Dry Film Thickness: One Spot Is Not the Area
A reading, a spot, and an area average are three different facts. One touch of a dry film gauge is not the thickness of an area. The count of spots, and the thickness that is allowed, live in the specification for the job.
What a Holiday Detector Is Looking For
A path through a coating that is not conductive, down to metal. The ground matters. A wet sponge and a high-voltage spark tester are different tools. No voltage is stated. This is not electrical training.
Visual Weld Discontinuities on a Practice Coupon
Name the shape you can see: undercut, overlap, porosity, a crack, high-low, an arc strike. Naming the shape is not the same job as accepting it. The sketches are original teaching drawings.
How to Write a Daily Inspection Report
Identity, revision, who did the work, the instrument and its check, what you found and where, the comparison you made, the open items, and your name. A slogan is not a report. Use the project form when you are on a job.
