1、板厚为6mm的0Cr18Ni9钢板采用焊条电弧焊的焊接工艺 毕业设计论文 题目 板厚为6mm的0Cr18Ni9钢板采用焊条电弧焊 的焊接工艺评定拉伸 专业焊接技术及自动化 班级学号 姓名 指导教师 摘要钢是我们现代社会中不可缺少的一种材料它可以看作一个国家工业化水平的标志钢的产量越高就代表这个国家的工业化水平越高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兴旺国家每年消耗的不锈钢中有70的是不锈钢在我过也到达了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0cr18n
2、i9就是奥氏体不锈钢我做的这个课题就是探讨0cr18ni9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0cr18ni9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0cr18ni9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0cr18ni9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篇论文中我会通过一个焊接性试验来探讨0gr18ni9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0cr18ni9扳水平对接焊接方法就是手工电弧焊针对这
3、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0cr18ni9的各项性能关键词 焊接性能力学性能使用性能焊接工艺 Abstract Steel our modern society is indispensable to a material it can be seen as a sign of the level of industrialized countries The higher the output of steel on behalf of this country the higher the level of industri
