Hi, I have a PQR for a fillet weld (only with macro). Can I use it for fillet welds on a pressure-containing component? Someone told me that a WPS for fillet welds for pressure containing components in production should be qualified with a butt weld. Regards, Patrick

Hi, Issue with classification ER70S-6 - SF 5.18 and A No.1 classification. ASME IX QW-442 says maximum 1.60 Mn and Si 1.0 for A No.1 ASME II C SFA 5:16 says Si 0.80-1.15 and Mn 1.40-1.85 (same as AWS 5.18) Why these 2 differences and what should I use? We have a 2.4 mm LNT 26 Lincoln filler...

Hello, can someone explain me what the meaning is of the text below? QW-410.47 is an essential for PAW hardface overlay and I have to mentioned this parameter in the WPS.What I do not understand is the rate of cooling temp from the fusing temp. and a change in fusing temp. QW-410.47 A change...

rodofgod, the supplier has determined the mechanical properties as welded with C02-Ar and not with O2. I think this is not correct.

Hi DekDee, yes I have, butt the used gas inthe PQR was Ar-C02-O2) I think oxygen is not allowed (O2 not approved). See attachement filler matwerial from supplier. Patrick

Hello, I have a PQR: Code AWS D1.1 Process: GMAW Material: S235JR Filler: Lincoln LNM 26 ER70S-6. AWS A5.18 Prescribed shielding gas: Ar or Ar-CO2 Gas used for PQR: Shielding gas: (M24 - Ar-CO2-O2) I think this is not allowed because: Applied shielding is not in accordance with...

Hi, What is de T range if: SMAW - Plate 15 mm - V-groove - P6 - PWHT and Impact tested in PQR Table QW-451.1 ASME IX said: Over 3/8 (10), but less than 3/4 (19) = 2T for T for base metal. Someone told me that T = 1.1 x T because Impact test and PWHT performed during the PQR Is that so and...

Dear people, Who can help me with the following? A PQR is made for a weld (see Annex 2) acc 15614-1. Tests are performed acc 15614-1 (Table 1) as T-connection by welding. The customer believes that testing the mechanical properties is required. Agree if this is a butt weld. But is this a butt...

I have a drawing (20 Years old) for an overlay with material X5CrNiMo 18-12.Is this AISI316??? I can not figure out the exact code. Google gives me several options but not the exact coding. As an example: Google says ..... X5CrNi18-12 but without Mo. Patrick

thanks for the comments!

Dear all, I have a GTAW semi-autom. WPS-PQR for overlay ER308L-ER309L on P1 Is it possible to create a new WPS for 309-316 on P1, based on the existing PQR without requalification? Thnx! Patrick

Dear people, what is the meaning of this symbol? Is this is a BW or FW? For me it seems that one side must be chamfered, welded and after that a fillet weld 10.5 mm And on the other side a fillet weld 14 mm Thnx, Patrick

Hello, Can a welders qualification be extended only based on a welding process, regardless material group, filler etc... Example: You have several Welding Procedures Specifications with different material groups, filler metal etc...but only with GTAW. A welder is welding one of the WPS'en...
