焊條電弧焊從焊接電弧的基礎(chǔ)講起，按“有認知、易學(xué)會、好掌握、能操作”的原則，由淺入深、循序漸進地講解了焊條電弧焊的工藝理論和實操技能。本書主要內(nèi)容包括：焊接技術(shù)基礎(chǔ)知識、焊條電弧焊設(shè)備、焊條的組成和分類、焊條的型號與牌號、常用焊條焊接工藝性能及選用原則、焊條的正確保管與貯存、焊條電弧焊基本工藝知識、焊接冶金基本知識、焊接接頭的組.織與性能、焊條電弧焊常見焊接缺點及其防止、典型管類和管板類焊接技術(shù)、碳弧氣刨。一、焊條電弧焊的操作焊條電弧焊**基本的操作是引弧、運條和收尾(一)引弧引弧即產(chǎn)生電弧。焊條電弧焊是采用低電壓、大電流放電產(chǎn)生電弧，依靠電焊條瞬時接觸工件實現(xiàn)。引弧時必須將焊條末端與焊件表面接觸形成短路，然后迅速將焊條向上提起2～4mm的距離，此時電弧即引燃。引弧的方法有兩種：碰擊法和擦劃法，詳見圖3—14引弧方法(1)碰擊法。也稱點接觸法或稱敲擊法。碰擊法是將焊條與工件保持一定距離，然后垂直落下，使之輕輕敲擊工件，發(fā)生短路，再迅速將焊條提起，產(chǎn)生電弧的引弧方法。此種方法適用于各種位置的焊接。(2)擦劃法。也稱線接觸法或稱摩擦法。擦劃法是將電焊條在坡口上滑動，成一條線，當端部接觸時，發(fā)生短路。江蘇RD12M焊絲供應(yīng)商選擇具有熔化溫度低于母材的填充金屬，可**減小熱影響區(qū)中晶間裂紋傾向。</p><div

因接觸面很小，溫度急劇上升，在未熔化前，將焊條提起，產(chǎn)生電弧的引弧方法。此種方法易于掌握，但容易沾污坡口，影響焊接質(zhì)量。上述兩種引弧方法應(yīng)根據(jù)具體情況靈活應(yīng)用。擦劃法引弧雖比較容易，但這種方法使用不當時，會擦傷焊件表面。為盡量減少焊件表面的損傷，應(yīng)在焊接坡口處擦劃，擦劃長度以20～25mm為宜。在狹窄的地方焊接或焊件表面不允許有劃傷時，應(yīng)采用碰擊法引弧。碰擊法引弧較難掌握，焊條的提起動作太快并且焊條提得過高，電弧易熄滅；動作太慢，會使焊條粘在工件上。當焊條一旦粘在工件上時，應(yīng)迅速將焊條左右擺動，使之與焊件分離；若仍不能分離時，應(yīng)立即松開焊鉗切斷電源，以免短路時間過長而損壞電焊機。(3)引弧的技術(shù)要求。在引弧處，由于鋼板溫度較低，焊條藥皮還沒有充分發(fā)揮作用，會使引弧點處的焊縫較高，熔深較淺，易產(chǎn)生氣孔，所以通常應(yīng)在焊縫起始點后面10mm處引弧，如圖3—15。引燃電弧后拉長電弧，并迅速將電弧移至焊縫起點進行預(yù)熱。預(yù)熱后將電弧壓短，酸性焊條的弧長約等于焊條直徑，堿性焊條的弧長應(yīng)為焊條直徑的一半左右，進行正常焊接。采用上述引弧方法即使在引弧處產(chǎn)生氣孔，也能在電弧第二次經(jīng)過時，將這部分金屬重新熔化。焊接接頭的強度隨著焊絲的合金元素含量變化。</p><div

使水龍頭4出來的水淋在上層槽2a的前側(cè)板上并分別濺入上層槽2a和連通槽2c，從而實現(xiàn)冷卻水的循環(huán)利用。水龍頭4在焊條進入上層槽2a的前方位置處進行噴淋冷卻水，提前對焊條進行預(yù)冷卻，同時在焊條進入上層槽2a后再次進行噴淋冷卻水，能有效防止焊條驟冷變形。比較好是，上層槽2a的前壁頂部設(shè)置有高于焊條過孔2b的溢水缺口2d，上層槽2a的冷卻水還能經(jīng)溢水缺口2d流入連通槽2c。另外，連通槽2c的橫截面呈三角形，以騰出空間使焊條從連通槽2c的上方通過。自動切斷機構(gòu)c，主要由工作臺12、安裝架13、立塊14、焊條導(dǎo)向管15、“門”形安裝架16、豎直氣缸6、焊條切斷刀7、螺栓8、上導(dǎo)向膠輪9和下導(dǎo)向膠輪10、限位柱11組成。工作臺12上安裝有上導(dǎo)向膠輪9和下導(dǎo)向膠輪10。上導(dǎo)向膠輪9和下導(dǎo)向膠輪10的中部分別設(shè)置有環(huán)向缺槽，且兩個環(huán)向凹槽正好圍成供橫截面為等邊三角形的焊條通過的通道，上導(dǎo)向膠輪9和下導(dǎo)向膠輪10轉(zhuǎn)動的同時，帶動焊條向后移動。在通道的正前方設(shè)置有左、右兩根限位柱11，供焊條從中穿過，左、右限位柱11通過“l(fā)”形板安裝到工作臺12上。工作臺12的后壁上安裝有安裝架13，安裝架13呈“7”字形并朝向后方。安裝架13的這種安裝方式，是為了讓切斷后的焊條能自動下落。對各種鋼材的焊接，適應(yīng)性強調(diào)整焊劑的成分和比例極為方便和容易，可以提供所要求的焊縫化學(xué)成分。江蘇RD12M焊絲供應(yīng)商</p><p

且焊縫寬度較窄。在正常的焊接速度下，焊波飽滿平整。此法適用于板厚3～5mm的不開坡口的對接平焊、多層焊的***層焊道和多層多道焊。2)直線往返形運條法。此法是焊條末端沿焊縫的縱向作來回直線形擺動，如圖3—18所示，主要適用于薄板焊接和接頭間隙較大的焊縫。其特點是焊接速度快，焊縫窄，散熱快。直線往返形運條法3)鋸齒形運條法。此法是將焊條末端作鋸齒形連續(xù)擺動并向前移動，如圖3—19所示，在兩邊稍停片刻，以防產(chǎn)生咬邊缺點。這種手法操作容易、應(yīng)用較廣，多用于比較厚的鋼板的焊接，適用于平焊、立焊、仰焊的對接接頭和立焊的角接接頭。鋸齒形運條法4)月牙形運條法。如圖3—20所示，此法是使焊條末端沿著焊接方向作月牙形的左右擺動，并在兩邊的適當位置作片刻停留，以使焊縫邊緣有足夠的熔深，防止產(chǎn)生咬邊缺點。此法適用于仰、立、平焊位置以及需要比較飽滿焊縫的地方。其適用范圍和鋸齒形運條法基本相同，但用此法焊出來的焊縫余高較大。其優(yōu)點是，能使金屬熔化良好，而且有較長的保溫時間，熔池中的氣體和熔渣容易上浮到焊縫表面，有利于獲得高質(zhì)量的焊縫。月牙形運條法5)三角形運條法。如圖3—21所示，此法是使焊條末端作連續(xù)三角形運動，并不斷向前移動。江蘇激光焊絲廠</p><p
