基于焊接工艺评定规则的承压设备焊接质量管理

Welding Quality Management of Pressure Equipment Based on Welding Procedure Qualification Rules

从母材、填充材料、焊接方法和焊后热处理4个方面介绍了焊接工艺评定规则在实际焊接工艺工作中容易出现偏差的部分,并提出了相应的改进措施和注意事项。最后根据焊接工艺评定中的影响因素建立焊接工艺评定汇总表,用于指导实际焊接工作。

Through analyzing the base metal,filling materials,welding method and the postweld heat treatment,the deviations in understanding the welding procedure qualification rules in operation process were described and both improvement measures and matters needing attention were proposed as well as the summary sheet of factors which influencing the welding procedure qualification was established to guide welding operation.
