Try these sample questions to review concepts for the SPM Kimpalan Arka dan Gas exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to the American Welding Society (AWS) definition used in the KSSM syllabus, welding is best defined as the process of joining two pieces of metal by...

A.heating them to a high temperature until they melt or fuse together, forming a weldment

B.gluing them together with an industrial epoxy adhesive

C.bolting them together with mechanical fasteners only

D.pressing them together at room temperature without any heat

Explanation: The AWS definition taught in KSSM Kimpalan Arka dan Gas describes welding as joining two pieces of metal by heating them to a high temperature until they melt or fuse together to form a weldment (sambungan kimpalan).

2Which of the four welding processes taught in this syllabus uses a non-consumable tungsten electrode that does not melt into the weld?

A.TIG welding (GTAW)

B.SMAW (stick welding)

C.MIG welding (GMAW)

D.Oxyacetylene welding (OAW)

Explanation: TIG (Tungsten Inert Gas / GTAW) welding uses a non-consumable tungsten electrode; filler metal, when needed, is added separately by hand.

3The 'fire triangle' used to explain how fires start in the welding workshop consists of which three elements?

A.Fuel, oxygen and heat

B.Fuel, water and oxygen

C.Heat, water and smoke

D.Oxygen, smoke and ash

Explanation: A fire needs fuel (bahan api), oxygen and heat to start and continue burning; removing any one of the three elements extinguishes the fire.

4Which type of fire extinguisher is generally suitable for putting out an electrical equipment fire in the welding workshop?

A.A carbon dioxide (CO2) type extinguisher

B.A water-type extinguisher

C.A bucket of sand only

D.A wet cloth soaked in water

Explanation: CO2 extinguishers do not conduct electricity and smother the fire by displacing oxygen, making them suitable for electrical fires and gas/liquid fires.

5A water-type fire extinguisher is generally NOT recommended for which type of fire in the welding workshop?

A.A fire involving live electrical equipment

B.A fire involving ordinary combustible waste such as paper and rags

C.A fire involving dry wooden pallets

D.A fire involving dry cardboard packaging

Explanation: Water conducts electricity, so a water-type extinguisher should not be used on fires involving live electrical equipment; a CO2 extinguisher is safer in that situation.

6Which piece of personal protective equipment (PPE) is essential specifically to protect a welder's eyes and face from arc flash and intense light during arc welding?

A.A welding helmet fitted with the correct filter shade lens

B.Clear safety spectacles with no tinted lens

C.A standard dust mask

D.Ear plugs

Explanation: A welding helmet with a correctly rated filter shade lens protects the eyes and face from arc flash, ultraviolet/infrared radiation and flying spatter during arc welding.

7Which of the following is classified as an example of 'human negligence' (kecuaian manusia) as a cause of workshop accidents?

A.Operating a machine without sufficient knowledge of its correct procedure

B.A workshop with poor lighting and ventilation

C.A machine that has a manufacturing defect from the factory

D.A power outage that stops all machines suddenly

Explanation: Operating equipment without adequate knowledge or without following standard operating procedure is classified under human negligence, one of the three main causes of workshop accidents.

8Why is systematic management of stock and low-value assets (Aset Bernilai Rendah / ABR) important in a welding workshop?

A.It helps control costs, avoid wastage and support accurate planning and purchasing decisions

B.It guarantees that every welding project will pass on the first attempt

C.It eliminates the need for any workplace safety procedures

D.It replaces the need for a teacher or supervisor in the workshop

Explanation: Good stock and low-value asset management helps control costs, prevent wastage, and supports planning, purchasing decisions and accurate record-keeping in the workshop.

9During basic CPR (cardiopulmonary resuscitation) on an unresponsive welding-shop casualty who is not breathing normally, what should the rescuer do FIRST regarding the airway?

A.Tilt the head back and lift the chin to open the airway before beginning compressions

B.Immediately begin chest compressions without checking the airway

C.Give the casualty a drink of water to help them swallow and recover

D.Wait at least 15 minutes before doing anything, in case the casualty wakes up on their own

Explanation: Basic CPR steps begin with opening the airway (tilting the head back and lifting the chin) before starting chest compressions, so air can pass freely once breaths or compressions are given.

10Which factor is identified in the syllabus as a source of environmental and health risk specifically arising from welding operations?

A.Fumes and gases released from the electrode coating and base metal during welding

B.The colour of the welding helmet used by the operator

C.The brand name printed on the welding machine

D.The number of chairs available in the workshop

Explanation: Welding releases fumes and gases from the electrode coating, shielding gas and base metal, which can pose health risks to workers and environmental risks if not properly ventilated and controlled.

SPM Kimpalan Arka dan Gas: Suggested Study Strategy

1Distinguish the four welding processes taught: SMAW (consumable flux-coated electrode struck as an arc), OAW (oxygen plus acetylene flame), MIG/GMAW (consumable wire electrode plus shielding gas), and TIG/GTAW (non-consumable tungsten electrode plus inert shielding gas).

2Memorise gas cylinder safety codes: the oxygen cylinder is black with a right-hand-thread valve and a blue/green hose; the acetylene cylinder is maroon/red with a left-hand-thread valve and a red hose, so hoses cannot be connected to the wrong gas by mistake.

3Learn the three oxyacetylene flames: carburizing (excess acetylene, feathery inner cone, used for braze welding/meloyang), neutral (balanced, used for most welding) and oxidizing (excess oxygen, hissing sound, sharp inner cone).

4Know the five weld joint types: butt (temu), lap (tindih/lekap), corner (penjuru), T-joint (kambi T), and edge (tepi) joints.

5Practise linking weld defects to causes: porosity from a dirty or damp surface, distortion from uneven or rapid cooling, incomplete fusion from too-low current or too-fast travel speed, and excess spatter from too-high current.

6Compare arc-welding position codes: 1G/1F is flat, 2G/2F is horizontal, 3G/3F is vertical and 4G/4F is overhead, where G marks groove (butt) joints and F marks fillet joints.

7Remember PPE for welding work: a welding helmet with the correct filter shade, leather apron and gauntlet gloves, safety boots and ear plugs, plus adequate workshop ventilation to clear welding fumes.

8Drill basic costing: production cost = material cost + labour cost + overhead cost, then apply a target profit margin, matching official sample coursework calculations.

9Remember that official Kertas 1 still requires Malay short-response writing and diagrams; use these English MCQs for concept speed, then practise past Malay papers and coursework procedures.
