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(guò)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(kāi)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，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，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。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。</p><p> 焊接重要的焊接構(gòu)件及合金鋼焊件，為了防止氫致裂紋的產(chǎn)生，提高焊縫金屬和熱影響區(qū)的韌性，要選用低氫堿性焊條施焊。使用堿性低氫焊條**重要一環(huán)，是焊條的烘干，必須按照烘干要求進(jìn)行，一般焊前烘干工藝要求為350°×1小時(shí)，雨季或潮濕天氣可提高到400°×1小時(shí)。烘干不好，后果很嚴(yán)重，不但會(huì)產(chǎn)生焊接缺點(diǎn)，也會(huì)嚴(yán)重影響焊接工藝性能，千萬(wàn)不要大意！其次，焊件焊接處要清理干凈，徹底***油污、銹跡、水分、雜質(zhì)、臟東西，合理的焊接工藝這一點(diǎn)都寫(xiě)得很清楚。★操作要點(diǎn)堿性低氫焊條的操作，主要是采用短弧操作，電弧盡量壓短。焊接時(shí)，手把要穩(wěn)，電弧越短越好。運(yùn)條時(shí)，焊條傾角與焊縫前進(jìn)方向成85°-90°，與左右保持垂直，如果焊條傾角過(guò)大或左右不正，即使是壓低了電弧，也不是真正的短弧。短弧焊的目的是更好的應(yīng)用渣氣聯(lián)合保護(hù)功能，保護(hù)熔池不受空氣侵襲，保護(hù)熔池焊接冶金反應(yīng)順利進(jìn)行，減少焊接缺點(diǎn)的產(chǎn)生。多層焊時(shí)，每層焊肉要薄些，以利于熔池中氣體逸出，熔渣容易浮出，出現(xiàn)缺點(diǎn)也容易清理。多層焊，每層焊縫方向相反，以利于整體焊縫熱量均勻。操作手法采用畫(huà)圓圈式的橫向擺動(dòng)，熔池冷卻速度變慢，利于氣體逸出，避免產(chǎn)生氣孔，提高焊縫質(zhì)量。通常成卷絲材均以塑膠套包封后并放置干燥劑使避免材料受潮，包封后的材料再放入硬紙盒內(nèi)送出。</p><div

電弧周圍形成多種有害氣體，其中主要有臭氧、氮氧化物、一氧化碳和氟化氫等。臭氧是一種刺激性氣體，呈淡藍(lán)色。濃度較高時(shí)，發(fā)出腥臭味；高濃度臭氧還略帶酸味。臭氧對(duì)人體的主要危害是對(duì)呼吸道及肺有強(qiáng)烈刺激作用。往往引起咳嗽、胸悶、食欲不振、疲勞無(wú)力、頭暈、全身疼痛等，嚴(yán)重時(shí)還會(huì)引起***和肺水腫等。氮氧化物是刺激性氣體。二氧化氮呈紅褐色，具有特殊臭味。氮氧化物對(duì)人體的危害主要是對(duì)肺組.織的刺激作用。其被吸人呼吸道后，在肺泡內(nèi)逐漸與水作用形成硝酸和亞硝酸，對(duì)肺組.織產(chǎn)生強(qiáng)烈刺激和腐蝕作用，引起中毒。慢性中毒的主要癥狀是神經(jīng)衰弱，如***、***、食欲不振、體重下降。濃度高的氮氧化物能引起急性中毒，其中毒輕者，*發(fā)生急性***；重度中毒時(shí)，引發(fā)咳嗽激烈、呼吸困難、虛脫、全身軟弱無(wú)力等癥狀。氮氧化物對(duì)人體的作用也是可逆的，隨著脫離作業(yè)時(shí)間的增長(zhǎng)，其不良影響逐漸減少或消除。在鎢極氬弧焊時(shí)，如果不采取通風(fēng)措施，其濃度往往超過(guò)衛(wèi)生標(biāo)準(zhǔn)十幾倍，甚至幾十倍。我國(guó)規(guī)定的氮氧化物(換算成二氧化氮)的衛(wèi)生標(biāo)準(zhǔn)為5mg／m3。在焊接過(guò)程中，通常臭氧和氮氧化物同時(shí)存在，因此它們的毒性更大。一般情況下。昆山激光焊絲供應(yīng)商</p><p
