焊接工藝評定WPQR

焊接工藝評定簡(jiǎn)介
焊接工藝評定(Welding Procedure Qualification Record,簡(jiǎn)稱(chēng)WPQR) 為驗證所擬定的焊件焊接工藝的正確性而進(jìn)行的試驗過(guò)程及結果評價(jià)。


焊接工藝評定目的


1. 評定施焊單位是否有能力焊出符合相關(guān)國家或行業(yè)標準、技術(shù)規范所要求的焊接接頭;
2. 驗證施焊單位所擬訂的焊接工藝規程(WPS或pWPS)是否正確。
3. 為制定正式的焊接工藝指導書(shū)或焊接工藝卡提供可靠的技術(shù)依據。


歐盟焊接工藝評定適用范圍


1. 適用于鍋爐,壓力容器,壓力管道,橋梁,船舶,航天器,核能以及承重鋼結構等鋼制設備的制造、安裝、檢修工作;
2. 適用于氣焊,焊條電弧焊,鎢極氬弧焊,熔化極氣體保護焊,埋弧焊,等離子弧焊,電渣焊,螺柱焊,激光焊,壓力焊等焊接方法。


焊接工藝評定過(guò)程


1. 預焊接工藝指導書(shū)(Preliminary Welding Procedure Specification,簡(jiǎn)稱(chēng)PWPS);
2. 施焊試件和制取試樣;
3. 檢驗試件和試樣;
4. 測定焊接接頭是否滿(mǎn)足標準所要求的使用性能;
5. 提出焊接工藝評定報告對擬定的焊接工藝指導書(shū)進(jìn)行評定。
