Hi, does anybody know how ISO weld qualification standards treat plug/slot welds? They are not mentioned in ISO 15614 and logically you can argue that a fillet/lap joint procedure should cover plug weld - is that correct? Thanks

Thanks, I guess our version of the standard is quite old and that was added recently

Hi, I'm writing my first PQR/WPS and have a question regarding the interpretation of ISO 15614. The standard states that butt weld on pipe with OD>25 covers all diameters > 0.5D. Does this mean that it covers butt weld on plate with implied diameter of infinity? Thanks

Hi, I'm fairly new to FEA and I'm trying to simulate pressurised tube T-Joint. I'm getting significant stress at the inner intersection. I tried increasing the fillet radius, adding reinforcement and ribs, but the stress at that point is not reduced. [image] Can I interpret that the part will...

Hi, I'm using O-rings for the first time & my worry is that the bore diameter is very close to the ring OD, but the compression seems to be OK. I'd appreciate if somebody with experience in those calculations can confirm if that is correct. It's a piston type seal, 100 bar, NBR O-ring. O-Ring...
