引弧不好，電弧不穩(wěn)，熔池淺。導(dǎo)電嘴-母材間距離過短時(shí)：噴嘴容易被飛濺物堵塞，看不清焊接線，熔深變深。6.焊角度：二氧化碳?xì)怏w保護(hù)焊一般采用向前行進(jìn)法，這樣便于觀察焊接，焊縫形狀，氣體保護(hù)效果等。7.焊移動(dòng)和作業(yè)姿勢：焊由送絲軟管，氣管，控制電纜等構(gòu)成，為不影響焊接效果，應(yīng)采用保證焊彎曲不要過大，焊平衡的作業(yè)姿勢。操作者姿勢及焊操作不好時(shí)，均得不到均勻的焊縫，因此，改變姿勢，計(jì)算電壓進(jìn)行聯(lián)系，以求得到均勻的焊縫。8.收弧處理：在弧坑部開閉焊開關(guān)2~3次，使電弧重復(fù)閃滅進(jìn)行處理。在焊縫還是塊狀時(shí)，每隔，江蘇高溫焊條焊絲銷售廠，開3次即可充分埋好火口。9.焊縫連接方法：在火口前方引弧后，等電弧穩(wěn)定下來再返回火口部（接點(diǎn)）進(jìn)行焊接。五、日常檢修項(xiàng)目焊：清，江蘇高溫焊條焊絲銷售廠.除噴嘴，導(dǎo)電嘴，連接桿等部件上的飛濺物。導(dǎo)電嘴的檢查-焊絲是否吻合，孔徑是否合適，連接是否牢固，導(dǎo)電嘴是否在噴嘴的中間位置。檢查送絲機(jī)的零件是否有損壞或松動(dòng)，并及時(shí)***送絲部位的灰塵及贓物。檢查氣路是否有漏氣現(xiàn)象。檢查焊及焊接一體線是否有破損，如有銅線破損應(yīng)立即用絕緣膠布包好。六、氣保焊機(jī)參數(shù)調(diào)整方法1，江蘇高溫焊條焊絲銷售廠.比較好焊接規(guī)范（電流，電壓參數(shù)）的主要特征焊縫成型好。焊接過程穩(wěn)定，飛濺小。?鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強(qiáng)度、延性、硬度及韌性等。江蘇高溫焊條焊絲銷售廠</p><div

盡量選擇小電流焊接，因?yàn)樵陔娏魈髸r(shí)，易造成熔池翻滾，不僅飛濺大，成形也很差。6、焊接速度：對焊縫內(nèi)部與外觀的質(zhì)量都有重要影響。焊速過快會(huì)使氣體保護(hù)不好，出現(xiàn)氣孔等缺點(diǎn)，同時(shí)焊縫的冷卻速度相應(yīng)提高，因而降低了焊縫金屬的塑性的韌性。焊速過慢時(shí)，熔池變大，焊縫變寬，易因過熱造成焊縫金屬組.織粗大或燒穿。7、噴嘴與工件的角度：當(dāng)噴嘴與工件垂直時(shí)，飛濺會(huì)很大，電弧不穩(wěn)。為避免這種情況的出現(xiàn)，可將噴嘴后傾10-15度（焊接位置不同，焊角度也不同），即可保證焊縫成形良好，焊接過程穩(wěn)定。8、運(yùn)條方法：1.直線法，直線往復(fù)法。（適合小而窄的焊縫）。2.鋸齒形（適合寬焊縫），操作要點(diǎn)：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運(yùn)條法（同鋸齒形）。以下幾種不宜掌握，知道就可以，三角形（斜三角，正三角），圓圖形（斜圓圖，正圓圖），八字形。七、焊接手法及焊接缺點(diǎn)產(chǎn)生的原因1.平焊（以右手向左焊，焊縫成形好，容易觀察熔池成形情況。角度大約45度;以右手向右焊，焊縫成形差）。</p><p> 具有工藝性能良好、操作方便、焊接質(zhì)量穩(wěn)定的特點(diǎn)。在不易進(jìn)行背面充氬保護(hù)的管道焊接作業(yè)及高空作業(yè)時(shí)其優(yōu)點(diǎn)更為突出，值得在火力發(fā)電廠安裝工程中推廣應(yīng)用。1、焊接材料與工藝本次試驗(yàn)中母材采用1Cr18Ni9奧氏體不銹鋼，規(guī)格為Ф42mm×5mm，化學(xué)成分及力學(xué)性能見表1、表2。焊絲為昆山京群焊材科技有限公司生產(chǎn)的GTS-F308L藥芯焊絲，符合AWS-95R308LT1-5及GB/T17853-99R308LT1-5標(biāo)準(zhǔn)。焊絲規(guī)格為Ф×915mm，藥芯焊絲熔敷金屬的化學(xué)成分見表3。坡口尺寸的選擇坡口型式、對口參數(shù)及焊道設(shè)計(jì)見附圖。由于奧氏體不銹鋼的導(dǎo)熱系數(shù)小而線膨脹系數(shù)大，焊接時(shí)變形大。如果在焊接時(shí)選用的坡口較大，則將會(huì)增多填充金屬，增加焊的擺動(dòng)距離，降低焊接速度，加大了變形量，增加了焊縫在高溫段的停留時(shí)間，增加了產(chǎn)生晶間腐蝕及熱裂紋的可能性，所以在保證焊縫質(zhì)量及焊工易操作的前提下，應(yīng)適當(dāng)減少坡口尺寸。經(jīng)過反復(fù)實(shí)踐，將坡口尺寸選擇為55°±5°。對口間隙也適當(dāng)增大，有利于熔渣流到焊縫根部以保護(hù)根部焊縫不受氧化。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。藥芯焊絲的分類及特點(diǎn) 藥芯焊絲是將藥粉包在薄鋼帶內(nèi)卷成不同的截面形狀經(jīng)軋拔加工制成的焊絲。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇高溫焊條焊絲銷售廠,焊條焊絲"

