NSSCO Metalwork and Welding 6188 exam-day guide
NSSCO Metalwork and Welding 6188 · Prepare for the day ahead.
Your checklist
Admission/entry letter and national ID
Bring the printed exam entry confirmation and the identity document the exam centre expects. Confirm the exact acceptable documents with your school or the examining body before the day - do not assume a school card will be accepted.
Workshop overalls or shop coat
Clean, cotton-based overalls that cover arms and legs. No synthetic-only clothing near arc welding or hot metal, and no loose sleeves or torn hems that can catch on rotating or sharp edges.
Safety boots and eye protection
Closed steel-toe boots and impact-rated goggles or spectacles. Confirm with the provider whether boots are compulsory or whether leather shoes are accepted at your centre.
Welding helmet with spare lens
Hand shield or head helmet with a correct shade filter for the current used, plus a spare filter plate and cover lens. Check the headgear adjustment and the condition of the filter before packing.
Leather gloves, apron and cap
Gauntlet gloves free of holes, a leather apron for welding and chipping, and a close-fitting cap or hair covering. Long hair tied back and no loose jewellery.
Personal hand-tool kit as listed by the provider
Steel rule, scriber, try square, centre punch, dividers, hacksaw with spare blades, files (flat, half-round, round), hammer and chipping hammer. Mark your tools so they can be identified and counted at the end.
Measuring and marking instruments
Vernier caliper, protractor or angle gauge, and a micrometer if the centre permits it. Confirm with the provider which measuring instruments you are allowed to use during the assessment.
Cleaning and finishing materials
Wire brush, emery cloth or abrasive paper, and a clean rag. These are usually needed for weld cleaning and final presentation and are sometimes not supplied at the bench.
Pencil, eraser and a small notebook
For working out allowances, marking dimensions and recording your sequence of operations. Confirm whether rough paper and calculators are permitted in the workshop.
Electrodes, filler rods and flux
Check whether consumables and stock material are issued at the venue or must be brought. This varies - confirm with the provider rather than buying consumables you may not need.
Water bottle and personal medication
Welding and filing are hot, physical work. Bring water if the centre allows it, and tell the invigilator in advance about any medical condition or medication you may need during the session.
Confirmed venue, time and travel plan
Know which workshop you are writing in, the reporting time and how you will get there. Aim to arrive well before the reporting time so you can change into PPE without rushing.
Plan the day
Re-read the practical instructions and the provider's tool list from your school. Check every item on the list, replace worn hacksaw blades and damaged file handles, and make sure your helmet filter and gloves are undamaged. Spend the remaining workshop time on the operations the task is likely to test - marking out, square filing, drilling, tapping, and running straight beads on scrap plate - rather than starting new projects. Confirm the reporting time, venue and what material and consumables are supplied.
Pack the toolbox in the order you will use it and count the tools against the list. Lay out overalls, boots, gloves, helmet and eye protection together so nothing is left behind. Do a final check that your name is marked on tools and that you have the entry letter and ID. Eat properly, avoid late-night practice, and sleep - fatigue causes more lost marks in a workshop than lack of skill.
Eat a proper meal and arrive early enough to change and set up. Report to the invigilator with your ID and entry letter, listen to the safety briefing, and note where the fire equipment, first-aid point and emergency stop are. Lay out your tools on the bench, check the condition of the machine you are assigned, and report any fault - a damaged cable, faulty guard, bad earth clamp or slipping chuck - before you start, not after.
Read the whole task and any drawing before touching material. Identify every dimension, tolerance, surface finish requirement and joint type. Write a short sequence of operations and a rough time budget - marking out, cutting, filing and fitting, drilling or tapping, welding or joining, cleaning, inspection. Check that the stock you have been issued matches the size the drawing assumes before you cut anything.
Work to your plan but leave 15–20 minutes at the end for cleaning, inspection and final measurement. Mark out from a single datum and double-check before cutting; a few millimetres lost at the marking-out stage cannot be recovered later. Keep the bench clear, put files back on the rack, and never leave a hot workpiece or an unguarded machine unattended. If you finish a stage early, use the time to check squareness and dimensions rather than to start a new feature.
Clean the workpiece, remove slag and spatter, deburr sharp edges, and present it as the drawing requires. Measure your final dimensions and record them if the paper asks for it. Clean the bench and machine, return borrowed tools, sweep up swarf, and have your own tools counted out by the invigilator before you leave the workshop.
Rules to check
Carry your ID and entry document for the whole session and place them where the invigilator can check them. Confirm with the provider which documents are acceptable and what happens if one is missing - do not rely on a verbal assurance from a classmate.
Eye protection and the required PPE must be worn for all cutting, chipping, grinding and welding operations. Ask the invigilator to clarify the centre's policy on removing PPE at a specific machine, and never remove eye protection while anyone nearby is grinding or chipping.
Follow the invigilator's instructions and the workshop safety rules exactly. If a machine, guard, cable, electrode holder or gas set is faulty, stop and report it - do not attempt your own repair, and do not swap equipment without permission.
Work only on your own task. Do not borrow tools, materials or consumables from another candidate and do not assist or receive assistance with marking out, fitting or welding; unsupervised collaboration is treated as misconduct.
Ask the invigilator before leaving the workshop for any reason. The rules on toilet breaks, rest breaks and whether lost time is made up vary between centres - confirm them at the start of the session rather than assuming you will be given extra time.
Switch mobile phones off and store them out of reach unless the provider has explicitly allowed a calculator or device. Unauthorised devices or notes at the bench may be treated as cheating.
Your mark is normally awarded for dimensional accuracy against the drawing tolerances, workmanship and finish, quality of joints and welds, safe working practice, and completion within the time allowed. Ask the invigilator to confirm how the marks are divided for your paper.
Before you leave, clean your bench and machine, account for all tools issued to you, and dispose of hot metal and swarf in the containers provided. Housekeeping and safe shut-down are commonly assessed and a dirty, unaccounted-for bench can cost marks.
