The invention provides a large-size aluminum-steel reaction auxiliary heating and toughening friction welding method. According to the method, two-way embedded structure design is conducted on a welding joint of an aluminum component (20) and a steel component (10), and a welding auxiliary layer is arranged at the welding joint. According to the two-way embedded structure design, specifically, an annular steel inner groove (11), an annular steel boss (12) and an annular steel outer groove (13) are sequentially machined in the to-be-welded face of the steel component (10) from a center shaft to the outside, and an annular aluminum groove (21) is machined in the to-be-welded face of the aluminum component. The welding auxiliary layer comprises a reaction transition layer (51), a reinforcing and toughening layer (52) and a reaction auxiliary heating layer (53). The method effectively solves the problems that in the welding process of the steel component and the aluminum component, a large number of brittle intermetallic compounds are likely to be generated, the stress of a welded joint is large, the strength of the welded joint is low, and toughness is poor, friction welding between the large-size aluminum component and the large-size steel component is achieved, the welding efficiency is high, and the welding quality is good.

The invention relates to an open arc on-line surfacing repair device and method for a grinding roller of a medium-speed mill. The open arc on-line surfacing repair device comprises a PLC welding control box, and an electric welding machine, a welding trolley, a double-drive wire feeder and a limit switch which are connected with the PLC welding control box. A grinding roller driving device is arranged at the bottom of the grinding roller; a welding gun is arranged on the surface of the grinding roller; the rear end of the welding gun sequentially communicates with the double-drive wire feederand a welding wire straightening mechanism through a connecting rod; a welding wire placed on a wire feeding device penetrates into a wire inlet of the welding wire straightening mechanism; and the double-drive wire feeder is mounted on the welding trolley through a welding gun angle adjusting mechanism. On-line surfacing repair is carried out on the grinding roller without disassembling the grinding roller, so that a large amount of manpower and material resources are capable of being saved and the repair period is capable of being shortened. The open arc on-line surfacing repair method mainly ensures that each performance of a surfacing layer meets repair requirements by selecting welding parameters and welding modes.

The invention relates to a welding processing technology for a copper pipe of an air conditioner condenser,which uses a welding processing device for the copper pipe of the air conditioner condenser. The welding processing device for the copper pipe of the air conditioner condenser comprises a bottom plate, a moving mechanism, an adjusting clamping mechanism, a fixing mechanism and a pushing mechanism. According to the adjusting and clamping mechanism, the U-shaped copper pipe only needs to be placed in a first clamping groove plate and then is conveniently matched with the moving mechanism, the angle of the U-shaped copper pipe is adjusted, and the phenomenon that safety cannot be guaranteed when the U-shaped copper pipe and a condenser copper pipe connecting piece plate are welded in a manual mode is avoided; and meanwhile, an I-shaped plate is adopted to be matched with a baffle, so that the position between a first moving plate and a second moving plate after angle adjustment is completed is determined, welding forming of a next set of condenser copper pipe connecting piece plates with the same angle is facilitated, and the complexity that adjustment needs to be conducted each time before use is avoided.

The invention discloses a steel strip feeding mechanism and a welding robot provided with the same and relates to the technical field of steel strip transmission. The steel stripe feeding mechanism comprises a rack, a guide rail, a limiting part and a feeding part, wherein the guide rail is arranged on the rack in the feeding direction of the steel strip; the limiting part is fixed to the guide rail and can limit the steel strip to move in the feeding direction; the feeding part is slidably arranged on the guide rail, and the steel strip can be fixed to the feeding part and can move along withthe feeding part. The welding robot comprises at least one steel strip feeding mechanism. According to the steel strip feeding mechanism, when the feeding part is relatively far from the limiting part, the limiting part fixes the steel strip, the feeding part slides toward the direction close to the limiting part, then the steel strip is fixed to the feeding part, the limiting part loosens the steel strip to feed the steel strip toward the feeding direction along with the feeding part, and the limiting part and the feeding part are matched to transfer the steel strip gradually, so that the steel strip meshes are welded and formed conveniently.

The invention relates to a process for welding reinforcing rings between a topside module and a jacket. The process includes the following steps: (1) one reinforcing ring serves as a unit, and welding prefabrication of the reinforcing rings and internal flange rings is carried out on the exterior of the jacket and the exterior of the topside module; when prefabrication is carried out, one reinforcing ring is divided into a plurality of arc-shaped plates, and then the multiple arc-shaped plates are spliced together to form the overall reinforcing ring; (2) the flange rings are placed on a potension meter, and are welded to the arc-shaped plates through a submerged arc welding machine to conduct pairing; (3) K-shaped notches are formed in the edges of the outer sides of the reinforcing rings, the flange rings are clamped through clamps, and then the reinforcing rings are placed into pipes to conduct pairing; (4) reputedly executing the step (1) and the step (2) until the overall welding process is completed. By means of the process, a large amount of in-pipe welding work is avoided, the operation environment of an operator is improved, and the operation safety is greatly improved. In addition, the requirement for operating skills of the operator is greatly reduced, and the construction efficiency is greatly improved.
