盡量選擇小電流焊接，因為在電流太大時，易造成熔池翻滾，不僅飛濺大，成形也很差。6、焊接速度：對焊縫內(nèi)部與外觀的質(zhì)量都有重要影響。焊速過快會使氣體保護不好，出現(xiàn)氣孔等缺點，同時焊縫的冷卻速度相應(yīng)提高，因而降低了焊縫金屬的塑性的韌性。焊速過慢時，熔池變大，焊縫變寬，易因過熱造成焊縫金屬組.織粗大或燒穿。7、噴嘴與工件的角度：當(dāng)噴嘴與工件垂直時，飛濺會很大，電弧不穩(wěn)。為避免這種情況的出現(xiàn)，可將噴嘴后傾10-15度（焊接位置不同，焊角度也不同），即可保證焊縫成形良好，焊接過程穩(wěn)定。8、運條方法：1.直線法，直線往復(fù)法。（適合小而窄的焊縫）。2.鋸齒形（適合寬焊縫），操作要點：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運條法（同鋸齒形）。以下幾種不宜掌握，知道就可以，三角形（斜三角，正三角），圓圖形（斜圓圖，正圓圖），八字形。七、焊接手法及焊接缺點產(chǎn)生的原因1.平焊（以右手向左焊，焊縫成形好，容易觀察熔池成形情況。角度大約45度;以右手向右焊，焊縫成形差）。江蘇H13焊條焊絲價格?有些合金，如鈷鉻鎢合金，不能鍛、軋和拔絲，而用鑄造方法制成。</p><div

焊接時聽到沙……沙的聲音，（小電流時聲音是滋滋聲）。焊接時焊機的電流表，電壓表的指針穩(wěn)定，擺動小。2.比較好規(guī)范的調(diào)整方法：根據(jù)焊件厚度，焊縫位置，選擇焊絲直徑，氣體流量，焊接電流。在試板上試焊，根據(jù)選擇的送絲速度，細心調(diào)整焊接電壓，比較好的浮動焊接電壓一般在1-2V之間。根據(jù)試板上焊縫成形情況，適當(dāng)調(diào)整送絲速度，焊接電壓，達到比較好焊接規(guī)范。在工件上正式焊接過程中，應(yīng)注意焊接回路，接觸電阻引起的電壓降，及時調(diào)整（微調(diào)）焊接電壓，確保焊接過程穩(wěn)定。3.焊接規(guī)范匹配不良的焊接現(xiàn)象及排除：當(dāng)焊絲端頭始終有滴狀金屬小球存在，且過度頻率偏低，此情況說明焊接電壓偏高，此時應(yīng)加快焊絲速度或降低焊接電壓。當(dāng)焊絲干伸偏短時能正常焊接，稍長就出現(xiàn)頂絲現(xiàn)象，說明焊接電壓偏低，此時應(yīng)通過降低送絲速度或升高焊接電壓。4、調(diào)試焊接參數(shù)時應(yīng)注意以下幾點：先把送絲速度調(diào)低點。再調(diào)焊接電壓，焊接電流應(yīng)根據(jù)焊接母材的厚度來控制。再調(diào)送絲速度，這時把送絲調(diào)到正好（電弧能夠把焊絲溶解，且溶解的很舒服）。聽聲音，看飛濺。如果溶解的很舒服，聲音是很平穩(wěn)的，不會乒乓作響，飛濺也少。5、在保證焊縫熔透（這里不是焊穿的意思）的情況下。</p><p>
