　　Hebei wire feeding wheel small make up to tell you the development trend of welding technology

　　1, improve welding productivity is an important driving force to promote the development of welding technology

　　Ways to improve productivity are two: first increase welding deposition rate, three wires submerged arc welding, for example, the process parameters, respectively 220 a / 1400 v, 1400 a40v, 33 a45v. Using small groove section, behind setting baffle or gasket, 50 ~ 60 mm steel plate can be a fusion of forming, welding speed can reach, more than 0.4 m/min, the deposition rate compared with electrode arc welding in more than 100 times, the second way is to reduce groove profile and metal deposition, the most outstanding achievements in the recent ten years is the narrow gap welding. Narrow gap welding with gas shielded welding machine, on the basis of the use of single, double wire, three wire for welding, however, the thickness of the joint can be in the form of docking, such as the thickness of the steel plate for 50 to 300 mm, clearance can be designed for about 13 mm, so the amount of deposited metal into 7 times, dozens of times to reduce, thus greatly improve the productivity. Between narrow welding on both sides of the main technical key is to see how to ensure the penetration and ensure arc center automatically track and in the groove center line, therefore, developed a variety of solutions for different countries around the world, thus appeared a variety of narrow gap welding.

　　Electron beam welding, plasma welding, laser welding, butt joint, can be used and need not open groove, so it is more narrow gap between the ideal welding method, which is one of the reasons it widely attention.

　　The latest successful development of composite laser arc welding method can improve the welding speed, such as 5 mm steel plate or aluminum plate, welding speed can reach 2 ~ 3 m/min, and obtain good forming quality, the welding deformation is small.

　　2, improve the preparation workshop mechanization and automation level is the current focus direction of the advanced industrial countries in the world.

　　In order to improve the production efficiency and quality of welding structure, just start from welding process has certain limitations, so the world special attention to the technological transformation of the workshop. Preparation workshop main process including material transport, material surface to oil, sand blasting, coating protection paint; Steel plate marking, cutting, open groove; Parts assembly and solid. The above processes have been used in modern factories mechanization and automation. Its advantage is not only improve the productivity, more important is to improve the quality of the product.

　　3, the welding process automation

　　Intelligence is to improve the stability of welding quality, solve the important direction of poor Labour conditions.

　　4, the development of emerging industry constantly promote progress of welding technology.

　　Welding technology since the invention of over hundred years history, it can satisfy almost all the important products in the current industrial production and manufacturing needs. But the development of emerging industry still forced welding technology forward. The development of microelectronics industry promote the development of micro connection technology and equipment; And as ceramic materials and composite materials to promote the development of the vacuum brazing, vacuum diffusion welding. The development of aerospace technology will promote the development of space welding technology.

　　5, heat source of research and development is the fundamental force to promote the development of welding technology.

　　Welding process using almost everything in the world can take advantage of the heat source, including flame, arc, resistance, ultrasonic, friction, plasma, electron beam, laser, microwave, etc. (we are mainly composed of arc welding, resistance welding automation welding equipment), in the history of the emergence of each heat source is accompanied by the emergence of new welding technology. But, so far the research and development of welding heat source has not terminated.

　　6, the energy conservation technology is a problem of widespread concern

　　Consumption energy, as is known to all, welding to welding rod arc welding, for example, each about 10 KVA, submerged arc welding machine for each 90 KVA, resistance welding machine can be as high as thousands of KVA, the emergence of many new technology is to realize the energy saving target. In resistance spot welding, the use of the development of electronic technology, the ac spot welding machine into a secondary rectifying spot welding machine.
