氧化性酸、有機(jī)酸、氣蝕）耐熱和耐蝕性能。通常被選作電站、化工、石油等設(shè)備材料。但鉻不銹鋼一般情況下可焊性較差，應(yīng)注意焊接工藝、熱處理?xiàng)l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(yīng)用于化工、化肥、石油、醫(yī)療機(jī)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(guò)長(zhǎng)，層間快冷，以窄焊道為宜。不銹鋼焊接要點(diǎn)與注意事項(xiàng)一、采用垂直外特性的電源，直流時(shí)采用正極性(焊絲接負(fù)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(diǎn)。（感謝關(guān)注鼎鼎自動(dòng)焊接）2、保護(hù)氣體為氬氣，純度為。當(dāng)焊接電流為50~150A時(shí)，氬氣流量為8~10L/min，當(dāng)電流為150~250A時(shí)，氬氣流量為12~15L/min。3、鎢極從氣體噴嘴突出的長(zhǎng)度，以4~5mm為佳，在角焊等遮蔽性差的地方是2~3mm，在開(kāi)槽深的地方是5~6mm，噴嘴至工作的距離一般不超過(guò)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(wù)必清理干凈。5、焊接電弧長(zhǎng)度，焊接普通鋼時(shí)，以2~4mm為佳，而焊接不銹鋼時(shí)，以1~3mm為佳，過(guò)長(zhǎng)則保護(hù)效果不好。6、對(duì)接打底時(shí)，為防止底層焊道的背面被氧化，背面也需要實(shí)施氣體保護(hù)。安徽GZ60S焊絲價(jià)格焊劑為堿性系統(tǒng)的焊材可使熔填金屬獲得非常優(yōu)良的延性與韌性，但作業(yè)性遠(yuǎn)較酸性系為差。</p><div

分別是焊條的送進(jìn)運(yùn)動(dòng)、焊條的橫向擺動(dòng)運(yùn)動(dòng)和焊條的沿焊縫移動(dòng)運(yùn)動(dòng)，詳見(jiàn)圖3—16。焊條的三個(gè)基本運(yùn)動(dòng)1—焊條送進(jìn)2—焊條擺動(dòng)3—沿焊縫移動(dòng)(1)焊條的送進(jìn)運(yùn)動(dòng)。主要是用來(lái)維持所要求的電弧長(zhǎng)度。由于電弧的熱量熔化了焊條端部，電弧逐漸變長(zhǎng)，有熄弧的傾向。要保持電弧繼續(xù)燃燒，必須將焊條向熔池送進(jìn)，直至整根焊條焊完為止。為保證一定的電弧長(zhǎng)度，焊條的送進(jìn)速度應(yīng)與焊條的熔化速度相等，否則會(huì)引起電弧長(zhǎng)度的變化，影響焊縫的熔寬和熔深。(2)焊條的擺動(dòng)和沿焊縫移動(dòng)。這兩個(gè)動(dòng)作是緊密相聯(lián)的，而且變化較多、較難掌握。通過(guò)兩者的聯(lián)合動(dòng)作可獲得一定寬度、高度和一定熔深的焊縫。所謂焊接速度即單位時(shí)間內(nèi)完成的焊縫長(zhǎng)度。如圖3—17，表示焊接速度對(duì)焊縫成形的影響。焊接速度太慢，會(huì)焊成寬而局部隆起的焊縫；太快，會(huì)焊成斷續(xù)細(xì)長(zhǎng)的焊縫；焊接速度適中時(shí)，才能焊成表面平整，焊波細(xì)致而均勻的焊縫。焊接速度對(duì)焊縫成形的影響(3)運(yùn)條手法。為了控制熔池溫度，使焊縫具有一定的寬度和高度，在生產(chǎn)中經(jīng)常采用下面幾種運(yùn)條手法。1)直線形運(yùn)條法。采用直線形運(yùn)條法焊接時(shí)，應(yīng)保持一定的弧長(zhǎng)，焊條不擺動(dòng)并沿焊接方向移動(dòng)。由于此時(shí)焊條不作橫向擺動(dòng)，所以熔深較大。</p><p> 且焊縫寬度較窄。在正常的焊接速度下，焊波飽滿平整。此法適用于板厚3～5mm的不開(kāi)坡口的對(duì)接平焊、多層焊的***層焊道和多層多道焊。2)直線往返形運(yùn)條法。此法是焊條末端沿焊縫的縱向作來(lái)回直線形擺動(dòng)，如圖3—18所示，主要適用于薄板焊接和接頭間隙較大的焊縫。其特點(diǎn)是焊接速度快，焊縫窄，散熱快。直線往返形運(yùn)條法3)鋸齒形運(yùn)條法。此法是將焊條末端作鋸齒形連續(xù)擺動(dòng)并向前移動(dòng)，如圖3—19所示，在兩邊稍停片刻，以防產(chǎn)生咬邊缺點(diǎn)。這種手法操作容易、應(yīng)用較廣，多用于比較厚的鋼板的焊接，適用于平焊、立焊、仰焊的對(duì)接接頭和立焊的角接接頭。鋸齒形運(yùn)條法4)月牙形運(yùn)條法。如圖3—20所示，此法是使焊條末端沿著焊接方向作月牙形的左右擺動(dòng)，并在兩邊的適當(dāng)位置作片刻停留，以使焊縫邊緣有足夠的熔深，防止產(chǎn)生咬邊缺點(diǎn)。此法適用于仰、立、平焊位置以及需要比較飽滿焊縫的地方。其適用范圍和鋸齒形運(yùn)條法基本相同，但用此法焊出來(lái)的焊縫余高較大。其優(yōu)點(diǎn)是，能使金屬熔化良好，而且有較長(zhǎng)的保溫時(shí)間，熔池中的氣體和熔渣容易上浮到焊縫表面，有利于獲得高質(zhì)量的焊縫。月牙形運(yùn)條法5)三角形運(yùn)條法。如圖3—21所示，此法是使焊條末端作連續(xù)三角形運(yùn)動(dòng)，并不斷向前移動(dòng)。主要用于工件表面的手工堆焊，以滿足如抗氧化、耐磨損和高溫下耐腐蝕等特殊性能要求。</p><div
