放射性氣溶膠是造成人體內(nèi)照射的主要威脅。強電弧光的危害焊接弧光輻射主要有可見光、紅外線和紫外線。它們作用到人體上，被人體組.織吸收，引起組.織的熱作用、光化學(xué)作用或電離作用，使人體組.織受到損傷?？梢姽饩€的光度比肉眼正常承受的光度大約大到一萬倍左右，當(dāng)可見光線輻射人的眼睛時，會產(chǎn)生疼痛感，看不清東西，通常叫“晃眼”，在短時間內(nèi)失去勞動能力。紅外線對人體的危害主要是引起組.織的熱作用。在焊接過程中，眼部受到強烈的紅外線輻射，會立即感到強烈的灼傷和灼痛，發(fā)生閃光幻覺。長期接觸可能造成紅外線白內(nèi)障、視力減退，嚴(yán)重時可導(dǎo)致失明。紫外輻射(ultravioletradiation，UV)又稱紫外線，是指波長在100—400nm的電磁波。適量的紫外線照射可以對人體產(chǎn)生有益的作用，但是過量照射會對人體造成不良的影響(如電焊紫外輻射)。紫外線對人體的危害主要是光化學(xué)作用，對人體皮膚和眼睛造成損害。皮膚受到強烈的紫外線輻射后，可引起皮炎，彌漫性紅斑，有時出現(xiàn)小水泡、滲出液，有燒灼感，發(fā)癢；作用強烈時伴有全身癥狀：***、頭暈、易疲勞、神經(jīng)興奮、發(fā)燒、***等。紫外線過度照射人的眼睛，可引起眼睛急性角膜和結(jié)膜炎，即電光眼炎。江西激光焊絲廠自保護藥芯焊絲，是在氣保護藥芯焊絲問市不久，便被發(fā)展出來，也很快的被工業(yè)界廣為認同于特定的用途上。</p><div

使氣孔消除，并且不會留引弧傷痕。為了保證焊縫起點處能夠焊透，焊條可作適當(dāng)?shù)臋M向擺動，并在坡口根部兩側(cè)稍加停頓，以形成一定大小的熔池。引弧點的選擇引弧對焊接質(zhì)量有一定的影響，經(jīng)常因為引弧不好而造成始焊的缺點。綜上所述，在引弧時應(yīng)做到以下幾點：(1)工件坡口處無油污、銹斑，以免影響導(dǎo)電能力和防止熔池產(chǎn)生氧化物。(2)在接觸時，焊條提起時間要適當(dāng)。太快，氣體未電離，電弧可能熄滅；太慢，則使焊條和工件粘合在一起，無法引燃電弧。(3)焊條的端部要有裸露部分，以便引弧。若焊條端部裸露不均，則應(yīng)在使用前用銼刀加工，防止在引弧時，碰擊過猛使藥皮成塊脫落，引起電弧偏吹和引弧瞬間保護不良。(4)引弧位置應(yīng)選擇適當(dāng)，開始引弧或因焊接中斷重新引弧，一般均應(yīng)在離始焊點后面10～20mm處引弧，然后移至始焊點，待熔池熔透再繼續(xù)移動焊條，以消除可能產(chǎn)生的引弧缺點。(二)運條電弧引燃后，就開始正常的焊接過程。為獲得良好的焊，縫成形，焊條得不斷地運動。焊條的運動稱為運條。運條是電焊工操作技術(shù)水平的具體表現(xiàn)。焊縫質(zhì)量的優(yōu)劣、焊縫成形的好壞，主要由運條來決定。運條由三個基本運動合成。</p><p>

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。安徽模具焊絲銷售廠</p><p
