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)標準或行業(yè)標準、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(dǎo)書進行評定。

國際焊工證簡介:
焊工是各種金屬材料制造業(yè)和工業(yè)中的裁縫,他的焊接技能不僅決定了產(chǎn)品的質(zhì)量,更直接涉及到產(chǎn)品使用人員的人身安全。歐盟認為只有擁有合格資質(zhì)的焊工才能確保焊接工作的 度及品質(zhì)。
考取國際焊工證的作用:
1.掌握應(yīng)用于不同行業(yè)的焊接操作技巧,提高焊縫質(zhì)量及焊接效率。
⒉掌握扎實的焊接 理論用以指導(dǎo)并解決焊接缺陷問題,成為焊接領(lǐng)域的技術(shù)性人才。
3.養(yǎng)成職業(yè)安全習慣及消防意識,使學(xué)員在實際生產(chǎn)中避免或盡量減少事故的發(fā)生。
