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)，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，江蘇卡斯特林焊條批發(fā)。，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)、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，江蘇卡斯特林焊條批發(fā)，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。如果用于埋弧自動(dòng)焊，江蘇卡斯特林焊條批發(fā)、電渣焊、氣體保護(hù)焊、氣焊等熔焊方法作填充金屬時(shí)，則稱為焊絲。江蘇卡斯特林焊條批發(fā)</p><div

附圖坡口型式與焊道設(shè)計(jì)焊接位置為45°斜焊（6G）。打底層和該面層全部采用藥芯焊絲進(jìn)行焊接。層間溫度的控制奧氏體不銹鋼焊接中，控制層間溫度對(duì)避免產(chǎn)生晶問(wèn)腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時(shí)應(yīng)盡量選用小線能量快速焊。層間溫度應(yīng)控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見(jiàn)表4所示。2、焊縫外觀檢驗(yàn)及性能試驗(yàn)焊縫外觀成形良好，尤其是焊縫背面成形美觀，無(wú)焊瘤、未熔合、未焊透等缺點(diǎn)。射線檢測(cè)按照J(rèn)B/T4730《承壓設(shè)備無(wú)損檢測(cè)》標(biāo)準(zhǔn)進(jìn)行，II級(jí)及以上為合格，經(jīng)評(píng)定為合格。力學(xué)性能試驗(yàn)按GB/T228和GB/T2653規(guī)定的試驗(yàn)方法，對(duì)焊接接頭試樣進(jìn)行了拉伸試驗(yàn)和彎曲試驗(yàn)，拉伸實(shí)驗(yàn)結(jié)果如表5所示，彎曲試驗(yàn)結(jié)果如表6所示。實(shí)驗(yàn)結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進(jìn)行保護(hù)，所以根部焊接時(shí)與實(shí)芯焊絲焊接的操作方法、電弧擺動(dòng)頻率、填絲量有較大區(qū)別。（1）在焊接過(guò)程中，焊要做圓弧形擺動(dòng),其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時(shí)也可增加母材坡口兩側(cè)的熱輸入量。江蘇卡斯特林焊條批發(fā)焊接時(shí)，焊芯是傳導(dǎo)焊接電流，產(chǎn)生電弧把電能轉(zhuǎn)換成熱能。</p><div

往往增大焊接電流和氬氣流量對(duì)熔渣形成較大的吹力，其實(shí)這是一種錯(cuò)誤的做法。只要操作手法正確，正常的焊接電流（70~140A）和每分鐘9~12L的氬氣流量一樣能分清熔渣和熔池金屬。隨著我國(guó)生活水平和醫(yī)療水平的提高，老年人的平均壽命不斷延長(zhǎng)，相對(duì)的老年人的可勞動(dòng)年齡也不斷延長(zhǎng)。老年人豐富的勞動(dòng)經(jīng)驗(yàn)和較于年輕人更敬業(yè)的勞動(dòng)精神是其具有的****的競(jìng)爭(zhēng)力。創(chuàng)造有利于老年人力資源開(kāi)發(fā)的政策環(huán)境，充分開(kāi)發(fā)老年人力資源，大力開(kāi)展老年教育，不斷更新老年人的知識(shí)，鼓勵(lì)活到老學(xué)到老，使老年人適應(yīng)新科技的不斷創(chuàng)新，從而為其創(chuàng)造參與社會(huì)勞動(dòng)的有利條件。并且在老齡人工作經(jīng)驗(yàn)和技能指導(dǎo)優(yōu)勢(shì)的工作領(lǐng)域上，適當(dāng)延長(zhǎng)老齡人的退休年齡增加勞動(dòng)力的供給，充分發(fā)揮利用老年勞動(dòng)力資源，彌補(bǔ)我國(guó)勞動(dòng)力數(shù)量的減少所帶來(lái)的劣勢(shì)。（2）焊角度國(guó)產(chǎn)焊絲在焊接時(shí)焊比較好對(duì)著熔池，與焊接方向成70°~80°，這樣電弧正對(duì)著熔池，依靠電弧較小的吹力就能保證熔渣和鐵液能夠分開(kāi)，同時(shí)又避免了熔渣過(guò)快凝固造成夾渣缺點(diǎn)。進(jìn)口焊絲涂層較薄，熔渣和鐵液流動(dòng)性也較好，焊角度還按照一般氬弧焊的角度焊接即可。（3）送絲方法國(guó)產(chǎn)焊絲要斷續(xù)的快速送入和離開(kāi)熔池，一次要少送點(diǎn)焊絲。酸性焊條焊接工藝性好，電弧穩(wěn)定，可交、直流兩用，飛濺小、熔渣流動(dòng)性和脫渣性好。</p><div
