補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型坡口角度不應小于60°～70°。板厚超過14mm時，焊前焊件表面應仔細清理，***一切會產(chǎn)生氫氣的油類雜質(zhì)。操作時應當用短弧焊接，焊條不做橫向和前后擺動，只沿焊縫的直線移動。焊接速度要快，不應低于～。多層焊時，層與層之間的氧化膜及渣應***干凈。黃銅的銅液流動性大，故溶池比較好處于水平位置，若溶池必須傾斜，則傾角不應大于15°3．黃銅的手工氬弧焊手工鎢極氬弧焊時，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，鋅的蒸發(fā)比直流正接時輕。通常焊前不用預熱，只有板厚相差比較大時才預熱。焊接速度應盡可能快。焊件在焊后應加熱300~400℃進行退火處理，消除焊接應力，以防止焊件在使用過程中裂縫。由于鋅的蒸發(fā)破壞氬氣的保護效果，所以焊接黃銅時應選用較大的噴嘴孔徑和氬氣流量。焊前一般不預熱，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才需預熱。RD12M焊絲訂購焊絲焊補時熱影響區(qū)非常小，不會產(chǎn)生內(nèi)應力。</p><div

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、光化學作用或電離作用，使人體組.織受到損傷。可見光線的光度比肉眼正常承受的光度大約大到一萬倍左右，當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，嚴重時可導致失明。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。</p><p>

不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條。鉻不銹鋼具有一定的耐蝕（氧化性酸、有機酸、氣蝕）耐熱和耐蝕性能。通常被選作電站、化工、石油等設備材料。但鉻不銹鋼一般情況下可焊性較差，應注意焊接工藝、熱處理條件及選用合適的電焊條。鉻鎳不銹鋼焊條具有良好耐腐蝕性和抗氧化性，廣泛應用于化工、化肥、石油、醫(yī)療機械制造。為防止由于加熱而產(chǎn)生晶間腐蝕，焊接電流不宜太大，比碳鋼焊條較少20%左右，電弧不宜過長，層間快冷，以窄焊道為宜。不銹鋼焊接要點與注意事項一、采用垂直外特性的電源，直流時采用正極性(焊絲接負極)1、一般適合于6mm以下薄板的焊接，具有焊縫成型美觀，焊接變形量小的特點。2、保護氣體為氬氣，純度為。當焊接電流為50~150A時，氬氣流量為8~10L/min，當電流為150~250A時，氬氣流量為12~15L/min。3、鎢極從氣體噴嘴突出的長度，以4~5mm為佳，在角焊等遮蔽性差的地方是2~3mm，在開槽深的地方是5~6mm，噴嘴至工作的距離一般不超過15mm。4、為防止焊接氣孔之出現(xiàn)，焊接部位如有鐵銹、油污等務必清理干凈。5、焊接電弧長度，焊接普通鋼時，以2~4mm為佳，而焊接不銹鋼時，以1~3mm為佳，過長則保護效果不好。6、對接打底時。RD12M焊絲訂購</p><p
