【正文】 畢 業(yè) 設(shè) 計(jì)（論文）、 題 目 板厚為6mm的0Cr18Ni9鋼板采用焊條電弧焊 的焊接工藝評(píng)定（拉伸） 摘 要鋼是我們現(xiàn)代社會(huì)中不可缺少的一種材料，它可以看作一個(gè)國(guó)家工業(yè)化水平的標(biāo)志。鋼的產(chǎn)量越高就代表這個(gè)國(guó)家的工業(yè)化水平越高。不銹鋼是鋼中非常重要的一種，由于不銹鋼具有特殊的使用性能和力學(xué)性能，在現(xiàn)在的各行各業(yè)中已經(jīng)被越來(lái)越多的使用。在不銹鋼中奧氏體不銹鋼又是其中非常重要的一種，在發(fā)達(dá)國(guó)家每年消耗的不銹鋼中有70％的是不銹鋼，在我過(guò)也達(dá)到了65％左右。因此開發(fā)和使用好奧氏體不銹鋼對(duì)我過(guò)的工業(yè)話來(lái)說(shuō)已經(jīng)越來(lái)越重要了。0cr18ni9就是奧氏體不銹鋼，我做的這個(gè)課題就是探討0cr18ni9在低溫貯罐制造中的性能。低溫貯罐是用來(lái)儲(chǔ)存液N液Ar液態(tài)的CO2等低溫液體的容器，液態(tài)介質(zhì)的特殊性能就決定了制造材料需要特殊性能，而奧氏體不銹鋼0cr18ni9就具有這樣的性能。低溫貯罐在現(xiàn)在的生活、生產(chǎn)中使用已經(jīng)越來(lái)越廣泛，因此對(duì)0cr18ni9的探討就顯得越來(lái)越重要。在這篇論文中我會(huì)著重為大家闡述0cr18ni9在低溫壓力容器制造中的焊接性能，力學(xué)性能，使用性能和焊接工藝。在這篇論文中我會(huì)通過(guò)一個(gè)焊接性試驗(yàn)來(lái)探討0gr18ni9在低溫壓力容器中的各項(xiàng)性能。我的這個(gè)試驗(yàn)就是規(guī)格為6150300mm的兩塊0cr18ni9扳水平對(duì)接焊接方法就是手工電弧焊。針對(duì)這個(gè)試驗(yàn)做出完整的焊接工藝評(píng)定，并且根據(jù)評(píng)定要求對(duì)式樣做相應(yīng)的無(wú)損檢驗(yàn)和力學(xué)性能的檢驗(yàn)，從而來(lái)判定0cr18ni9的各項(xiàng)性能。關(guān)鍵詞: 焊接性能 力學(xué)性能 使用性能 焊接工藝AbstractSteel our modern society is indispensable to a material, it can be seen as a sign of the level of industrialized countries.

Stainless 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. Austenitic stainless steel in the stainless steel is a very important one, in the developed world consumption of stainless steel annually in 70% of the stainless steel is, I have also reached about 65 percent.
