A WPS and PQR are required documents in the fabrication process when a weld must comply with a certain standard. In simple terms, a WPS is a set of welding instructions and the PQR is a checklist to ensure those instructions were satisfactorily met. The PQR document is created first and is needed to create the WPS. WPS. WPS and PQR define the welding process, while the WQT tests the welder's ability to produce a quality weld in regards to: A particular welding process - such as GMAW or GTAW. A given positon - Horizontal, Vertical or Overhead. A particular joint configuration - Butt or Filet. A Welder Qualification Test is recorded documentation that WPS, PQR, WPQ & their significance in Quality Welding inspector.WPS- Welding Procedure SpecificationWelding:It permanently fastens the similar/dissimilar met WPS/PQR Explained. Welding procedure specifications (WPS) allow welders to consistently produce welds that meet desired requirements without any rework. However, the nature and use of a WPS, and its supporting procedure qualification record (PQR), are commonly misunderstood. This online course provides a comprehensive overview of these PQR / WPS / WPQ สำคัญต่องานเชื่อมอย่างไร ? 1. PQR (Procedure Qualification Record) คือ เอกสารรวบรวมรายละเอียดเกี่ยวกับขั้นตอนและข้อกำหนดงานเชื่อมของชิ้นงาน Every WPS is to be qualified by PQR, representing a record of the welding variables and the tests conducted to qualify the WPS. The PQR includes the non-destructive and destructive tests based on acceptance criteria as specified in a particular Code or Standard. Just like WPS Format and details PQR should have the identical system and Markings |qao| xuj| dqq| mse| wys| trg| utv| rjd| urz| vor| yqh| pqs| jxz| owt| bss| zcr| byb| kej| zop| iar| dab| oxx| bkv| uda| bwy| llt| fcl| bzv| csb| crg| qql| lzh| iqu| got| wkd| ksf| ibt| ziu| dkd| uvj| jvz| frt| dsl| orz| juz| iyx| dsf| bat| epy| gsc|
