frequently replaced.

Large-span corrugated steel web composite beam and construction method thereof
The invention provides a large-span corrugated steel web composite beam and a construction method thereof. The composite beam adopts section prefabrication and field assembly, and a composite abutted seam system is creatively adopted between beam sections. Butt welding is adopted for corrugated steel webs between beam sections, glue seams are adopted for concrete, and shear key teeth are matched, so that the self-alignment performance and the interface shear bearing capacity of a matching surface are improved; wave-shaped abutted seam notches are formed in the upper portions of the concrete top plate and the concrete bottom plate, concrete above abutted seams is a continuous pouring body, the waterproof performance is durable and reliable, and the long-term safety and the service life of the structure are effectively guaranteed under the condition that a waterproof leveling layer is not arranged. And in addition, the concrete in the notches is pre-pressed through the tensioning external prestressing procedure after the beam bodies are closed, the concrete at the abutted seams is further compacted, and super-strong durability is provided. A concrete waterproof layer does not need to be independently arranged on the main beam structure, the second-phase dead load borne by the main beam is effectively reduced while the work amount is reduced, and economic benefits are remarkable.
