【正文】 桂 林 航 天 工 業(yè) 學 院 I 壓力容器制造工藝研究 摘要 隨著科學技術的發(fā)展，壓力容器制造水平越來越高，壓力容器涉及多個學科， 綜合性很強，一臺壓力容器從參數(shù)確定到投入正常使用，要通過很多的環(huán)節(jié)及相關 部門的各類工程技術人員的共同努力才能實現(xiàn)。 本論文簡述了壓力容器的結構標準，主要研究了壓力容器的焊接工藝及工藝評定，在對 熔化槽槽體 進行了一定的介紹與筆者理解前提下，對 熔化槽槽體 進行了焊接工藝 的制定與焊接工藝的評定。經(jīng)過筆者查閱收集資料，闡述了壓力容器的組成結構與壓力容器標準，通過查閱焊接手冊及壓力容器工藝手冊，對壓力容器的焊接材 料與焊接工藝有了一定的了解，在老師的大力關心與輔導下完成了壓力容器的工藝 制定 與工藝評定。通過對 熔化槽槽體 焊接工藝的評定，發(fā)現(xiàn)壓力容器的制造可以用 一定的 材料，結構生產(chǎn)是嚴格復雜的，保證了容器的安全生產(chǎn)與安全使用。通過對常溫低壓 熔化槽槽體 焊接工藝評定的研究，發(fā)現(xiàn)壓力容器的制作是一個復雜而又嚴緊的過程，壓力容器的每個部分都需要確定使用的材料與焊接工藝，不可忽視每一個很小的環(huán)節(jié)，否則將會有生命的危險。這樣多種性的操作特點給壓力容器從選材、制造、檢驗到使用、維護以致管理等諸方面造成了復雜性，因此對壓力容器的制造、現(xiàn)場 組焊、檢驗等諸多環(huán)節(jié)提出了越來越高的要求。 關鍵詞：壓力容器結構生產(chǎn) ； 焊接工藝 ； 焊接參數(shù) ； 焊縫質量檢驗 ； 熔化槽槽體 桂 林 航 天 工 業(yè) 學 院 II Pressure vessel manufacturingtechnology research Science Students cheng xing jun Guidance teacher Wei Zhen Abstract Along with the science and technology development, the pressure vessel manufacture level is more and more high,The pressure vessel involves many disciplines, the prehensive nature is very strong, a pressure vessel determines from the parameter to the investment normal use,must can realize through very many links and the correlation department39。s each kind of engineers and technicians39。 joint present paper has summarized the pressure vessel structure standard, Mainly has studied the pressure vessel welding craft and the craft evaluation,In has carried on certain introduction and the author to the Melting groove understood under the premise, has carried on the welding operation code formulation and the welding craft evaluation to the propane storage tank,Consults the data collection after the author, elaborated the pressure vessel position structure and the pressure vessel standard, through the consult welding handbook and the pressure vessel craft handbook, had certain understanding to the pressure vessel welding material and the welding craft,Has pleted the pressure vessel operation code manufacture and the craft evaluation in under teacher39。s vigorously care and counselling,Through to the propane storage tank welding craft evaluation, discovered the pressure vessel the manufacture may use certain new material, the structure production is strict plex, has guaranteed the vessel safety in production and the safety handling Through to the normal temperature low pressure Melting groove welding craft evaluation research, discovered the pressure vessel the manufacture is 桂 林 航 天 工 業(yè) 學 院 III one plex and the close process, pressure vessel each part all needs to determine the use the material and the welding craft, noticeable each very small link, otherwise will be able to have the life that such many kinds of the operating feature for the pressure vessel from the selection, the manufacture, examined to the use, the maintenance the management and so on the various aspects has created the plexity, therefore to the pressure vessel manufacture, the scene group welded, the examination and so on many links set the more and more high request.
