摘　　要：为查明J5 5钢高频焊管焊缝处的冲击功差异较大的原因 ,对母材、焊接热影响区及焊接区进行了微观分析。结果表明 ,冲击功低者 ,其母材、热影响区和焊缝区分别存在较严重的带状组织、粗大的过热组织和夹杂物等。To investigate the reason of the great difference in impact toughness of welding seam of high frequency welding pipe, samples taken from base metal, heat affected zone and welding seam were analyzed through microscopy. The results showed that there was serious band structure in the base metal, overheated structure in heat affected zone and inclusion in welding seam.
