什么是焊接程序规范(WPS)
焊接工艺规范(WPS)是mal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements . The purpose of the document is to guide welders to the accepted procedures so that repeatable and trusted welding techniques are used. A WPS is developed for each material alloy and for each welding type used. Specific codes and/or engineering societies are often the driving force behind the development of a company’s WPS. A WPS is supported by a Procedure Qualification Record (PQR or WPQR). A PQR is a record of a test weld performed and tested (more rigorously) to ensure that the procedure will produce a good weld. Individual welders are certified with a qualification test documented in a Welder Qualification Test Record (WQTR) that shows they have the understanding and demonstrated ability to work within the specified WPS.
根据这一点美国焊接学会(AWS),WPS详细规定了特定应用所需的焊接变量,以确保受训练的焊工的可重复性。AWS将PQR定义为焊接变量的记录,用于产生可接受的测试焊接和在焊接上进行的测试结果,以限定焊接程序规范。对于钢结构(土木工程结构)AWS D1.1是一种广泛使用的标准。它指定了一个资格预审选项(第3章)或a资格选项(第4章),供焊接过程批准。
这美国机械工程师协会(ASME)类似地将WPS定义为书面文档,该文件提供给焊机或焊接操作员的方向,用于按照代码要求制作生产焊接.ASME还将焊接PQR定义为在测试优惠券焊接期间记录的变量记录。记录还包含测试标本的测试结果。

What is WPS :
“焊接程序规格是一种形式,包含焊接槽的细节,待采用的焊接方法,电极和/或焊接杆型和直径,电流,电压,焊接位置,焊接运行号码和根据其CODES相关项目标准编写的类似信息(ASME和/或en标准)。
WPS由制造商/子承包商编写,并在工作开始前受授权检验机构批准。“
它包含有足够的细节,以使任何能力的人能够应用信息并产生可接受的质量焊接。在WPS上指定的细节和对照水平取决于要焊接的关节的应用和临界性。
应在W.PS上录制的典型项目: -
- Procedure number
- 过程类型
- Consumable Size, Type and full Codification.
- 可消耗的烘焙要求,如果适用
- 母材级和规格。
- 厚度范围。
- 板材或管道,直径范围
- 焊接位置
- 关节贴合,制备,清洁,尺寸等。
- 背带,后退刨刨信息。
- Pre-Heat (Min Temp and Method)
- 如果需要的是接口(记录的最高温度)
- 焊接后热处理。如果需要(时间和温度)
- 焊接技术(编织,最大运行宽度等)
- Arc Energy Limits should be stated if impact tests are required or if the material being welded is sensitive to heat input.
需要包括联合配置的草图,其应包括焊接制剂的基本尺寸。
