                符合(相當)相關(guān)標準型號:

                GB/T 29713-2013 S2209 ISO 14343-B:2009 SS2209 AWS A5.9 ER2209 

                說(shuō)明:SD-TIG2209是Cr22Ni8Mo3N型的奧氏體鐵素體雙相不銹鋼鎢極氬弧焊絲。熔敷金屬具有奧氏體不銹鋼的綜合性能和鐵素體不銹抗應力腐蝕特性。

                用途:適用于石油化工、船舶制造等行業(yè),如022Cr22Ni5Mo3N(SUS 2205)材料的焊接。

                注意事項:

                1. 1、焊前必須對焊件清除鐵銹、鍍層、油污、水分和雜質(zhì)等污染物。

                2. 2、焊接時(shí)環(huán)境風(fēng)速應小于1m/s。有風(fēng)處應采取擋風(fēng)措施焊接。

                3. 3、應使用焊接用的氬氣,Ar≥99.99%。

                4. 4、當焊縫背面充氬氣時(shí),氣體流量應是正面的1/2,以免形成背面正壓而產(chǎn)生根部未焊透。
