The SAIW Welding & Fabrication Inspector Level 2 course prepares welding inspectors to IIW IWI Standard level after completing Level 1, with a 5-week programme covering construction and design, materials technology, NDT, heat treatment, QA/QC, and procedure qualification. Candidates sit two three-hour theory papers (Technology and Inspection modules) and one five-hour practical examination; 2026 course fees are R52 152 (corporate member) or R56 286 (non-corporate) including VAT and initial exams. Graduates meeting IIW access conditions — IWI-Basic held, age 20+, and two years inspection experience — receive the internationally recognised IWI-S diploma. This free prep includes 100 practice questions with explanations and an AI tutor.

1In welded joint design, a full penetration butt weld is primarily intended to:
A.Transmit load through the full cross-section of the joint
B.Eliminate the need for any inspection
C.Avoid preheat in all materials
D.Replace the need for filler metal entirely
Explanation: Full penetration butt welds are designed so fusion extends through the entire joint thickness, allowing the weld to carry structural loads across the full section. Construction and design is a core Week 1 module in the SAIW Level 2 / IIW IWI-S syllabus.
2Which welded joint type is most commonly used where members meet at approximately 90° and one component is welded to the surface of another?
A.Fillet weld
B.Butt weld
C.Edge weld
D.Plug weld only
Explanation: Fillet welds join surfaces at angles (typically T-joints and lap joints) without requiring groove preparation through the full thickness. Inspectors at Level 2 must interpret fillet weld symbols and size requirements on fabrication drawings.
3Fatigue performance of a welded structure is most adversely affected by:
A.Geometric stress concentrators such as weld toe undercut and lack of fusion at toes
B.Use of approved WPS parameters alone
C.Painting after fabrication only
D.Mill test certificates on parent plate
Explanation: Fatigue cracks initiate at stress concentrators — weld toes, undercut, toe angle, and discontinuities. Level 2 construction and design covers how joint geometry and weld profile influence cyclic loading life.
4A single-V groove butt weld preparation is typically selected when:
A.Access permits welding from one side and controlled root quality is achievable
B.Both sides of the joint are always freely accessible for back-gouging without exception
C.No filler metal is permitted by the construction code
D.The joint is always classified as a fillet weld
Explanation: Single-V preparations bevel one member to allow penetration from one side, often with backing or controlled root procedures. Inspectors verify that the preparation matches the qualified WPS and drawing requirements.
5In pressure-vessel construction referencing ASME Section VIII principles taught at SAIW Level 2, welded categories define:
A.The type and extent of joint examination required for different joint locations
B.Only the paint colour for external surfaces
C.The welder's hourly wage rate
D.Transport restrictions for completed vessels
Explanation: Joint categories (e.g., Category A, B, C, D in ASME VIII) link joint location to required NDE extent and acceptance criteria. Level 2 construction and design connects code categories to inspection planning.
6Distortion control during fabrication is best addressed by:
A.Balanced welding sequences, tack spacing, and fixturing planned in the fabrication procedure
B.Ignoring interpass temperature to speed production
C.Removing all stiffeners before welding is complete
D.Welding only in the vertical-up position regardless of WPS
Explanation: Balanced sequences, adequate tacking, and restraint strategy limit angular and longitudinal distortion. Fabrication applications engineering in Week 4 addresses practical distortion management alongside design tolerances.
7A backing strip or backing ring in groove welding primarily:
A.Supports the first weld pass and contains molten metal at the root
B.Eliminates the need for qualified welders
C.Replaces final visual inspection
D.Guarantees immunity from hydrogen cracking in all steels
Explanation: Backing retains and shapes the root bead when welding from one side. Inspectors check whether backing is temporary or permanent per the WPS and whether it is removed if prohibited by the application standard.
8Weld symbol supplementary information such as weld contour and finish is placed on the:
A.Tail of the welding symbol
B.Company letterhead only
C.NDT technician's personal logbook
D.Shipping manifest
Explanation: Per ISO 2553 / AWS A2.4 conventions taught in inspector training, the tail carries supplementary data — process, NDT requirements, contour (flush/ convex), and special instructions. Level 2 inspectors must read complete symbol sets on drawings.
9Lamellar tearing susceptibility in thick restrained T-joints is most associated with:
A.Non-metallic inclusions in through-thickness (Z-direction) stressed plate
B.Excessive shielding gas flow on stainless steel only
C.Using GTAW exclusively on thin sheet
D.Painting before welding
Explanation: Lamellar tearing arises from delamination along inclusion bands when through-thickness strain is imposed, common in thick restrained T-joints. Materials Technology II covers parent-metal properties and joint design mitigation (e.g., buttering, joint orientation).
10A partial penetration groove weld is correctly described as:
A.Fusion penetration less than the full thickness of the joint, by design
B.A weld that always lacks sidewall fusion
C.A fillet weld with zero leg length
D.A weld that never requires a WPS
Explanation: Partial penetration joints are deliberately designed not to fuse the full thickness; the effective throat must be calculated and qualified. Inspectors distinguish intentional partial penetration from rejectable lack of penetration defects.
