WPS WELDING PROCEDURE SPECIFICATION AWS D1.1 D1.3 B2.1 ASME IX DRF QW-484 EN 288 h.farghadani

WPS برای تهیه یک تعریف خوب و پایه ای برای طراحی عملیات جوشکاری و کنترل کیفیت هنگام جوشکاری مورد نیاز است. به جوشکاری به عنوان یک پروسه ویژه در میان استانداردها برای کیفیت سیستم توجه می شود. استانداردهای لازم برای کیفیت سیستم نیازمند این هستند که پروسه ها دقیقا منطبق با مشخصات دستورالعمل ها اجرا شوند. h.farghadani

WPS (مشخصات دستورالعمل جوشکاری) ممکن است که یک محدوده از ضخامتهای قطعاتی که باید به هم متصل شوند را پوشش دهد. همینطور محدوده ای از انواع فلزات پایه و حتی انواع فیلر متالها را پوشش دهد. بعضی از سازنده ها ممکن است که ترجیح دهند که برای آماده سازی دستورالعمل ساخت برای هر کار ویژه ای دستورالعمل جوشکاری را با اطلاعات اضافه تر تهیه کنند. همانند طرح تولید جزیی قطعات. h.farghadani

PQR PROCEDURE QUALIFICATION RECORD AWS D1.1 ASME IX DRF QW-483 EN 288 h.farghadani

WELDER The WPS and PQR refer to a specific weld process. A Welder QUALIFICATION: Performance Qualification (WPQ) is proves that an individual welder is capable of making a satisfactory weld using a specific WPS. The welder who actually welds the coupons for the PQR above is qualified in that procedure. If additional welders are to be qualified using a particular WPS, a process similar to but simpler than that above is used. h.farghadani
