焊接工藝評定簡介
焊接工藝評定(Welding Procedure Qualification Record,簡稱WPQR)為驗證所擬定的焊件焊接工藝的正確性而進(jìn)行的試驗過程及結(jié)果評價。
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)標(biāo)準(zhǔn)或行業(yè)標(biāo)準(zhǔn)、技術(shù)規(guī)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(guī)程(WPS或pWPS)是否正確。
3.為制定正式的焊接工藝指導(dǎo)書或焊接工藝卡提供可靠的技術(shù)依據(jù)。
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(jié)構(gòu)等鋼制設(shè)備的制造、安裝、檢修工作
⒉.適用于氣焊,焊條電弧焊,鎢極氬弧焊,熔化極氣體保護(hù)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。
焊接工藝評定過程
1.預(yù)焊接工藝指導(dǎo)書(Preliminary Welding Procedure Specification,簡稱PWPS);
⒉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足標(biāo)準(zhǔn)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(dǎo)書進(jìn)行評定。
