Fabrication & welding
From the 3D model to finished members: detailing, cutting, fitting, welding, inspection – and how to estimate scrap and welding consumables.
The steel fabrication process, step by step
How a structural member travels from the detailing model to the container: numbering, drawings, cutting, drilling, fit-up, welding, inspection, blasting, painting, packi…
Exporting a clean IFC from Tekla Structures: checklist
Numbering, marks, materials and file organisation that make the IFC import – and every report built on it – correct the first time.
Cutting optimisation and how to keep scrap below 3 %
Nesting plates and cutting bars is an optimisation problem. These are the levers that move scrap from 8–10 % down to a few per cent – and how yield is measured.
Welding basics for steel fabricators
Welding processes and their ISO 4063 numbers, fillet versus butt welds, throat and leg size, and the documents behind every weld: WPS, WPQR and welder qualification.
Estimating deposited metal and welding consumables
The arithmetic behind kg of wire per tonne of steel: weld cross-section, deposited metal, deposition efficiency and a worked example.
