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(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，電弧不宜過長，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，蘇州焊絲批發(fā)，具有焊縫成型美觀，焊接變形量小的特點(diǎn)。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(wù)必清理干凈。5、焊接電弧長度，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，蘇州焊絲批發(fā)，過長則保護(hù)效果不好。6、對接打底時(shí)。大多數(shù)焊絲屬于此類，蘇州焊絲批發(fā)，包括碳鋼焊絲、低合金結(jié)構(gòu)鋼焊絲、合金結(jié)構(gòu)鋼焊絲、不銹鋼焊絲和有色金屬焊絲等。蘇州焊絲批發(fā)</p><div

主回路斷電。同時(shí)Jc-2斷開，控制回路斷電，焊機(jī)全部停止工作。焊接電流的調(diào)節(jié)依靠面板上的電流調(diào)節(jié)控制器，來改變磁放大器控制或線圈中直流電大小使鐵芯中的磁通發(fā)生相應(yīng)變化，從而調(diào)整了焊接電流的大小。熱將接線板燒毀或使由焊鉗過熱而無法工作。三、負(fù)載持續(xù)率焊接設(shè)備銘牌中都標(biāo)有負(fù)載持續(xù)率。負(fù)載持續(xù)率是用來表示焊接設(shè)備工作狀態(tài)的參數(shù)，它是在選定的工作時(shí)間周期內(nèi)允許焊接設(shè)備連續(xù)負(fù)載的時(shí)間。眾所周知，焊接設(shè)備工作時(shí)會發(fā)熱，溫升過高會把焊接設(shè)備的線包絕緣燒毀(一般焊接設(shè)備的溫度不得超過60～80℃)。溫升與焊接電流大小有關(guān)，同時(shí)也與焊機(jī)使用狀態(tài)有關(guān)，連續(xù)運(yùn)轉(zhuǎn)與斷續(xù)使用時(shí)溫升情況不一樣。負(fù)載持續(xù)率計(jì)算方法如下：標(biāo)準(zhǔn)規(guī)定：500A以下的焊接設(shè)備選定的工作時(shí)間周期為5分鐘。計(jì)算時(shí)，每個(gè)5分鐘內(nèi)測出電弧燃燒時(shí)間，代入式中即得出焊機(jī)負(fù)載持續(xù)率。表3—3和表3—4給出了交流弧焊機(jī)BX3一300的負(fù)載持續(xù)率和硅整流弧焊機(jī)ZXG一300的負(fù)載持續(xù)率及相應(yīng)的工作電流。表3—3BX3—300交流弧焊機(jī)負(fù)載持續(xù)率負(fù)載持續(xù)率(％)焊接電流(A)表3—4ZXG—300硅整流弧焊機(jī)負(fù)載持續(xù)率負(fù)載持續(xù)率(％)焊接電流(A)四、焊機(jī)的外特性在規(guī)定范圍內(nèi)。昆山鈷基焊絲供應(yīng)商在氣焊和鎢極氣體保護(hù)電弧焊時(shí)，焊絲用作填充金屬。</p><div