高強(qiáng)鋼用實(shí)芯焊絲與藥芯焊絲熔敷金屬工藝性試驗(yàn)對比研究通過具體的焊接試驗(yàn)，分析總結(jié)出700MPa、900MPa不同級別實(shí)芯焊絲與藥芯焊絲各自的焊接工藝特點(diǎn)，為公司焊材的選用提供技術(shù)支持。關(guān)鍵詞：調(diào)質(zhì)鋼；焊接熱輸入；實(shí)芯焊絲；藥芯焊絲一、概述隨著工程機(jī)械產(chǎn)品輕量化、大型化的發(fā)展，低合金高強(qiáng)鋼的應(yīng)用領(lǐng)域越來越多。我公司在履帶式起重機(jī)、全地面起重機(jī)、礦用挖掘機(jī)等工程機(jī)械中已大量使用低合金高強(qiáng)鋼。由于低合金高強(qiáng)鋼的焊接工藝在以前沒有相關(guān)的資料積累，如何在現(xiàn)有的條件下，解決低合金高強(qiáng)鋼的焊接問題，成為當(dāng)前**首要的攻關(guān)內(nèi)容。因此，本文通過對高強(qiáng)鋼用實(shí)芯焊絲與藥芯焊絲進(jìn)行焊接試驗(yàn)對比研究，為公司產(chǎn)品制造提供技術(shù)支持，同時(shí)降低生產(chǎn)成本。二、焊接試驗(yàn)針對高強(qiáng)鋼母材類型，選擇與之匹配的實(shí)芯焊絲和藥芯焊絲進(jìn)行對比試驗(yàn)。焊接試板坡口形式如附圖所示。試板坡口形式（1）焊接試板某鋼廠生產(chǎn)的Q690E調(diào)質(zhì)鋼，板厚20mm。其化學(xué)成分及力學(xué)性能如表1、表2所示。（2）焊接材料的選擇與試驗(yàn)實(shí)芯焊絲：選用奧林康（OERLIKON）公司的Mn3Ni1CrMo，φ（ESAB）公司的okAristRod69，φ；藥芯焊絲：選用斯泰因（STEIN-MEGAFIL）公司的MF742B，φ742M，φ。。用薄鋼帶卷成圓形或異形鋼管，內(nèi)填一定成分的藥粉，經(jīng)拉制成的有縫藥芯焊絲。江蘇高溫焊條焊絲銷售廠</p><p

2）焊絲端部應(yīng)始終處于氬氣保護(hù)之中，防止合金元素的氧化、燒損。為使熔渣盡快浮出，根據(jù)情況可用焊絲對高溫熔池進(jìn)行適當(dāng)攪拌，不宜依靠降低焊速來促使熔渣浮出。焊后在焊縫表面形成的熔渣薄而脆，高溫時(shí)極易自行脫落，故焊接時(shí)應(yīng)戴好防護(hù)眼鏡，防止灼傷眼睛。（3）要獲得美觀均勻的焊縫很大程度上取決于正確掌握熔池的溫度。當(dāng)發(fā)現(xiàn)熔池增大出現(xiàn)下凹，說明熔池溫度過高，這時(shí)應(yīng)迅速減少焊與工件的夾角，并加快焊接速度。當(dāng)熔池小焊縫窄而高時(shí)，說明熔池溫度低，這時(shí)應(yīng)增大焊與工件的夾角，減慢焊接速度，減少焊絲添加量。（4）1Cr18Ni9不銹鋼在450~800℃溫度區(qū)加熱，常發(fā)生沿晶界的腐蝕破壞，稱為晶間腐蝕。為防止打底層焊縫金屬產(chǎn)生晶間腐蝕，應(yīng)以快焊快冷為原則，盡量采用小的焊接熱輸入、快速焊、短弧焊、小幅擺動(dòng)。（5）焊接時(shí)焊要等速移動(dòng)，禁止抖動(dòng)。焊絲與工件表面的夾角在25°左右，既可保證藥芯焊絲冶金反應(yīng)的充分性，又可避免填充金屬的過熱。鎢極端頭與熔池表面的距離應(yīng)保持在3mm左右，使操作者的視線寬廣，送絲方便，避免焊縫夾鎢。（6）為避免在接頭收弧時(shí)產(chǎn)生縮孔，應(yīng)盡量采用短弧焊，焊擺動(dòng)要均勻，要保證藥芯焊絲的焊接冶金反應(yīng)過程和脫渣過程充分進(jìn)行。江蘇高溫焊條焊絲銷售廠</p><p
