3、elding. The WPS shall be approved by the Technology Dept. Manager.焊接工程师应根据设计图纸，并为受压元件焊缝以及附件与受压件相焊的焊缝编制WPS。施焊前，WPS应经评定并有PQR（焊接工艺评定记录）支持。WPS应由技术部部长批准。7.1.2 All of the essential variables, nonessential variables and supplementary essential variables (if required) shall be documented in the WPS and meet

4、 the requirements of ASME Code .所有的重要变素、非重要变素及附加重要变素（如要求的话）应在WPS中予以说明，并符合ASME 规范的要求。7.1.3 WPS shall be re-qualified when changes are made in essential or supplementary essential variables (if required). Changes in nonessential variables may not require requalification of WPS. In order to incorporate

5、 such changes, the WPS shall be revised by correcting the original WPS and signature or by issue new WPS with new revision. 当重要变素与附加重要变素（如要求的话）有变化时，WPS须重新评定。非重要变素的变化可以不要求重新评定。为使WPS涵盖此变化，可以修改原来的WPS并签名或发行新的WPS（新的修订号）。7.1.4 The qualified WPS shall be issued to the work area and be made available to the

6、 welder for using.经评定的WPS应发放到工作区域，以便焊工查阅。7.1.5 The Welding Engineer shall prepare PQR to support the WPS. He shall provide test coupon and instruct welder how to carry out and supervise welding on the test coupon. Welding data used during the test as well as the mechanical test results shall be reco

7、rded on the PQR in accordance with ASME Code Section IX.焊接工程师须编制PQR以支持WPS，并提供试件，指导焊工如何在试件上焊接，并监督在试件上焊接。试验中的焊接参数及其机械性能试验结果应按照ASME规范第卷的要求记录在PQR中。The Welding Engineer shall witness welding of test coupon and mechanical test of specimen to verify the welding data and test results. The PQR shall be certi

8、fied by the Technology Dept. Manager.焊接工程师须见证试件的焊接与机械性能试验，以核实焊接参数与试验结果。PQR须由技术部部长确认。Additional data can be incorporated into a PQR as addendum at a later date provided the information is substantiated as having been part of the original qualification condition by the lab record or similar data. In t

9、his case, the addendum shall be recertified by the Technology Dept. Manager.如果附加数据可由试验记录或类似的数据证明为原始评定条件下的一个部分，则可在以后合并到PQR中。此时，附加数据须由技术部部长重新确认。7.1.6 The AI has right at any time to call for and witness test of the welding procedure.AI有权在任何时间要求和见证焊接工艺评定试验。7.2、Welder Performance Qualification焊工资格评定7.2.

10、1 All Welders performing activities to weld the Code Items must be qualified and certified according to the requirements of ASME Code Section IX and this Section.所有从事规范产品焊接工作的焊工必须根据ASME规范第卷及本章的要求进行技能评定和确认。7.2.2 The Welding Engineer shall instruct and supervise the Welders to weld test coupon for per

11、formance qualification according to a qualified WPS.焊接工程师应按照已评定的WPS指导和监督焊工焊接用于技能评定的试件。7.2.3 The Welding Engineer shall record the welding data used during welding of test coupon as well as mechanical or NDE test results on the WPQ. The Welding Engineer shall witness welding of test coupon and mechan

12、ical test (or NDE) and if necessary perform visual examination for no crack, complete joint penetration with complete fusion of weld metal and base metal to verify the welding data and test results.焊接工程师应在WPQ（焊工技能评定记录）中记录下试件焊接中运用的焊接参数及机械性能试验或NDE（无损检测）测试结果。焊接工程师应见证试件的焊接与机械性能试验（或NDE）并对试件做目视检验显示焊缝金属与母材

13、的全焊透与全熔透，无裂纹，以核实焊接参数和试验结果。7.2.4 WPQ shall be certified by the Welding Engineer. The “Qualified Welder List” (JSSN Form A7-01A, B) listing all currently qualified welders and their qualified range shall be prepared by the Welding Engineer and approved by the Technology Dept. Manager. Copies of the “Q

14、ualified Welder List” and WPQ shall be issued to the Workshop.WPQ应由焊接工程师确认。焊接工程师应编制“有资格焊工列表”（样表A7-01A、B），列出全部有资格的焊工和他们的资格范围，经技术部部长批准后印发给各车间。7.2.5 A Welder shall be re-qualified whenever a change is made in one or more of the essential variables for each welding process.每一焊接方法出现一个或多个重要变素改动时，必须对焊工重新进行
