按適用范圍不同，可分為斜三角形和正三角形兩種運(yùn)條方法。其中斜三角形運(yùn)條法適用于焊接T形接頭的仰焊縫和有坡口的橫焊縫。其特點(diǎn)是能夠通過焊條的擺動(dòng)控制熔化金屬，促使焊縫成形良好。正三角形運(yùn)條法*適用于開坡口的對(duì)接接頭和T形接頭的立焊。其特點(diǎn)是一次能焊出較厚的焊縫斷面，有利于提高生產(chǎn)率，而且焊縫不易產(chǎn)生夾渣等缺點(diǎn)。三角形運(yùn)條法6)圓圈形運(yùn)條法。如圖3—22所示，將焊條末端連續(xù)作圓圈運(yùn)動(dòng)，并不斷前進(jìn)。這種運(yùn)條方法又分正圓圈和斜圓圈兩種。正圓圈運(yùn)條法只適于焊接較厚工件的平焊縫，其優(yōu)點(diǎn)是能使熔化金屬有足夠高的溫度，蘇州H13焊絲供應(yīng)商，有利于氣體從熔池中逸出，可防止焊縫產(chǎn)生氣孔。斜圓圈運(yùn)條法適用于T形接頭的橫焊(平角焊)和仰焊以及對(duì)接接頭的橫焊縫，蘇州H13焊絲供應(yīng)商，其特點(diǎn)是可控制熔化金屬不受重力影響，能防止金屬液體下淌，有助于焊縫成形，蘇州H13焊絲供應(yīng)商。圓圈形運(yùn)條法(三)收尾電弧中斷和焊接結(jié)束時(shí)，應(yīng)把收尾處的弧坑填滿。若收尾時(shí)立即拉斷電弧，則會(huì)形成比焊件表面低的弧坑。在弧坑處常出現(xiàn)疏松、裂紋、氣孔、夾渣等現(xiàn)象，因此焊縫完成時(shí)的收尾動(dòng)作不*是熄滅電弧，而且要填滿弧坑。收尾動(dòng)作有以下幾種：(1)劃圈收尾法。焊條移至焊縫終點(diǎn)時(shí)，作圓圈運(yùn)動(dòng)，直到填滿弧坑再拉斷電弧。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。蘇州H13焊絲供應(yīng)商</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(shí)，焊前焊件表面應(yīng)仔細(xì)清理，***一切會(huì)產(chǎn)生氫氣的油類雜質(zhì)。操作時(shí)應(yīng)當(dāng)用短弧焊接，焊條不做橫向和前后擺動(dòng)，只沿焊縫的直線移動(dòng)。焊接速度要快，不應(yīng)低于～。多層焊時(shí)，層與層之間的氧化膜及渣應(yīng)***干凈。黃銅的銅液流動(dòng)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(shí)，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(shí)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(shí)，鋅的蒸發(fā)比直流正接時(shí)輕。通常焊前不用預(yù)熱，只有板厚相差比較大時(shí)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(shí)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(shí)才需預(yù)熱。</p><p>
