1According to BS EN ISO 14731 (Welding coordination — Tasks and responsibilities), what level of technical knowledge is required for a Welding Coordinator assigned 'Comprehensive' technical knowledge?

A.Basic technical knowledge covering simple welded structures only

B.Specific technical knowledge restricted to carbon steels under 20 mm thickness

C.Full technical knowledge where comprehensive technical knowledge is required for the assigned welding activities

D.Elementary knowledge suitable only for non-structural tack welding supervision

Explanation: BS EN ISO 14731 defines three levels of technical knowledge for welding coordination personnel: Comprehensive (full technical knowledge), Specific (specific technical knowledge for limited range of materials/processes), and Basic (basic technical knowledge for simple structures). Personnel with comprehensive knowledge are qualified to plan, execute, supervise, and test all complex welding operations without technical restriction within their scope.

2Under BS EN ISO 3834 (Quality requirements for fusion welding of metallic materials), which part specifies 'Comprehensive quality requirements'?

A.BS EN ISO 3834-1

B.BS EN ISO 3834-2

C.BS EN ISO 3834-3

D.BS EN ISO 3834-4

Explanation: ISO 3834 is structured into five parts: Part 1 gives criteria for selection; Part 2 specifies 'Comprehensive quality requirements' (highest level); Part 3 specifies 'Standard quality requirements'; Part 4 specifies 'Elementary quality requirements'; and Part 5 lists normative document references required for compliance.

3During contract review under BS EN ISO 3834-2, which of the following is a primary duty of the Welding Supervisor/Coordinator?

A.Determining the commercial profit margin of the fabricated structure

B.Verifying that parent materials, consumables, and WPS capability match contract requirements

C.Issuing commercial invoices directly to the purchasing client

D.Authorizing design stress changes without consulting the structural engineer

Explanation: Contract review under ISO 3834-2 requires the welding coordination team to verify technical feasibility before production begins. This includes ensuring parent material specifications, filler metals, WPS approvals, welder qualifications, NDT equipment, and workshop facilities meet all client contract requirements.

4Which document must a Welding Supervisor confirm is qualified and available on the shop floor before production welding begins on a structural joint?

A.Welding Procedure Qualification Record (WPQR) only

B.Preliminary Welding Procedure Specification (pWPS)

C.Approved Welding Procedure Specification (WPS)

D.Mill Test Certificate (MTC) Type 2.1

Explanation: Production welders must follow a qualified and approved Welding Procedure Specification (WPS) issued for production work. A pWPS is only a draft used prior to WPQR testing, and a WPQR is the backing lab test record retained by quality management. Welders must weld directly to an approved WPS.

5What is the primary objective of storing basic MMA (SMAW) electrodes in a holding oven at 100°C to 150°C after baking?

A.To prevent moisture re-absorption and hydrogen-induced cracking

B.To increase the melting rate of the core wire during welding

C.To anneal the flux coating and increase flexibility

D.To burn off volatile organic oils from the steel core wire

Explanation: Basic flux coatings (e.g. E7018) are hygroscopic and absorb atmospheric moisture, which dissociates into atomic hydrogen in the arc stream. Holding ovens (100°C–150°C) maintain electrodes dry after high-temperature baking (300°C–350°C), maintaining diffusible hydrogen levels below 5 ml/100g deposit metal (Scale D/E) to prevent Cold Cracking.

6Under ISO 14731, how do the core responsibilities of a Welding Supervisor differ from those of a Senior Welding Inspector?

A.The Supervisor manages production workflow, welder allocation, and process compliance, whereas the Inspector independently verifies compliance against acceptance standards

B.The Supervisor performs destructive lab testing, whereas the Inspector writes WPS documents

C.The Supervisor certifies NDT radiographs, whereas the Inspector manages shop-floor logistics

D.There is no functional distinction under ISO 14731; both roles are identical

Explanation: A Welding Supervisor focuses on operational management: allocating qualified welders, ensuring correct WPS usage, equipment setup, heat input control, and productivity. A Welding Inspector acts as an independent quality verification authority, evaluating completed joint preparations, monitoring operations, and assessing final welds against ISO 5817 acceptance criteria.

7According to BS EN IEC 60974-14, how frequently should calibration or validation of arc welding equipment meters (voltage and current display) be conducted under standard industrial conditions?

A.Every 5 years

B.Annually (every 12 months)

C.Prior to every single shift change

D.Only after a transformer coil failure

Explanation: BS EN IEC 60974-14 (and ISO 17662) specifies that arc welding power sources and instrumentation used for quality-critical fabrication should be validated/calibrated at least once every 12 months (annually), or after any major repair, modification, or physical damage.

8When a Non-Conformance Report (NCR) is raised for a weld defect exceeding ISO 5817 limits, what is the immediate first action required by the Welding Supervisor?

A.Grind out the entire weld length without recording the location

B.Quarantine/mark the affected item to prevent further unauthorized processing and log details

C.Re-weld directly over the defect using high current to melt out slag

D.Scrap the entire assembly immediately without evaluation

Explanation: Quality control procedures require immediate identification and segregation/quarantining of non-conforming items. Marking the affected area prevents further work until an approved concession, repair procedure, or disposition action is documented.

9How must parent material heat/cast numbers be handled when cutting a certified structural steel plate into smaller component parts?

A.Discard heat numbers once the master plate is cut

B.Transfer original heat numbers to all offcuts using approved low-stress stamping or durable marking before cutting

C.Paint all offcuts with yellow primer without written markings

D.Only re-stamp offcuts if the client's inspector is physically standing on the shop floor

Explanation: Material traceability requires that heat, cast, or batch numbers are transferred to all cut sub-components prior to sectioning. Hard stamping (using low-stress dot stamps) or approved durable paint pens ensures full material certificate (BS EN 10204 3.1) traceability throughout fabrication.

10According to BS EN 1011-1, under what ambient temperature condition should production welding generally be halted unless special preheating measures are applied?

A.Below +5°C (or 0°C depending on specification)

B.Below +20°C

C.Below +30°C

D.Only when ambient temperature drops below -40°C

Explanation: BS EN 1011-1 states that when ambient temperatures fall below +5°C (or below 0°C under specific carbon steel standards), preheating or warming the joint area is required to remove condensation/moisture and reduce rapid cooling rates that promote brittle martensite formation.
