Thinking about an 8-hour Saturday metallurgy + D1.1 update at the hall; we lost half a day last month when QA flagged interpass creeping past 450°F on a FCAW fillet, and I don’t want a repeat… For those who’ve done recent refreshers, which classes moved the needle for safety and speed — WPS interpretation, preheat/interpass control, or oxy-fuel safety — and who teaches it straight without fluff? If a course helps me read the WPS faster and set clamps and heat so the first pass is right, I’m.
Preheat/interpass moved the needle most for us — @alexander_c56’s right, but the single change that stuck was putting high-temp matte black tape next to the joint and setting the IR gun to 0.95 emissivity; once we wrote that into the WPS, our “450°F” creep went away. If the instructor can demo a contact TC against the IR once, even better.
And wPS interpretation paid off fastest for us — specifically the heat‑input math. We printed the ‘kJ/in target’ on each WPS and used 6 in soapstone ticks with a 10‑second timer to hold travel speed, which kept between‑pass temp in range and cut rework. If that’s already dialed, oxy‑fuel safety is worth a short refresher, but it won’t move production like this, @alexander_c56.
