    焊縫金屬射線探傷要求:Ⅰ級(jí)  

    注意事項(xiàng)及操作要點(diǎn):

    1. 焊接處須徹底清除油污、鐵銹、水份等表面雜質(zhì),以防止焊接時(shí)產(chǎn)生氣孔、裂紋等,清理時(shí),坡口面及周圍要磨出金屬光澤。

    2. 焊前應(yīng)清除焊絲表面的油、垢及銹等污物。

    3. 為使焊縫獲得良好的機(jī)械性能,MIG焊接的保護(hù)氣體建議采用Ar+2%O2,保護(hù)氣體流量以20-25L/min為優(yōu)。TIG焊接的保護(hù)氣體建議采用純氬氣保護(hù),純度要在99.99%以上,保護(hù)氣體流量以8-15L/min為宜。

    4. 在焊接過(guò)程中,焊接線能量的大小直接影響焊縫金屬的力學(xué)性能及抗裂性能等,應(yīng)引起更多關(guān)注。

    5. 以上焊接方法、條件及規(guī)范的建議僅供參考,用戶在將焊絲用于正式產(chǎn)品焊接前應(yīng)根據(jù)自身焊接特點(diǎn)進(jìn)行工藝評(píng)定。
