手工鎢極氬弧工藝特點工作原理鎢極氬弧焊是采用鎢棒作為電極，利用氬氣作為保護(hù)氣體進(jìn)行焊接的一種氣體保護(hù)焊方法。通過鎢極與工件之間產(chǎn)生電弧，利用從焊噴嘴中噴出的氬氣流在電弧區(qū)形成嚴(yán)密封閉的氣層，使電極和金屬熔池與空氣隔離，以防止空氣的侵入。同時利用電弧熱來熔化基本金屬和填充焊絲形成熔池。液態(tài)金屬熔池凝固后形成焊縫。由于氬氣是一種惰性氣體，不與金屬起化學(xué)反應(yīng)，所以能充分保護(hù)金屬熔池不被氧化。同時氬氣在高溫時不溶于液態(tài)金屬中，所以焊縫不易生成氣孔。因此，氬氣的保護(hù)作用是有效和可靠的，可以獲得較高質(zhì)量的焊縫。焊接時鎢極不熔化，所以鎢極氬弧焊又稱為非熔化極氬弧焊。根據(jù)所采用的電源種類，鎢極氬弧焊又分為直流、交流和脈沖三種。焊不銹鋼用什么焊條？不銹鋼怎么焊接？焊接技術(shù)焊接是被焊工件的材質(zhì)（同種或異種），通過加熱或加壓或兩者并用，并且用或不用填充材料，使工件的材質(zhì)達(dá)到原子間的結(jié)合而形成長久性連接的工藝過程。那么不銹鋼焊接要點與注意事項有哪些要點呢？焊不銹鋼用什么焊條不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條，這兩類焊條中凡符合國標(biāo)的，均按國標(biāo)GB/T983-2012規(guī)定考核。鉻不銹鋼具有一定的耐蝕。蘇州特種焊絲工廠藥芯焊絲中的藥粉成分一般與焊條藥皮相似。</p><div

補(bǔ)焊要求不高的黃銅鑄件可采用純銅芯焊條，如ECu（T107）。電源采用直流正接，V型坡口角度不應(yīng)小于60°～70°。板厚超過14mm時，焊前焊件表面應(yīng)仔細(xì)清理，***一切會產(chǎn)生氫氣的油類雜質(zhì)。操作時應(yīng)當(dāng)用短弧焊接，焊條不做橫向和前后擺動，只沿焊縫的直線移動。焊接速度要快，不應(yīng)低于～。多層焊時，層與層之間的氧化膜及渣應(yīng)***干凈。黃銅的銅液流動性大，故溶池比較好處于水平位置，若溶池必須傾斜，則傾角不應(yīng)大于15°3．黃銅的手工氬弧焊手工鎢極氬弧焊時，焊絲采用錫黃銅焊絲HSCuZ-1（HS221）、鐵黃銅焊絲HSCuZn-2（HS222）、硅黃銅焊絲HSCuZn-4（HS224）。這些焊絲含鋅較高，焊接時煙霧較大。亦可用青銅焊絲HSCuSi（HS211）、HSCuSn（HS212）。焊接可以用直流正接，也可以用交流。用交流焊接時，鋅的蒸發(fā)比直流正接時輕。通常焊前不用預(yù)熱，只有板厚相差比較大時才預(yù)熱。焊接速度應(yīng)盡可能快。焊件在焊后應(yīng)加熱300~400℃進(jìn)行退火處理，消除焊接應(yīng)力，以防止焊件在使用過程中裂縫。由于鋅的蒸發(fā)破壞氬氣的保護(hù)效果，所以焊接黃銅時應(yīng)選用較大的噴嘴孔徑和氬氣流量。焊前一般不預(yù)熱，只有焊接厚度大于10mm的接頭和焊接邊緣厚度相差比較大的接頭時才需預(yù)熱。</p><p>

焊機(jī)穩(wěn)態(tài)輸出電流和輸出電壓的關(guān)系稱為焊機(jī)的外特性。焊機(jī)的外特性如圖3—12所示。焊機(jī)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(jī)和緩降外特性的焊機(jī)，當(dāng)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(jī)所引起的電流變化要比緩降外特性焊機(jī)所引起的焊接電流變化小得多。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(jī)具有陡降的外特性。圖3—12焊機(jī)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、焊接電纜、面罩及其它防護(hù)用具。(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。山東特種焊絲生產(chǎn)廠</p><p
