      發布時間:2020-01-11

      焊接工藝評定工作是整個焊接工作的前期準備,是驗證所擬定的焊件及有關產品的焊接工藝的正確性而進行的試驗過程和結果評價,重要性不言而喻。

      PQR焊接工藝評定試驗常用標準:

      ASME Ⅸ

      ISO 15614-1& ISO 15614-2

      AWS D 1.1&AWS D1.2

      AS 1544.1

      NB/T 47014-016-2011

      PQR焊接工藝評定試驗項目:

      試驗項目:外觀檢查,無損檢測,力學性能和彎曲性能試驗,金相檢驗(宏觀)

      注:*可以用4個側彎試樣代替2個面彎和2個背彎試樣;制取試樣允許避開試件上的缺陷;試樣去除焊縫余高前允許進行冷校平。
