大連恒力石化裝置中工藝管道為大口徑厚壁管，焊接材質(zhì)為奧氏體不銹鋼TP347材質(zhì)，江西日亞焊條工廠，比較高設(shè)計(jì)壓力，試驗(yàn)壓力，工作溫度426℃。為了保證不銹鋼厚壁管TP347管道焊接質(zhì)量及安全運(yùn)行，采用焊接新設(shè)備、工藝管道固定口全位置機(jī)動(dòng)焊不銹鋼實(shí)芯焊絲脈沖MIG焊接技術(shù)，根據(jù)奧氏體不銹鋼脈沖MIG焊接工藝性能進(jìn)行了分析，制定了合理的焊接工藝和技術(shù)措施，焊前對(duì)參加奧氏體不銹鋼超高壓厚壁管道的焊接作業(yè)人員進(jìn)行專項(xiàng)焊接技能培訓(xùn)，確保了工程的焊接質(zhì)量及工效。，導(dǎo)熱系數(shù)小，熱膨脹系數(shù)大，焊接時(shí)容易產(chǎn)生較大的焊接應(yīng)力和變形。由于奧氏體不銹鋼含Cr、Ni較高，因此在氧化性、中性以及弱還原性介質(zhì)中均具有良好的耐蝕性。其塑韌性優(yōu)良，冷熱加工性能具佳，因而***應(yīng)用于石油、化工等工業(yè)領(lǐng)域。奧氏體不銹鋼TP347管道材料化學(xué)成分和力學(xué)性能分析如表1、表2所示。表1材料的化學(xué)成分（質(zhì)量分?jǐn)?shù)）（%）?表2材料的力學(xué)性能?奧氏體不銹鋼TP347耐腐蝕性強(qiáng)，江西日亞焊條工廠，江西日亞焊條工廠、焊接性良好，采用傳統(tǒng)的SMAW焊接方法，能獲得良好的焊接接頭和較好的焊接質(zhì)量，但是施工效率較低，而且成本高，焊工勞動(dòng)強(qiáng)度大，焊接質(zhì)量不穩(wěn)定。目前化工行業(yè)各單位主要采用GMAW藥芯焊絲焊接來(lái)替代SMAW焊接方法。在焊接結(jié)構(gòu)剛性大、接頭應(yīng)力高、焊縫易產(chǎn)生裂紋的不利情況下，應(yīng)考慮選用比母材強(qiáng)度低的焊條。江西日亞焊條工廠</p><div

雖然可以保證焊接質(zhì)量，提升施工效率，降低焊工的勞動(dòng)強(qiáng)度，但是焊接成本較高，難以達(dá)到降本增效的目的。而采用管道全位置機(jī)動(dòng)焊不銹鋼實(shí)芯焊絲脈沖MIG焊，則取得了良好的焊接接頭，施工效率高，焊接質(zhì)量好。2.焊前準(zhǔn)備（1）焊接設(shè)備選擇目前國(guó)內(nèi)管道固定口全位置機(jī)動(dòng)焊焊接設(shè)備有各種機(jī)型及不同規(guī)格，通過(guò)***的調(diào)研和分析，選擇了昆山安意源產(chǎn)CH-50，具有斬波器電路，抵抗輸入電壓波動(dòng)能力極強(qiáng)。1096巴馬小型豬頭頸部動(dòng)脈的磁共振血管成像研究李帥，王立鵬，景國(guó)東，王鐵功，陳錄廣，弓靜，彭雯佳，陸建平（2）焊接材料選擇焊接材料選擇了大西洋牌號(hào)CHW-347R不銹鋼實(shí)芯焊絲，焊絲直徑，焊材的化學(xué)成分和力學(xué)性能如表3、表4所示。（3）坡口加工奧氏體不銹鋼切割及坡口應(yīng)采用機(jī)械加工，必須使用不銹鋼**的砂輪片或鋼絲輪將坡口及其兩側(cè)各50mm范圍內(nèi)的污物清理干凈。填充層焊接應(yīng)將GTAW打底層表面及其坡口內(nèi)的污物和氧化層清理干凈。管道固定口全位置機(jī)動(dòng)焊坡口角度尤為重要，對(duì)熱焊層的焊接質(zhì)量有一定影響。由于受焊噴嘴的限制，如果坡口角度過(guò)小，導(dǎo)電嘴離熔池的焊絲干伸長(zhǎng)過(guò)長(zhǎng)，容易造成層間熔合不良。對(duì)于管壁厚度≤40mm的焊件，選擇單面V形坡口。蘇州沒(méi)有硬度鑄鐵焊條廠家焊芯成分直接影響著焊縫金屬的成分和性能，所以焊芯中的有害元素要盡量少。</p><div

高氮奧氏體不銹鋼是含氮量在，用氮元素代替昂貴的鎳元素作為奧氏體化元素的新型鋼種[1]，由于其特有的成本優(yōu)勢(shì)，近些年許多學(xué)者對(duì)高氮鋼研制及應(yīng)用進(jìn)行了進(jìn)一步深入研究，發(fā)現(xiàn)其具有良好的力學(xué)性能和耐腐蝕性能，在生物醫(yī)藥、海洋平臺(tái)、大型設(shè)備等各個(gè)領(lǐng)域得到推廣和應(yīng)用[2]。尤其值得一提的是，由于這種材料在高應(yīng)變沖擊下強(qiáng)度及韌性較常規(guī)材料有明顯提高，這為重載及承受沖擊載荷的設(shè)備開(kāi)發(fā)提供了新型材料。高氮鋼的比強(qiáng)度、比剛度隨著含氮量的提高也有明顯提升，高的比強(qiáng)度和比剛度能明顯減輕結(jié)構(gòu)重量，因此市場(chǎng)對(duì)高含氮量的材料需求更為迫切，目前含氮量在。高氮鋼的實(shí)際應(yīng)用在很大程度上受限于它的焊接性能，在焊接過(guò)程中，氮元素易在熔池中聚集成逸出，導(dǎo)致焊接接頭部位含氮量***降低，力學(xué)性能急劇下降[3]。如何降低焊接過(guò)程中的氮損失，或者在焊接過(guò)程中通過(guò)人為干預(yù)，向熔池中增氮，成為解決高氮鋼焊接的技術(shù)關(guān)鍵，這對(duì)高氮鋼的焊接材料提出了很高的要求。目前的高氮焊絲開(kāi)發(fā)，一般都是基于成分匹配及焊接接頭組.織匹配原則開(kāi)發(fā)的[4]，因而需要深入考察焊絲的焊接工藝性。若焊接工藝性不好，一方面氮的聚集和逸出容易導(dǎo)致氮?dú)饪缀瓦^(guò)大的焊接飛濺。</p><p>
