盡量選擇小電流焊接，因?yàn)樵陔娏魈髸r(shí)，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(hù)不好，出現(xiàn)氣孔等缺點(diǎn)，同時(shí)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(shí)，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(shí)，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(yùn)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(diǎn)：在焊縫的兩邊稍作停頓，中間過度要**.月牙形運(yùn)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(diǎn)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）。?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(qiáng)度的增大而降低。</p><div
