原標(biāo)題：焊不銹鋼用什么焊條？不銹鋼怎么焊接？焊接是被焊工件的材質(zhì)(同種或異種),通過(guò)加熱或加壓或兩者并用,并且用或不用填充材料,使工件的材質(zhì)達(dá)到原子間的結(jié)合而形成長(zhǎng)久性連接的工藝過(guò)程。那么不銹鋼焊接要點(diǎn)與注意事項(xiàng)有哪些要點(diǎn)呢?焊不銹鋼用什么焊條不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條,這兩類焊條中凡符合國(guó)標(biāo)的,均按國(guó)標(biāo)GB/T983-2012規(guī)定考核。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(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)。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。上海TM-2000焊條焊絲供貨廠工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護(hù)，獲得良好成形。</p><div
