焊接工藝評定及焊工資格評定服務(wù)
Welding Procedure Qualification and Welding Performance Qualification Services

焊接工藝評定：通過對執(zhí)行工藝焊制的試板進(jìn)行力學(xué)性能和其它性能的試驗，驗證工藝規(guī)程的正確性和合理性。
焊工資格評定：由需要進(jìn)行評定的焊工焊制符合規(guī)定的試板，對試板進(jìn)行無損檢測和力學(xué)性能試驗，來驗證焊工加工完好焊縫的能力。
SGS具備豐富的焊接工藝評定及焊工資格評定經(jīng)驗，行業(yè)涉及壓力容器、鋼結(jié)構(gòu)、閥門、中型機械、工程機械、石油機械等相關(guān)的焊接應(yīng)用領(lǐng)域，提供全套的焊接試板的檢測及焊接工藝、焊工資格的發(fā)證服務(wù)。
