Two acceptance routes, chosen long before anyone reads a radiograph. What the alternative route actually obliges you to produce, and why aggregate length governs more often than the worst single indication.
A working sheet with the formula, a worked check you can run on a real weld in two minutes, and the three production effects that put heat input outside its qualified range while every meter reading looks fine.
The visual acceptance criteria are not one table. The static/cyclic classification changes the limits, and getting it wrong invalidates the inspection record rather than one weld.
Nearly every B31.3 welding argument traces back to a fluid service category assigned much earlier. How that choice propagates into examination extent, and what closes it out under audit.
General tolerances decide fabrication cost more than almost anything else on the drawing. Which class to invoke, why the form class is the expensive one, and how to measure it without an argument.
The part the standard does not cover: which level to specify, who decides, and what evidence stands up in an audit six months later. Companion to the ISO 5817 acceptance criteria guide.
Every Therness thermal camera, weld-pool camera, HeatCore monitoring system and signal acquisition unit in one PDF, with specifications, integration options and a selection guide.
See how a Therness deployment pays back: scrap reduction, rework hours saved, and traceable evidence for ISO 17635/3834 audits — modeled on real welding production data.
An in-depth white paper covering the principles, techniques, and applications of Active Thermography for advanced material inspection and quality control — ideal alongside our industrial thermography service.

Why the bottom, shell, roof and nozzles are different NDE problems, what actually sets the required examination extent, and the joint map an auditor asks for.
The gap between what a welder's certificate says and whether it actually covers the job in front of them - essential variables, position coverage logic, and the misreadings that recur in audits.
The setup and evaluation checks that decide whether an MT result is trustworthy - because a clean result from a badly set up test looks exactly like a clean result from a properly set up one.
