An entertaining romp through the hills and valleys (mostly valleys) of ultrasonic beam plotting and angles when dealing with curved surfaces. If you’re going to scan something “around the curve” and you don’t know what to do and maybe you’ve lost that old trigonometry textbook, don’t fret… I made you some tables.
The 2018 edition fo the Canadian code for structural welding, CSA W59 has been released. On the ultrasonics side (because that’s why you’re here, right?) it features the new Annex X for sensitivity calibration with a DAC/TCG for both conventional and manual phased array inspections.
CSA codes are notoriously humourless. I’m trying really hard to keep it that way (sigh).
The 2017 ASME code now requires the use of contoured wedges for pipe weld inspection. The wording in the code is a little obtuse (to say the least). This article attempts to explain what I think they were getting at. And if you dig down into the crumbs at the bottom of the box, you'll find a nifty table-o-graph that answers all your questions. Huzzah!
