使氣孔消除，并且不會留引弧傷痕。為了保證焊縫起點處能夠焊透，焊條可作適當?shù)臋M向擺動，并在坡口根部兩側(cè)稍加停頓，以形成一定大小的熔池。引弧點的選擇引弧對焊接質(zhì)量有一定的影響，經(jīng)常因為引弧不好而造成始焊的缺點。綜上所述，在引弧時應(yīng)做到以下幾點：(1)工件坡口處無油污、銹斑，以免影響導電能力和防止熔池產(chǎn)生氧化物。(2)在接觸時，焊條提起時間要適當。太快，氣體未電離，電弧可能熄滅；太慢，則使焊條和工件粘合在一起，無法引燃電弧。(3)焊條的端部要有裸露部分，福建特種焊絲工廠，以便引弧。若焊條端部裸露不均，則應(yīng)在使用前用銼刀加工，防止在引弧時，福建特種焊絲工廠，碰擊過猛使藥皮成塊脫落，引起電弧偏吹和引弧瞬間保護不良。(4)引弧位置應(yīng)選擇適當，開始引弧或因焊接中斷重新引弧，一般均應(yīng)在離始焊點后面10～20mm處引弧，然后移至始焊點，福建特種焊絲工廠，待熔池熔透再繼續(xù)移動焊條，以消除可能產(chǎn)生的引弧缺點。(二)運條電弧引燃后，就開始正常的焊接過程。為獲得良好的焊，縫成形，焊條得不斷地運動。焊條的運動稱為運條。運條是電焊工操作技術(shù)水平的具體表現(xiàn)。焊縫質(zhì)量的優(yōu)劣、焊縫成形的好壞，主要由運條來決定。運條由三個基本運動合成。?焊絲的表面不涂防氧化作用的焊劑。福建特種焊絲工廠</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。浙江鈷基焊絲廠藥芯焊絲中的藥粉成分一般與焊條藥皮相似。</p><div

對本實用新型作進一步說明：結(jié)合圖1—圖4所示，一種防腐罐用焊條自動生產(chǎn)設(shè)備，由塑料擠出機a、水冷循環(huán)系統(tǒng)b、自動切斷機構(gòu)c、焊條接斗d組成，四者從前到后依次布置。水冷循環(huán)系統(tǒng)b，主要由機架1、水槽2、焊條導向桿3、水龍頭4、水管5和水泵組成。機架1上方設(shè)置有長條形的水槽2，水槽2由水平隔板分割成上層槽2a和下層槽，上層槽2a呈敞開狀態(tài)，下層槽為封閉狀態(tài)。在水槽2的兩端設(shè)置有連通槽2c。上層槽2a的前壁、后壁上對應(yīng)開設(shè)有焊條過孔2b，焊條過孔的直徑為等邊三角形焊條19邊長的兩倍到三倍之間，供從塑料擠出機出來的焊條通過，同時還能確保上層槽2a的冷卻水由焊條過孔2b流入連通槽2c。限定焊條過孔的直徑與等邊三角形焊條邊長之間的關(guān)系，既能確保對焊條位置的限定，又能確保水流量。在上層槽2a內(nèi)前后間隔安裝有兩根水平設(shè)置的焊條導向桿3，但不限于兩根，對通過的焊條進行導向。焊條過孔2b、焊條導向桿3在高度上齊平，確保焊條在水冷過程中水平地順暢通過，防止焊條彎曲變形。上層槽2a的冷卻水能經(jīng)焊條過孔2b流入連通槽2c，并**終流進下層槽，再由水泵將下層槽的水泵入與水龍頭4相連的水管5。水龍頭4位于上層槽2a的前壁上方并正對焊條過孔2b。</p><p>

分別是焊條的送進運動、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2—焊條擺動3—沿焊縫移動(1)焊條的送進運動。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，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)細長的焊縫；焊接速度適中時，才能焊成表面平整，焊波細致而均勻的焊縫。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。需要彎曲加工的焊接接頭，一般加工性受塑性的影響，而塑性隨著強度的增大而降低。福建特種焊絲工廠</p><p
