摘要
在Ｑ２３５Ｂ钢高频焊管压扁试验中，对合格与不合格试样的焊缝、母材金相组织进行分析比较，并对焊缝区金相组织的形成原因及其与焊接工艺的关系进行了分析。
In the flattening test of highfrequency welded pipe of Q235B, the metallographic structures of weld and base metal of specimans which reached and unreached the standard are analyzed and compared The generation reason of the metallographic structure in the weld area and its relationship with welding technology are analyzed
