                符合(相當)相關(guān)標準型號:

                GB/T 29713-2013 S347 ISO 14343-B:2009 SS347 AWS A5.9 ER-347 

                說(shuō)明:SD-TIG347是低碳Cr20Ni10Nb型的不銹鋼鎢極氬弧焊絲。由于含鈮穩定劑,可防止晶間析出碳化鉻,具有優(yōu)良的抗晶間腐蝕性能。全位置焊接性能良好。

                用途:適用于焊接07Cr19 Ni11Ti(SUS 321)、07Cr18Ni11Nb(SUS 347)不銹鋼,如石油化工等設備的焊接。

                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。
