1 Welding procedure specification Welding procedure specification (WPS) (WPS) 焊接工艺规范焊接工艺规范 Kevin Mo Kevin Mo 2 What is a WPS? 什么是焊接工艺规范(WPS)? What is a WPS? 什么是焊接工艺规范(WPS)? ?焊接工艺规范是为了制造符合规范要求的焊缝而提供指导的、经过评定合格的焊接工艺文件。它或其它文件可用于对焊工或焊机操作工提供指导,以保证符合规范要求。 A WPS is a written qualified welding procedure prepared to provide direction for making production welds to Code requirements. The WPS or other documents may be used to provide direction to the welder or welding operator to pliance with the Code requirements. 3 What is included by a WPS? WPS 的内容 What is included by a WPS? WPS 的内容?一份完整的 WPS 应当包含在 WPS 中所采用的、对每一种焊接方法而言的所有重要变素、非重要变素和当需要时的附加重要变素。样表见图1。焊接工艺规范其实就是规定某一焊接工艺的各种焊接变素。 pleted WPS shall describe all of the essential , nonessential , and, when required, supplementary essential variables for each welding process used in the WPS. For the sample, pls see the figure 1 . 4 Who take charge piling WPS? WPS 应该由谁制定? Who take charge piling WPS? WPS 应该由谁制定? ?每个制造者或承包者应按照焊接规范的规定编写合理的 WPS. 具体的说 WPS 是由代表厂家的焊接工程师编写的。 Each manufacturer and contractor shall prepare written Welding Procedure Specifications which are defined in corresponding welding code. 5 Availability of the WPS WPS 的可得性 Availability of the WPS WPS 的可得性?用于产品焊接的 WPS, 应当在制造现场便于获得,以供查考,并供授权检验师(AI) 检查。 A WPS used for Code production welding shall be available for reference and review by the Authorized Inspector (AI) at the fabrication site. 6 Authorized by AI Authorized by AI 授权检验师检查授权检验师检查 conducted by w conducted by w elder elder 焊工或焊接操作工焊工或焊接操作工根据根据 WPS WPS 进行生产 piled by welding engineer compiled by welding engineer according to qualified PQR according to qualified PQR 焊接工程师根据评定合格的工艺评定焊接工程师根据评定合格的工艺评定记录( 记录( PQR) PQR) 制定恰当的焊接工艺规范制定恰当的焊接工艺规范( ( WPS WPS ) ) supervised by AI supervised by AI 授权检验师检查授权检验师检查 Simple connection diagram Simple connection diagram WPS WPS 关系简图关系简图 Remarks: PQR is the qualified welding procedure procedure and test results record. 备注: PQR 是经过评定合格的焊接工艺数据及相关试验结果记录
