Welding processes, WPS and NDT — what happens before an arc is struck
SMAW, GTAW, GMAW and the rest, explained by what they are good at. Then the paperwork that makes a weld legal — WPS, PQR and welder qualification — and how welds are inspected.
Non-destructive examination — choosing the method and reading the result
Why every NDE method is blind to something, what magnetic particle cannot do on stainless, why ultrasonics can miss a crack lying the wrong way, the difference between an indication and a defect, and why the examiner's qualification is part of the result.
Concrete and reinforcement — why the mix is the easy part
What concrete grade actually means, why the water-cement ratio decides almost everything, what cover is protecting, and why curing is the most neglected step on site.
