焊機穩(wěn)態(tài)輸出電流和輸出電壓的關(guān)系稱為焊機的外特性。焊機的外特性如圖3—12所示。焊機外特性有三種形式：即下降特性(陡降、緩降)、平特性和上升特性。由于熔滴過渡和熱慣性以及操作等原因，焊接時電弧長度總是在不斷的變化，因而電弧電壓和焊接電流也在不斷地變化。為保證焊接質(zhì)量穩(wěn)定，總希望焊接過程中焊接電流變動越小越好。從圖3—13可以看出，具有陡降外特性的焊機和緩降外特性的焊機，當焊接電流發(fā)生相應(yīng)的變化值△I時，陡降外特性曲線引起的電壓變化值△U2大于緩降外特性曲線引起的電壓變化值△U1。換句話說，對于相同的弧長變化，陡降外特性焊機所引起的電流變化要比緩降外特性焊機所引起的焊接電流變化小得多，蘇州激光焊絲供應(yīng)商。焊條電弧焊過程中，弧長變化是經(jīng)常發(fā)生的，為了保證焊接電流穩(wěn)定，顯然要求焊機具有陡降的外特性。圖3—12焊機外特性曲線1—陡降外特性曲線2—緩降外特性曲線3—上升特性曲線4—乎特性曲線圖3—13兩種不同下降程度的外特性曲線1—緩降外特性曲線2—陡降外特性曲線五、焊條電弧焊輔助設(shè)備和工具焊條電弧焊輔助設(shè)備和工具包括電焊鉗，蘇州激光焊絲供應(yīng)商、焊接電纜、面罩及其它防護用具，蘇州激光焊絲供應(yīng)商。(一)電焊鉗電焊鉗是夾持焊條并傳導(dǎo)焊接電流的操作器具。直至1972年小絲徑焊絲開始發(fā)展才**的擴展了藥芯焊絲使用的領(lǐng)域。蘇州激光焊絲供應(yīng)商</p><div

1、焊接方法板狀仰焊的焊接有2種方法：連弧法及熄弧法。連弧法是通過連續(xù)而有規(guī)則地擺動焊條進行短弧施焊的操作方法；熄弧法是在封底焊時采用電弧燃燒一定時即行熄滅，然后再引燃、再熄滅，從而使熔池金屬迭加成形的方法。這2種方法各有所長。熄弧法可以保證封底焊縫有良好的成形，能有效地控制焊縫下垂、頂面內(nèi)凹，缺點是由于焊接過程處于間斷狀態(tài)，容易出現(xiàn)氣孔、夾渣等缺點。連弧法可以使焊接過程連續(xù)化，能夠有效地保證焊接質(zhì)量，但操作方法不當將會造成焊縫下垂，表面內(nèi)凹。比較2種焊接方法，連弧焊更值得推廣。在一些工業(yè)發(fā)達國家，如德國、美國、日本等，生產(chǎn)中都要求采用這種焊接方法。2試板及工藝要求試板要求試板材質(zhì)為Q235B，規(guī)格為100mm×12mm×300mm。采用E5015（J507）焊條，焊接位置為仰焊，要求單面焊雙面成形。坡口形式如圖1所示。焊接工藝參數(shù)焊接工藝參數(shù)見表1。表1焊接工藝參數(shù)焊條角度施焊過程中焊條與焊接方向的夾角如圖2所示。3、焊接操作要點封底層的焊接對整個試板而言，封底層的焊接是關(guān)鍵，在焊接過程中，焊接熔池金屬的自身重力在電弧作用力和液態(tài)金屬的表面張力作用下處于平衡狀態(tài)。具體操作是地。浙江特種焊絲工廠藥芯焊絲工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護，獲得良好成形。</p><div

黃銅焊接黃銅焊接是修鋪、加工銅材時候必不可少的加工技術(shù)。焊接，也叫作熔接、镕接，是一種常見的以加熱方式接合金屬或其他熱塑性材料如塑料的制造工藝及技術(shù)。下面將介紹黃銅的焊接性和黃銅焊接方法。黃銅焊接性黃銅是銅鋅合金，由于鋅的沸點較低，*為907℃，故焊接過程中極容易蒸發(fā)，這一點成為黃銅焊接的比較大問題。在焊接高溫作用下，焊條電弧焊時鋅的蒸發(fā)量高達40%，鋅的大量蒸發(fā)，導(dǎo)致焊接接頭的力學性能和耐蝕性能下降，還使之對應(yīng)力腐蝕的敏感性增大。蒸發(fā)的鋅在空氣中立即被氧化成氧化鋅，形成白色的煙霧，給操作帶來很大困難，而且影響焊工身體健康，因此，焊接黃銅的場所，應(yīng)加強通風等防護措施。黃銅的焊接性不良，焊接時會產(chǎn)生氣孔、裂紋、鋅的蒸發(fā)和氧化等問題。為了解決這些問題，在焊接時常用含硅的焊絲，因為硅在熔池表面會形成一層致密的氧化硅薄膜，阻礙鋅的蒸發(fā)和氧化，并防止氫的入侵。焊后可經(jīng)470～560℃的退火處理，以消除應(yīng)力防止“自裂”現(xiàn)象。黃銅焊接的方法：氣焊、碳弧焊、焊條電弧焊和氬弧焊。1．黃銅的氣焊（1）焊絲和焊粉：焊絲采用絲221、絲224。這些焊絲中的硅、錫、鐵元素既是脫氧劑，防止焊縫產(chǎn)生氣孔，又能防止和減少鋅的蒸發(fā)和燒損。</p><p> 要做到以下要求：一是為了保證試板坡口兩側(cè)有良好的熔合，采用的焊接電流宜稍大，當用ф，焊接電流以90A為宜；二是要采用短弧施焊，以利于保護熔池，同時利用電弧作用力把熔池鐵液托住，并且把部分熔滴過渡到試件背面（即上面）；三要使后續(xù)熔池覆蓋前一熔池的1/2，并適當提高焊接速度，以減小熔深，減小液態(tài)金屬自身重力，避免焊縫金屬下垂上凹；四是保持正確的運條方式，使焊條與試板左右兩側(cè)呈90o，并與焊接方向呈70o～80o的夾角。施焊時，焊件背面應(yīng)保持2/3弧柱，以利于熔滴過渡和熔池保護。運條時應(yīng)左右輕微擺動。當焊至接近試板中部時，因變形使間隙變窄，此時可不使焊條左右橫向擺動，而沿焊接方向連弧焊接；五是更換焊條接頭要迅速，應(yīng)在接頭部位處于紅熱狀態(tài)下迅速引弧，盡快恢復(fù)焊接狀態(tài)，這樣可使接頭處成形良好，也可減少氣孔、夾渣等缺點。填充層的焊接填充層采用左右擺動運條方式連弧焊接，操作昱應(yīng)注意兩點：一要使焊條與試板在左右方向上處于垂直狀態(tài)，以避免填充層焊縫左右不等厚，影響焊縫成形。為了把握好角度，有的焊工改用雙手握焊鉗施焊，效果不錯；二要將道間熔渣清理干凈，避免出現(xiàn)夾渣。填充層以2層為宜，較薄的焊層。電弧穩(wěn)定劑鈉及鉀可以使電弧保持柔和順暢而且降低飛濺。</p><div

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(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。鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強度、延性、硬度及韌性等。浙江特種焊絲工廠</p><p
