Study On Raising Efficiency And Saving Energy Of Arc Welding

China is the big country of energy produce and consume in the world. At present, the energy construction of our country is facing the rigorous situation although obtained the achievement that the whole world focuses attention. Generalizing that the reserves of average everybody can mine is low, the need increases quickly, the supply and storing keep the strain, the efficiency of use is low, the waste and the pollution is serious. For these, it is China's energy police that to step up the building of a resources-saving society, put equal importance on the development and conservation of resources while giving priority to conservation.Welding, arc welding specially, consumes electronic energy hugely. It has Important meaning that raising efficiency and saving energy of arc welding. Raising efficiency and saving energy include the both side: the first is raising efficiency, and then the exaltation rate of production, the second is economy energy, then economize the electric power and material depletions. raising efficiency and saving energy of arc welding can be carry on from the following several aspects: select raising efficiency and saving energy's welding equipments, select advanced welding craft and design the reasonable form of contact and groove, adopt low splash and high efficiently welding material. Although along with the adjustment of the our country industrial structure, the application of welding materials, equipments and crafts that raising efficiency and saving energy are increasing gradually, its total scale is so low that can't satisfy the request of building a resources-saving society. The paper researches task of raising efficiency and saving energy of arc welding, which has major engineering value and significance of theory.The paper researched on following problems: first, make use of the value engineering theories to the problem on raising efficiency and saving energy of arc welding has carried on the theories analysis. combined to long transfer pipeline engineering to optimize the welding craft of raising efficiency and saving energy to pipeline steel that is the big caliber, big thick and high strength, and carry on the analysis and count on saving energy. Second, researched an arc welding transformer of saves energy in idle hours, as well as, tested and calculated to it.The value engineering is a modern management technique that put together on technique and economies while giving priority to economic and social performances. It is a science method, which take raising the research object's value as purpose, the function system's analysis as core, creationary thinking and making use of the collective intelligence resources as the foundation, carrying out the research object's necessary function with the lowest whole lifespan period cost. Value engineering induced in arc welding field by the paper firstly, it presents theoretical guide for...
