注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號舉例如下：例14、焊條的選用（1）結構鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結構鋼制造的焊接結構，大多要求焊縫金屬與母材等強度，此時可按結構鋼的強度選擇相應強度等級的焊條。選擇時應注意以下兩點：1）鋼材的強度等級是按屈服點劃分的，而結構鋼焊條的強度等級系指其抗拉強度的比較低保證值，兩者是不一致的。通常應選擇抗拉強度保證值與母材相同或稍高的焊條。2）焊縫強度不是比母材高出愈多愈好，而應等于或稍高于母材。如果焊縫強度過高，往往使焊縫的塑性下降，反而有害。當焊接接頭不要求焊縫與其等強度時，可選用抗拉強度較低的焊條。（2）合金結構鋼焊條的選用合金結構鋼焊接時，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強度。但如果母材是耐熱鋼、耐腐蝕鋼時，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時，應根據(jù)母材的化學成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S、P等雜質較高時，很容易在焊縫中形成裂紋。安徽SKD-11焊絲工廠線材表面亦需光滑平順且清潔否則將影響送絲的順暢及焊接電流的傳迅。</p><div

焊接重要的焊接構件及合金鋼焊件，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，后果很嚴重，不但會產(chǎn)生焊接缺點，也會嚴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、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順利進行，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，提高焊縫質量。</p><p> 焊前準備：大直徑厚壁管U形坡口的試件如下圖所示。材料為20鋼，其裝配及定位與第四章水平轉動焊條電弧焊相同。設備：焊條電弧焊的焊機為ZXG-400,埋弧焊焊機為MZ3-500,焊接調速滾輪架一臺，焊接操作架一臺。焊前清理與上述相同，焊劑、焊條須嚴格烘干。焊接參數(shù)焊接參數(shù)見下表，焊接電源極性釆用直流反接。焊接操作：打底層和填充層都采用焊條電弧焊，焊接操作與第四章第四節(jié)的大直徑管水平轉動焊相同。蓋面層采用埋弧焊，焊劑為HJ431，其顆粒度為(14~60目）。采用直流反接。焊接蓋面層時，先預調節(jié)焊接參數(shù)，調節(jié)焊接機頭使焊嘴距離焊件20~30mm，下圖中的偏移量B為20~30mm，并使焊絲對準坡口的中心線，開啟焊劑漏斗，使焊劑堆在待焊區(qū)，由于管子表面曲率較大，焊劑容易散失，為在焊接過程中更好地保護熔池，可在焊接區(qū)的前方加一如圖所示擋板或采取其它防止焊劑散失的措施。按下“啟動”按鈕，進行焊接，并耳聽和觀察焊接過程，注意焊機的電流表和電壓表及調速滾輪的轉速表的指示，隨時進行調節(jié)，以保證焊接過程的穩(wěn)定。在焊完一周后須重疊一段焊縫，***按“停止”按鈕，熄弧后關閉焊劑漏斗。焊后清理與檢驗：用錘子、鋼絲刷***焊渣，并對收弧處進行修磨。藥芯焊絲的制造過程控制非常嚴謹，由于熔填金屬來自鋼片皮材及焊劑所含的成份。</p><div
