22/11/2012В В· The thickness range of the WPS used for the welder qualification is irrelevant - a company may have 100 x WPSs and you cannot limit a welder solely to the WPS he qualified with.

Elder Original question: Test coupon is 11 mm thick = T when applying QW-451, second column GTAW deposit thickness is 4 mm = t1 when applying QW-451 Third column SMAW deposit thickness is 7 mm = t2 when applying QW-451 Third column Base metal thickness range qualified is вЂ¦
Base Metal Thickness Range: AWS D1.1 Welder Qualification Test Procedure Carbon Steel Plate Test (WQTP #2) (Revision 0) Page 3 Welding Notes: Once test weld is placed in the 3G or 4G position, the test weld shall not be removed until completion of the weld At the completion of the test welds, the coupons shall be visually examined in accordance with AWS D1.1, Clause 188.8.131.52 вЂVisual. Weld Qualification Welding is an engineering process that joins components or parts of similar or dissimilar compatible materials. This is often done by melting the joining interfaces of the objects and adding a filler material to form a pool of molten material which forms a permanent joint after solidification..
“FORM QW-484B SUGGESTED FORMAT B FOR WELDING ASME”.
The thickness limit only applies to the deposited weld metal thickness not the plate thickness and any groove weld approves all fillet weld sizes. For t greater than 12.5mm there is no restriction on the size that can be welded (Providing the test weld deposit contains at least 3 layers of weld)..

The test qualifies the welder to weld fillets or grooves of unlimited thickness in the process the welder used to weld the joint. The completed joint is visually inspected and specimens are destructively tested by вЂ¦ Welder Performance Qualification Test (WPQT) More than one PQR may be required to fully support the WPS (e.g., thickness range) Welder qualification tests should be designed to not exceed the limits of the WPS but do not need to meet all of the limits of the WPS . AWS B2.1 . Specification for Welding Procedure and Performance Qualification. Base metals categorized in M number format
qualification test limits, and these limits are very generous. By this table, a welder who successfully passes a groove weld qualification test is qualified to make fillet welds on all The previous note said that the weld metal thickness вЂњtвЂќ that one used to determine the thickness of weld metal qualified was based on the individual thickness of weld metal deposited by each welder, by each process and by each filler metal F-Number. QW-306 has always been broader; it requires one to considered individually each welder or welding operator, each welding process and whenever
