Guide dossiers
Long-form sheets on the planning side of welding and fabrication: the procedure paperwork, the joint geometry, the processes and the hazards. Every dossier is written from the named public documents on its own source register — chiefly HSE and TWI publications — with original diagrams drawn as live, labelled SVG. No dossier carries an author persona, a sponsor or a verdict.
The guides cite their evidence inline and list it in a source register at the foot of each sheet; the full register, with publisher and retrieval dates kept distinct, lives on the sources sheet. For the calculators the guides cross-reference, see the tool register; for how every figure is produced, the methodology sheet.
