Why these

Worth more than they cost.

Built to be used on site and at the desk, not skimmed once.

Written by an inspector

Prepared by Joel J, a mechanical engineer and certified welding inspector, from what is checked on real sites.

Drawn, not described

Hundreds of original diagrams show what each method, gauge and imperfection looks like.

Explained answers

Every practice question comes with the reason, so you learn the principle, not the letter.
