SQA National 5 Practical Metalworking: the Fabrication area - sheet metalwork, joining, forming, finishing and the practical activity
A deep-dive SQA National 5 Practical Metalworking guide to the Fabrication area. Covers sheet metalwork (cutting, folding, seams), thermal joining (welding, brazing, soldering), mechanical joining and forming (rivets, fasteners, bending) and finishing, plus the practical activity and case study that assess the whole course.

What the Fabrication area actually demands
Fabrication is the area where separate pieces become a finished product. It teaches sheet metalwork, the joining methods (with heat and without), forming bar and rod, and finishing, and it leads into the practical activity that assesses the whole course. The skills here, with bench and machine work, are what you apply to make and finish your product. Each topic has its own dot-point page with worked questions; this guide ties them together.
Sheet metalwork
Sheet is marked out as a flat development with a bend allowance (metal stretches around a fold), cut with tin snips (short, curved cuts) or a guillotine (long, straight cuts), and folded on folding bars or a bending machine, usually to 90 degrees. Edges are folded over to remove the sharp raw edge and stiffen the part, and pieces can be joined by a folded seam.
Thermal joining
Heat joins metal three ways. Welding (MIG/arc) melts the parent metal so it fuses - the strongest joint. Brazing melts a brass/bronze filler into a heated joint without melting the parent metal - strong, slightly weaker. Soft soldering uses the lowest heat and a solder filler with flux for light or electrical work - the weakest. Flux cleans the metal so the filler flows and bonds.
Mechanical joining and forming
Without heat, rivets (solid, closed with a ball pein hammer; or pop rivets set with a rivet gun) make a permanent joint, while nuts, bolts and machine screws make a temporary joint that can be undone. Bar and rod are bent and formed over a former or in a vice, allowing for the metal stretching on the outside of the bend.
Finishing
The made product is deburred (sharp edges and burrs removed), the surface is cleaned and keyed with emery cloth, and a finish (paint over primer, lacquer, oil or plating) is applied. A finish gives protection (against corrosion and wear) and appearance; mild steel especially needs it because it is ferrous and rusts.
The practical activity
From 2025-26 there is no question paper: the course is assessed by one practical activity worth 80 marks (100%), in which you plan and make a metal product and complete a log book, plus a case study (10 marks) sampling knowledge of tools, materials, processes and safety. It is teacher-assessed and verified by Qualifications Scotland.
How the Fabrication area is examined
Through the practical activity and case study, the Fabrication area is sampled by:
- Describing processes step by step. How to cut, fold, join and finish accurately and safely.
- Choosing the right joint. Temporary or permanent, and the right thermal or mechanical method.
- Justifying a finish. Linking protection and appearance to the product and the metal.
