焊机的性能 & 焊接程序鉴定- WPQ, WPQR， & WPS

A WPQR is a company-specific qualification that proves that the holding company possesses the technical welding knowledge necessary to perform metal joining work. 一般, a new welding procedure qualification record is required each time a welding procedure is introduced. 

获得资格, an independent specialist must observe the new procedure being used on a sample welding plate or pipe. im体育APP's experienced welding coordinators can support you in the process of creating welding procedure 和 are also authorized to act as independent specialists. 

Once the sample welding plate or pipe has been welded, 它被加工成测试样品, which can then be passed to the im体育APP 实验室 for destructive 和 非破坏性测试. im体育APP then presents the results of these tests in a certificate (the WPQR) which provides a practical assessment of the welding method description.  All of this testing is conducted under ISO 17025 certification.

A WQC is a test certificate that shows whether a welder is skilled in welding to the specifications of a particular st和ard. im体育APP welding specialists can certify the welder through destructive 和 non-destructive tests to determine whether the welder is capable of producing a good weld quality using the welding processes, 材料, 以及规定的程序. 

A welder who has performed a test for a 焊接工艺评定记录(WPQR) automatically qualifies as a welder. If a good result is achieved, the welder receives an individual test certificate — the WQC.

In preparing new weld procedures to satisfy project requirements, our welding services offer expertise in 回顾 client specifications against fabrication requirements 和 preparing pWPS, 和 propose an interpretation of the testing 和 acceptance criteria. 跟踪客户的评论和意见, adjustments can be incorporated into the final version, 和 instructions issued for the welder 和 inspector once these have been agreed by all relevant parties.
