原標題：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(同種或異種),通過加熱或加壓或兩者并用,并且用或不用填充材料,使工件的材質達到原子間的結合而形成長久性連接的工藝過程。那么不銹鋼焊接要點與注意事項有哪些要點呢?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標的,均按國標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。焊絲是作為填充金屬或同時作為導電用的金屬絲焊接材料。</p><div

藥芯焊絲焊接時比CO2實芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實芯焊絲飛濺大小的比較。焊接質量好一般CO2實芯焊絲只適合于低碳鋼或強度級別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結構鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實芯焊絲有了很大的提高，可適用于各種重要結構的焊接，而CO2實芯焊絲一般只用于0度以上工作的一般鋼結構。綜合焊接成本：低藥芯焊絲相對價格較高，但其綜合生產成本比焊條電弧焊要低許多，與CO2實芯焊絲大體相當。藥芯焊絲的型號及牌號按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號，代號后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號后面的第二位數(shù)字或英文字母為分類代號。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學性能。如焊絲型號EF03-5042。實際生產中還經常用牌號來表示藥芯焊絲的類型。藥芯焊絲生產牌號用如下符號表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，***、第二位數(shù)字表示焊絲特點；第三位數(shù)字表示溶渣類型（或第三位以后之數(shù)字及元素符號表示焊縫金屬化學成分）。若外觀顏色匹配是重要指標時，選擇焊絲時必須考慮所形成焊縫組.織的成分及組.織。南京卡博焊條焊絲供應商</p><p
