1、河海大学常州校区 毕业设计（论文）焊条电弧焊06Cr19Ni10低温压力容器的焊接工艺评定年级专业 2010级焊接技术及工程 学生姓名 指导教师 评 卷 人 教学地点 河海大学常州校区 2012 年 3 月 28 日摘 要不锈钢是钢中非常重要的一种，由于不锈钢具有特殊的使用性能和力学性能，在现在的各行各业中已经被越来越多的使用。在不锈钢中奥氏体不锈钢又是其中非常重要的一种，在发达国家每年消耗的不锈钢中有70的是不锈钢，在我过也达到了65左右。因此开发和使用好奥氏体不锈钢对我过的工业话来说已经越来越重要了。06Cr19Ni10就是奥氏体不锈钢，我做的这个课题就是探讨06Cr19Ni10在低温贮罐制造中的性能。低温贮罐是用来储存液N液Ar液态的CO2等低温液体的容器，液态介质的特殊性能就决定了制造材料需要特殊性能，而奥氏体不锈钢06Cr19Ni10就具有这样的性能。低温贮罐在现在的生活、生产中使用已经越来越广泛，因此对06Cr19Ni10的探讨就显得越来越重要。在这篇论文中我会着重为大家阐述06Cr19Ni10在低温压力容器制造中的焊接性能，力学性能，使用性能和焊接工艺。在这论文中我会通过

2、一个焊接性试验来探讨06Cr19Ni10在低温压力容器中的各项性能。我的这个试验就是规格为6150300mm的两块06Cr19Ni10扳水平对接焊接方法就是手工电弧焊。针对这个试验做出完整的焊接工艺评定，并且根据评定要求对式样做相应的无损检验和力学性能的检验，从而来判定06Cr19Ni10的各项性能。其中力学性能测试包括试样的拉伸，弯曲，冲击等，而无损检测则采取射线检测和渗透检测相结合的方法。关键词: 焊接性能；力学性能；使用性能；焊接工艺AbstractStainless steel is a very important one, because of the use of stainless steel with special performance and mechanical properties, in all walks of life in the present have been increasingly used.

In this paper I will focus on as we set out in the cold 06Cr19Ni10 pressure vessel manufacture of welding performance, mechanical properties, the use of performance and welding technology.In this paper I will pass a welding test to explore 06Cr19Ni10 in low-temperature pressure vessel in the performance. This is my test specifications for
