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 assure compliance with the Code requirements.

2

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。 The completed 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.

3

Who take charge of compiling 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.

4

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.

焊接工程师根据评定合格的工艺评定 记录(PQR)制定恰当的焊接工艺规范 (WPS)

Authorized by AI 授权检验师检查

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

conducted by welder 焊工或焊接操作工 根据WPS进行生产
