焊縫金屬射線探傷要求：Ⅰ級
注意事項及操作要點：
1. 焊接處須徹底清除油污、鐵銹、水份等表面雜質，以防止焊接時產生氣孔、裂紋等，清理時，坡口面及周圍要磨出金屬光澤。
2. 焊前應清除焊絲表面的油、垢及銹等污物。
3. 為使焊縫獲得良好的機械性能，MIG焊接的保護氣體建議采用Ar+2%O2，保護氣體流量以20-25L/min為優。TIG焊接的保護氣體建議采用純氬氣保護，純度要在99.99%以上，保護氣體流量以8-15L/min為宜。
4. 在焊接過程中，焊接線能量的大小直接影響焊縫金屬的力學性能及抗裂性能等，應引起更多關注。
5. 以上焊接方法、條件及規范的建議僅供參考，用戶在將焊絲用于正式產品焊接前應根據自身焊接特點進行工藝評定。
