Sample NSSCO Metalwork and Welding 6188 Practice Questions

Try these sample questions to test your NSSCO Metalwork and Welding 6188 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In the NSSCO Metalwork and Welding syllabus, NOSA refers to the:
A.National Occupational Safety Association
B.Namibia Official Standards Authority
C.National Outdoor Sports Association
D.Namibian Oxygen Safety Agency
Explanation: NOSA stands for National Occupational Safety Association. Learners must apply NOSA safety standards in the workshop, covering hazards such as obstruction, sharp edges, PPE, machinery guards, gas leakage and firefighting.
2When arc welding, eyes and body must be protected mainly against:
A.Ultraviolet and infrared radiation from the arc
B.Only workshop fluorescent lighting
C.Cold air from the extractor fan
D.Magnetic fields from nearby radios
Explanation: The syllabus requires protection of eyes and body against radiation when welding. Arc welding produces intense UV and IR radiation that can cause arc eye and burns without proper helmets, goggles and clothing.
3Loose clothing and jewellery in a metalwork workshop are hazardous mainly because they can:
A.Catch in rotating machinery or hot work and cause injury
B.Improve grip on smooth tools
C.Reduce the need for earthing
D.Replace the need for eye protection
Explanation: NOSA-related objectives warn against loose clothing and jewellery. Loose items can snag in drills, grinders or rotating parts, or contact hot metal, causing serious injury.
4Inadequate guards over machinery primarily increase the risk of:
A.Contact with moving parts leading to cuts, entanglement or amputation
B.Higher gas cylinder pressure
C.Faster cooling of weld pools
D.Improved chip clearance only
Explanation: The syllabus lists inadequate guards over machinery as a NOSA safety concern. Guards keep hands, clothing and tools away from belts, wheels and cutters.
5Portable electrical equipment in the workshop should be:
A.Properly earthed and used with damaged leads avoided
B.Used without earthing if the plug looks new
C.Operated barefoot to improve earth contact
D.Plugged into gas cylinder valves for power
Explanation: Syllabus safety objectives include earthing of electrical equipment and safe use of portable electrical equipment. Sound insulation, earthing and undamaged cables reduce electric-shock risk.
6Gas leakage in a welding workshop should be checked using:
A.An approved leak-detection method such as soapy water on joints — never an open flame
B.A lit match held near fittings to find the leak quickly
C.Compressed air blown into the acetylene hose only
D.Igniting the room air to see if it burns
Explanation: Oxy-acetylene safety includes testing for gas leaks. Leaks are found with soapy water or approved detectors; using a flame can ignite escaping gas and cause fire or explosion.
7Misuse of compressed air in the workshop is unsafe because it can:
A.Inject air into the body, blow debris into eyes, or damage equipment
B.Only cool tools and never cause injury
C.Replace the need for flashback arrestors
D.Neutralise acetylene automatically
Explanation: The syllabus lists misuse of gases such as compressed air among NOSA hazards. Directed compressed air can force particles into eyes or skin and cause serious injury.
8The ABC of first aid application stands for:
A.Airway, Breathing, Circulation
B.Acetylene, Brazing, Cutting
C.Anvil, Bench, Clamp
D.Arc, Bead, Crater
Explanation: The syllabus requires describing basic first aid including the ABC of first aid: Airway, Breathing and Circulation. This prioritises life-threatening breathing and circulatory problems.
9When treating bleeding wounds, the syllabus emphasises doing so:
A.With HIV and AIDS transmission risk in mind, using barrier precautions
B.Without washing hands so the wound stays 'natural'
C.By sucking the wound to remove dirt
D.By ignoring gloves because metalwork blood is sterile
Explanation: Specific objectives include treatment of bleeding wounds with HIV and AIDS in mind. Rescuers should use gloves or barriers and avoid contact with blood.
10A learner who receives an electric shock should first be approached by:
A.Breaking contact safely (isolate power / use a non-conducting aid) then treating as needed
B.Pulling them by bare hands while current may still flow
C.Pouring water on them while still connected to live equipment
D.Ignoring the incident until welding finishes
Explanation: First-aid objectives include electric shock. Rescuers must not become a second victim: isolate power or use an insulated aid before touching the casualty, then support ABC as required.

About the NSSCO Metalwork and Welding 6188 Exam

NSSCO Metalwork and Welding (6188) is Namibia’s Ordinary Level senior secondary Metalwork and Welding qualification for Grades 10–11. The NIED syllabus covers workshop safety and first aid, measuring and hand/power tools, drawing communication, metals and heat treatment, sheet metalwork, oxy-acetylene and arc joining, temporary fasteners, and metal finishing, with strong emphasis on safe process knowledge and practical artefact production.

Assessment

Paper 1 Written (2 hours, 100 marks, 50%): Section A ten short-answer questions (30 marks); Section B seven structured questions (70 marks). Paper 2 Practical Examination (3 hours, 50 marks, 25%): centre-assessed practical skills, externally moderated by DNEA. Paper 3 Artefact and Portfolio (about four terms, 50 marks, 25%): DNEA-supplied project with A3/A4 folder, photographic evidence and made artefact; centre-marked with DNEA moderation. Overall assessment objectives weight knowledge with understanding about 30%, problem solving 17.5%, interpretation of data 17.5%, practical skills 35%.

Time Limit

Paper 1: 2 hours; Paper 2: 3 hours; Paper 3: artefact/portfolio across about four terms (commence Grade 10 second trimester; complete by Grade 11 second trimester)

NSSCO Metalwork and Welding 6188 Study Tips from Top Performers

1Work from the official NIED NSSCO Metalwork and Welding syllabus PDF — examiners mark to the specific objectives under each of the nine topics.
2Treat safety (NOSA, PPE, gas/electrical hazards) as non-negotiable before oxy-acetylene or arc process questions.
3For Paper 2 and Paper 3, practise planning, safe tool use, accuracy and evaluation — MCQs alone cannot replace workshop skill or artefact production.
4Learn metal properties and heat-treatment purposes (annealing, hardening, tempering, case hardening, normalising) with clear cause-and-effect wording.
5Use recent NSSCO examiners’ reports for Metalwork and Welding 6188 to target weak theory and coursework moderation issues.
