2021年高压储罐焊接基础工艺设计.doc

毕业设计（论文）汉字摘要
伴随制造业不停发展，锅炉和压力容器在各行各业中被广泛使用，而且因其在生产过程中发挥着越来越关键作用，使用量也正在逐年攀升。
相比于传统压力容器制造方法，经过焊接手段生产压力容器正因为其高生产效率、低生产成本逐步成为压力容器制造业中主流。但焊接生产过程中有较多质控点较难把握，影响焊缝质量原因较多，造成所焊接产品一次合格率较难有深入提升。
产品制作工艺说明书中，简明分析了储气罐组成；依据材料特点和产品结构尺寸制作出适合本产品工艺步骤；具体叙述储气罐加工、装配、焊接工艺。同时对储气罐制作中轻易出现质量问题进行了分析说明，提出了对应处理方法。焊接方法选手工电弧焊和埋弧焊；焊接材料选择焊条J857、焊丝H10MnSi和焊剂HJ350。

毕业设计（论文）外文摘要
TITLE：BOILER AND PRESSURE VESSEL WELDING METHOD COMMONLY USED TECHNOLOGICAL PARAMETERS OF CHOICE
ABSTRACT：WITH THE CONTINUOUS DEVELOPMENT OF MANUFACTURING INDUSTRY, BOILER AND PRESSURE VESSEL IN ALL WALKS OF LIFE IS WIDELY USED, AND BECAUSE OF ITS PRODUCTION PROCESS IN A MORE AND MORE IMPORTANT ROLE IN, USAGE IS ALSO UP YEAR BY YEAR.
Compared with the traditional pressure vessel manufacture method and by means of welding production of pressure vessels because of its high production efficiency and lower cost of production gradually become the mainstream of the pressure vessel manufacturing industry. But in the process of welding production more qc point is difficult, the influence factors on the quality of the welding seam more, lead to the welding products a qualified rate more difficult to have the further promotion.
Product manufacturing process instructions, a brief analysis of the composition of the gas tank; the characteristics of the material and product structure size to produce products for the process; detail tank fabrication, assembly, welding. At the same time prone to gas tank production quality issues analysis shows, the corresponding measures to resolve. Welding and submerged arc welding players work; welding electrode material selection J857, wire H10MnSi and flux HJ350.
Keywords： High pressure tank、Welding、Design of technology
