焊接新技术新工艺研究.docVIP

摘 要 随着科学技术的不断发展，焊接新技术新工艺也不断成熟与创新使其应用越来越广泛。在机械制造、航空航天、石油化工、能源、交通、建筑、冶金等领域使用的金属结构都属于焊接结构，在加工过程中都离不开焊接。工业的发展，具有特殊性能的新型结构材料不断涌现，对焊接技术的要求也越来越高，因此焊接新技术新工艺的发展情况也越来越受到关注。文中先从焊接技术和材料开始介绍，以此为前提再通过对典型金属材料的焊接新技术新工艺讲解入手，着重介绍焊接技术及工艺在原有水平及基础上的必威体育精装版发展状况，指出了这些焊接新技术新工艺的内容及应用状况，并对焊接技术和工艺做出了适当的展望。 关键词：新技术，新工艺，金属材料，焊接方法Abstract With the development of science and technology, welding new technology new technology has been matured and innovation make the application more and more widespread. In machinery manufacturing, aerospace, petrochemical industry, energy, traffic, building, metallurgy and other fields used metal structure belongs to the welding structure, in the process without welding. The development of industry, has the special property of new structural materials continue to emerge, the welding technology requirements are also getting higher and higher, so the welding new technology new technology development is paid more and more attention. The article first from the welding technology and materials is introduced, taking this as the premise and the typical metal material welding new technology new technology on proceed with, introduced emphatically the welding technology and process in the original level and on the basis of the latest development, pointed out these welding new technology new technology content and the application condition, and to welding technology and process to make appropriate prospect. Key word: New technology, New process, Material, Welding method 目 录 前 言.................................................................1 1 金属焊接材料及技术简介...............................................2 1.1 焊接材料作用及种类................................................2 1.1.1 焊接材料的作用 2 1.1.2 新型焊接材料简介 4 1.2 金属焊接技术简介及现状............................................5 1.2.1 焊接技术简介 5 1.2.2 金属焊接技术现状 8 2 金属焊接新技术和新工艺...............................................9 2.1 珠光体耐热钢的焊接新工艺..........................................9 2.1.1 焊前分析 9 2.1.2 焊接新工艺 9 2.2 奥氏体不锈钢的焊接............................
