1Which standard specifies the qualification testing of welders for fusion welding of steels under European and International standards?

A.BS EN ISO 9606-1

B.BS EN ISO 15614-1

C.BS EN ISO 5817

D.BS EN ISO 17024

Explanation: BS EN ISO 9606-1 defines the qualification testing of welders for fusion welding of steels. ISO 15614-1 governs procedure qualification, ISO 5817 covers quality levels for imperfections, and ISO 17024 specifies requirements for personnel certification bodies.

2Under BS EN ISO 9606-1, what is the primary basis for welder qualification regarding filler metal designation?

A.Filler metal grouping (FM1 through FM6)

B.Exact brand name of the electrode manufacturer

C.Chemical composition match down to 0.01% trace elements

D.Electrode coating thickness classification

Explanation: BS EN ISO 9606-1 uses filler metal groups (FM1 to FM6) as the primary essential variable for welder qualification, allowing qualification on higher or equivalent FM groups to qualify lower FM groups as defined in the standard.

3Which filler metal group (FM) in BS EN ISO 9606-1 covers austenitic stainless steels and nickel alloys?

A.FM5 for austenitic stainless steels and FM6 for nickel alloys

B.FM1 for non-alloy and fine grain steels

C.FM2 for high-strength steels

D.FM3 for creep-resisting Cr-Mo steels

Explanation: In ISO 9606-1 Table 2, FM5 designates austenitic stainless steels and FM6 designates nickel and nickel alloys.

4Under ISO 9606-1, what is the default period of initial validity for a welder qualification certificate when verified every 6 months by the employer?

A.3 years (or 2 years depending on the chosen revalidation option)

B.10 years without any formal re-testing

C.6 months maximum with complete re-testing required twice per year

D.1 year fixed with no 6-month confirmation requirement

Explanation: ISO 9606-1 Clause 9.3 provides revalidation options: Option a requires revalidation every 3 years; Option b requires revalidation every 2 years; Option c requires revalidation every 6 months based on NDT testing. In all cases, confirmation of active welding every 6 months is required.

5Which standard specifies qualification testing of welders for fusion welding of aluminum and aluminum alloys?

A.BS EN ISO 9606-2

B.BS EN ISO 9606-1

C.BS EN ISO 15614-2

D.BS EN ISO 9606-4

Explanation: BS EN ISO 9606-2 specifies welder performance qualification testing specifically for aluminum and aluminum alloys.

6A welder qualifies by welding a butt joint on pipe with an outside diameter D = 50 mm. According to ISO 9606-1, what is the qualified diameter range?

A.0.5 D to 2 D (25 mm to 100 mm)

B.0.5 D to infinity (25 mm and above)

C.Exactly 50 mm only

D.10 mm to 50 mm

Explanation: Under ISO 9606-1 Table 10, for a test piece outside diameter D = 25 mm to 500 mm (or D >= 25 mm), the qualified range is >= 0.5 D (>= 25 mm). For D = 50 mm, the qualified range is 25 mm and above (>= 0.5 D).

7When a welder tests without backing (ss, nb) on a butt joint in sheet or pipe, what backing conditions are qualified under ISO 9606-1?

A.Single-side welding without backing (ss, nb), single-side with backing (ss, mb), and double-side welding (bs)

B.Single-side welding without backing (ss, nb) only

C.Double-side welding (bs) only

D.Single-side with ceramic backing only

Explanation: Welding single-sided without backing (ss, nb) is the most demanding root condition; therefore, under ISO 9606-1 Table 5, it qualifies single-side without backing (ss, nb), single-side with backing (ss, mb), and double-sided welding (bs).

8Under ISO 9606-1, if a welder completes a qualification test using MMA (Process 111) with basic electrodes (FM1), which electrode coatings are qualified?

A.Basic (B), rutile (R), acid (A), and cellulosic (C) electrodes within FM1

B.Basic (B) electrodes only

C.Cellulosic (C) electrodes only

D.Rutile (R) and Acid (A) electrodes only

Explanation: Under ISO 9606-1, qualifying with a basic electrode (B) in FM1 qualifies basic (B), rutile (R), acid (A), and cellulosic (C) electrodes within the qualified FM group, as basic electrodes demonstrate root and positional control capability.

9What is the mandatory minimum extent of testing required for a butt weld test piece under BS EN ISO 9606-1?

A.100% Visual examination (VT) plus volumetric testing (RT or UT) or bend tests (or bend/fracture tests)

B.Visual examination (VT) only

C.Radiographic testing (RT) only without visual examination

D.100% Magnetic particle testing (MT) only

Explanation: ISO 9606-1 requires 100% Visual Testing (VT) of the test piece prior to non-destructive testing (RT/UT) or destructive mechanical testing (bend tests or fracture tests). VT is always mandatory.

10For a fillet weld test piece under ISO 9606-1, what testing methods are required as standard?

A.Visual testing (VT) and fracture testing (or macroscopic examination)

B.Radiographic testing (RT) and tensile testing

C.Ultrasonic testing (UT) and side bend testing

D.Visual testing (VT) only without any mechanical testing

Explanation: Fillet weld test pieces under ISO 9606-1 require visual examination (VT) followed by fracture testing or macroscopic examination (at least two macro sections).

Frequently Asked Questions

What standards govern welder qualification under the CSWIP Welding Examiner scheme?

The primary standard is BS EN ISO 9606-1 (steels), alongside ISO 9606-2 through ISO 9606-5 for other metallic materials, and ISO 15614 for welding procedure qualification.

What is the role of a CSWIP Welding Examiner when witnessing a welder qualification test?

The examiner must verify material traceability, welding consumables, fit-up, WPS adherence, witness the entire welding process, stamp test pieces, and oversee required NDT and mechanical testing before signing the certificate.

How long is a CSWIP Welder Qualification Certificate valid under ISO 9606-1?

Under ISO 9606-1, an initial certificate is confirmed every 6 months by the employer/supervisor and requires revalidation every 2 years or 3 years depending on the revalidation option chosen (Option a, b, or c).
