按適用范圍不同，可分為斜三角形和正三角形兩種運條方法。其中斜三角形運條法適用于焊接T形接頭的仰焊縫和有坡口的橫焊縫。其特點是能夠通過焊條的擺動控制熔化金屬，促使焊縫成形良好。正三角形運條法*適用于開坡口的對接接頭和T形接頭的立焊。其特點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。三角形運條法6)圓圈形運條法。如圖3—22所示，將焊條末端連續(xù)作圓圈運動，并不斷前進(jìn)。這種運條方法又分正圓圈和斜圓圈兩種。正圓圈運條法只適于焊接較厚工件的平焊縫，其優(yōu)點是能使熔化金屬有足夠高的溫度，有利于氣體從熔池中逸出，可防止焊縫產(chǎn)生氣孔。斜圓圈運條法適用于T形接頭的橫焊(平角焊)和仰焊以及對接接頭的橫焊縫，其特點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。圓圈形運條法(三)收尾電弧中斷和焊接結(jié)束時，應(yīng)把收尾處的弧坑填滿。若收尾時立即拉斷電弧，則會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，因此焊縫完成時的收尾動作不*是熄滅電弧，而且要填滿弧坑。收尾動作有以下幾種：(1)劃圈收尾法。焊條移至焊縫終點時，作圓圈運動，直到填滿弧坑再拉斷電弧。</p><div

注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號舉例如下：例14、焊條的選用（1）結(jié)構(gòu)鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結(jié)構(gòu)鋼制造的焊接結(jié)構(gòu)，大多要求焊縫金屬與母材等強度，此時可按結(jié)構(gòu)鋼的強度選擇相應(yīng)強度等級的焊條。選擇時應(yīng)注意以下兩點：1）鋼材的強度等級是按屈服點劃分的，而結(jié)構(gòu)鋼焊條的強度等級系指其抗拉強度的比較低保證值，兩者是不一致的。通常應(yīng)選擇抗拉強度保證值與母材相同或稍高的焊條。2）焊縫強度不是比母材高出愈多愈好，而應(yīng)等于或稍高于母材。如果焊縫強度過高，往往使焊縫的塑性下降，反而有害。當(dāng)焊接接頭不要求焊縫與其等強度時，可選用抗拉強度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強度。但如果母材是耐熱鋼、耐腐蝕鋼時，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時，應(yīng)根據(jù)母材的化學(xué)成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S、P等雜質(zhì)較高時，很容易在焊縫中形成裂紋。</p></p><br
