Can I develop an overlay WPS using QW-451.1? For instance it would be a GMAW P1 to P1 or P8 to P8. Is this possible without actually welding up a groove?

Hey guys, I will be qualifying a new WPS and WOPQ using a Boretech welder. So far I've done only plate WPS, and am a little unfamiliar with pipe and automated equipment. What is the best size diameter and thickness combo to qualify a WPS and WOPQ simultaneously with a Boretech? This will be done...

Can you qualify a WPS with a cast iron ie; A439 per ASME section IX? A WPS per ASME requires side bend tests which I don't think would pass. What are my options on qualifying this type of material?

If my WPS is qualified for 3/16" to 8" base metal thickness, can I do a repair weld on a base metal that's 14" thick? As long as I stay within the 8" limit? Or do I need a different WPS which would have 14" within the range?

What are the main differences between these two standards?

I searched the forums but could not find an answer. I'm qualifying a WPS with GMAW and FCAW on 1-1/2" P1 gr2 plate. GMAW root and FCAW filler and cover passes. Charpy testing will be at -50 F. This will be done per B31.3. From what I've read, it looks like I will need 3 specimens per set of...

Is anyone familiar with the ACCP/NDE Program?

Anyone know how I can go about finding a SCWI in Mexico?

The welder who performs the welding on a new procedure qualification, is the welder automatically qualified to weld on this new WPS? Can a WPQ be written for this welder, using these test results?

According to AWS D1.1 5.6 one of the paragraphs states "This preheat and all subsequent minimum interpass temperatures shall be maintained during the welding operation for a distance at least equal to the thickness of the thickest welded part( but not less than 3" in all directions from the...

Has anyone had any similar problems of cracking occurring at the HAZ of a P10H (or P8) T joint that is exposed to vibrations?

Hey fellas, If a WPS was qualified ie 2002, there should be no worries in regards to having to update any information on older WPS?

Hey fellas, I'm trying to qualify a new corrosion resistance overlay procedure per QW-453. I will be doing it on 1" plate in the 1G position with the GTAW process. My question is, will an individual whom is certified to weld with GTAW in 6G be able to use this procedure to weld in all...

Hey fellas, Does ASME or another company offer section IX seminars?

Hey fellas, If a welder is qualified using a P1 material base metal, is he also qualified to weld on P 45 material? If i'm reading QW-423.1 correctly he is. Thanks a bunch

I' trying to qualify a WPS per ASME section IX. This is going to be a Hard-facing overlay. Per QW-255.1, QW-403 asks for a P #, the base material is AISI 8620, which is NOT an ASME P #. Can I still qualify a WPS with PQR per ASME?

AWS D11.2 covers the qualification of welding cast irons and ASME section IX does not cover the qualification of welding cast irons? Is this correct?

In qualifying a welder, QW-302.1 refers to QW-452. In 452.1 it shows hat Visual examination can be used on the thicknesses shown. My questions are "do you need to perform tensile strength tests for a PQR?" and "Is a visual and bend test enough?"

Is anyone familiar with Powder welding of cast irons?

I'm fairly new to ASME IX, please bear with me. Is a weld procedure which states P1-P1 welding the same as P1 gr1- P1 gr1? If someone asks for a P1 gr2 weld procedure, does the P1 or P1 gr1 cover it? Thanks in advance
