摘要
介绍了焊接工艺评定标准、焊接试样的制备及试验方法。通过焊条电弧立焊工艺试验验证SA-738Gr.B钢的焊接工艺是否满足标准要求。对焊接试样进行了无损检测、力学性能试验、宏微观形貌观察及化学成分分析。结果表明,采用拟定的工艺参数焊接的接头各项性能能够满足标准要求。
The welding procedure qualification standard, the preparation of welding samples and test methods were introduced.The welding process of SA-738Gr.B steel was verified by process test of electrode are vertical welding. The nondestructive test, mechanical property test, macro and micro morphologies observation and chemical composition analysis of welded specimens were carried out. The results show that the performance of the welded joint using the proposed process parameters can meet the standard requirements.
