焊接重要的焊接構(gòu)件及合金鋼焊件，為了防止氫致裂紋的產(chǎn)生，提高焊縫金屬和熱影響區(qū)的韌性，要選用低氫堿性焊條施焊。使用堿性低氫焊條**重要一環(huán)，是焊條的烘干，必須按照烘干要求進(jìn)行，一般焊前烘干工藝要求為350°×1小時，雨季或潮濕天氣可提高到400°×1小時。烘干不好，后果很嚴(yán)重，不但會產(chǎn)生焊接缺點，也會嚴(yán)重影響焊接工藝性能，千萬不要大意！其次，焊件焊接處要清理干凈，徹底***油污、銹跡、水分、雜質(zhì)、臟東西，合理的焊接工藝這一點都寫得很清楚?！锊僮饕c堿性低氫焊條的操作，主要是采用短弧操作，電弧盡量壓短。焊接時，手把要穩(wěn)，電弧越短越好。運條時，焊條傾角與焊縫前進(jìn)方向成85°-90°，與左右保持垂直，如果焊條傾角過大或左右不正，即使是壓低了電弧，也不是真正的短弧。短弧焊的目的是更好的應(yīng)用渣氣聯(lián)合保護功能，保護熔池不受空氣侵襲，保護熔池焊接冶金反應(yīng)順利進(jìn)行，減少焊接缺點的產(chǎn)生。多層焊時，每層焊肉要薄些，以利于熔池中氣體逸出，熔渣容易浮出，出現(xiàn)缺點也容易清理。多層焊，每層焊縫方向相反，以利于整體焊縫熱量均勻。操作手法采用畫圓圈式的橫向擺動，熔池冷卻速度變慢，利于氣體逸出，避免產(chǎn)生氣孔，提高焊縫質(zhì)量。南京SKD-11焊絲工廠二氧化碳?xì)怏w保護電弧焊（簡稱CO2焊）的保護氣體是二氧化碳（有時采用CO2+O2的混合氣體）。</p><div

電弧周圍形成多種有害氣體，其中主要有臭氧、氮氧化物、一氧化碳和氟化氫等。臭氧是一種刺激性氣體，呈淡藍(lán)色。濃度較高時，發(fā)出腥臭味；高濃度臭氧還略帶酸味。臭氧對人體的主要危害是對呼吸道及肺有強烈刺激作用。往往引起咳嗽、胸悶、食欲不振、疲勞無力、頭暈、全身疼痛等，嚴(yán)重時還會引起***和肺水腫等。氮氧化物是刺激性氣體。二氧化氮呈紅褐色，具有特殊臭味。氮氧化物對人體的危害主要是對肺組.織的刺激作用。其被吸人呼吸道后，在肺泡內(nèi)逐漸與水作用形成硝酸和亞硝酸，對肺組.織產(chǎn)生強烈刺激和腐蝕作用，引起中毒。慢性中毒的主要癥狀是神經(jīng)衰弱，如***、***、食欲不振、體重下降。濃度高的氮氧化物能引起急性中毒，其中毒輕者，*發(fā)生急性***；重度中毒時，引發(fā)咳嗽激烈、呼吸困難、虛脫、全身軟弱無力等癥狀。氮氧化物對人體的作用也是可逆的，隨著脫離作業(yè)時間的增長，其不良影響逐漸減少或消除。在鎢極氬弧焊時，如果不采取通風(fēng)措施，其濃度往往超過衛(wèi)生標(biāo)準(zhǔn)十幾倍，甚至幾十倍。我國規(guī)定的氮氧化物(換算成二氧化氮)的衛(wèi)生標(biāo)準(zhǔn)為5mg／m3。在焊接過程中，通常臭氧和氮氧化物同時存在，因此它們的毒性更大。一般情況下。</p><p> 分別是焊條的送進(jìn)運動、焊條的橫向擺動運動和焊條的沿焊縫移動運動，詳見圖3—16。焊條的三個基本運動1—焊條送進(jìn)2—焊條擺動3—沿焊縫移動(1)焊條的送進(jìn)運動。主要是用來維持所要求的電弧長度。由于電弧的熱量熔化了焊條端部，電弧逐漸變長，有熄弧的傾向。要保持電弧繼續(xù)燃燒，必須將焊條向熔池送進(jìn)，直至整根焊條焊完為止。為保證一定的電弧長度，焊條的送進(jìn)速度應(yīng)與焊條的熔化速度相等，否則會引起電弧長度的變化，影響焊縫的熔寬和熔深。(2)焊條的擺動和沿焊縫移動。這兩個動作是緊密相聯(lián)的，而且變化較多、較難掌握。通過兩者的聯(lián)合動作可獲得一定寬度、高度和一定熔深的焊縫。所謂焊接速度即單位時間內(nèi)完成的焊縫長度。如圖3—17，表示焊接速度對焊縫成形的影響。焊接速度太慢，會焊成寬而局部隆起的焊縫；太快，會焊成斷續(xù)細(xì)長的焊縫；焊接速度適中時，才能焊成表面平整，焊波細(xì)致而均勻的焊縫。焊接速度對焊縫成形的影響(3)運條手法。為了控制熔池溫度，使焊縫具有一定的寬度和高度，在生產(chǎn)中經(jīng)常采用下面幾種運條手法。1)直線形運條法。采用直線形運條法焊接時，應(yīng)保持一定的弧長，焊條不擺動并沿焊接方向移動。由于此時焊條不作橫向擺動，所以熔深較大。藥芯焊絲可用于碳鋼，低合金高張力鋼，**度淬火回火鋼，不銹鋼以及硬面耐磨鋼材等的焊接。</p><div
