1On a standard welding symbol, information placed below the reference line applies to which side of the joint?

A.The arrow side of the joint

B.The other side of the joint

C.Both sides equally regardless of arrow

D.Only field welds, never shop welds

Explanation: In AWS/CSA welding symbol conventions used in North American fabrication, weld data below the reference line describes the arrow side. Data above the line describes the other side. Dimensions and other entries along the reference line are read left to right, independent of which way the arrow points.

2What does an open circle at the junction of the arrow and the reference line indicate on a welding symbol?

A.Field weld during erection

B.Weld all around the joint

C.Backgouge before welding

D.Consumable insert required

Explanation: The weld-all-around symbol is an open circle at the arrow/reference-line junction. It instructs that the weld continues around the entire joint periphery, common on tubular or closed-profile connections.

3A flag at the junction of the arrow and reference line on a welding symbol means the weld is to be made:

A.Only with SMAW electrodes

B.As a shop weld before shipment

C.In the field during erection

D.As a intermittent stitch weld

Explanation: The field-weld flag indicates the weld is completed at the erection site rather than in the fabrication shop. Older drawings sometimes used a filled circle for the same intent, but the flag is the current convention.

4For a fillet weld symbol, the weld size is normally placed:

A.To the right of the fillet weld symbol

B.Inside the triangle of the fillet symbol

C.Only in the drawing title block

D.To the left of the fillet weld symbol

Explanation: Fillet weld size (leg length) is shown to the left of the fillet symbol. Length and pitch, when used, appear to the right. Inspectors verify as-welded fillet size against these dimensions with gauges.

5On an intermittent fillet weld symbol, the numbers to the right of the fillet symbol typically represent:

A.Weld length and pitch (center-to-center spacing)

B.Root opening and included angle

C.Electrode diameter and amperage

D.Base-metal thickness only

Explanation: Intermittent fillet symbols show fillet size to the left and length and pitch to the right (for example, 50-150 meaning 50 mm long welds on 150 mm centers). Pitch is measured center-to-center of adjacent weld segments.

6Which joint type is formed when the edge of one member is placed on the surface of another member approximately at a right angle, resembling a letter T?

A.Butt joint

B.T-joint

C.Lap joint

D.Corner joint

Explanation: A T-joint places the edge of one member against the face of another, typically near 90°. Fillet welds commonly join T-joints; groove welds may be used when full penetration is required.

7Two plates joined edge-to-edge in the same plane form which basic joint type?

A.Lap joint

B.Edge joint

C.Butt joint

D.T-joint

Explanation: A butt joint places members approximately in the same plane with edges meeting. Groove weld preparations (square, V, bevel, U, J) are commonly applied to butt joints to achieve required penetration.

8In a single-bevel groove weld symbol, which member is typically prepared?

A.Always both members equally

B.Only the thicker member regardless of the symbol

C.Only the thinner member regardless of the symbol

D.Only the member indicated by the broken arrow (when used) or as shown by the bevel symbol orientation

Explanation: A bevel-groove symbol indicates preparation on one member. A broken arrow may clarify which member is bevelled. Inspectors verify that the prepared member matches the drawing before welding starts.

9Which statement about the vertical (perpendicular) line in a standard AWS bevel-groove or J-groove weld symbol is correct?

A.It is drawn on the left of the symbol as a drafting convention; the arrow (often broken) identifies which member is prepared

B.It always identifies the thicker member as the one that must be bevelled

C.It indicates mandatory post-weld heat treatment

D.It indicates the direction of welding travel

Explanation: On bevel and J groove symbols, the perpendicular stroke is placed on the left by drafting convention, regardless of joint orientation. Which member is chamfered or J-prepared is shown by the arrow (often with a break pointing to the prepared piece), not by treating the vertical stroke as an "unprepared member" indicator.

10A melt-through symbol (black semicircle opposite a groove weld symbol) indicates:

A.Only a tack weld is required

B.Complete joint penetration with visible root reinforcement on the opposite side

C.Peening of the weld face is mandatory

D.The weld must be ground flush

Explanation: The melt-through supplementary symbol indicates the intent for complete joint penetration with melt-through visible on the opposite side. Inspectors look for appropriate root reinforcement rather than incomplete penetration.

About the CWB Welding Inspector Level 1 Exam

CSA W178.2 Level 1 certifies visual welding inspectors who work under Level 2 or Level 3 supervision in Canada. The closed-book fundamentals exam emphasizes design/drawings/weld symbols (≈41%), welding processes and procedures (≈19%), quality control (≈16%), equipment and consumables (≈13%), visual inspection (≈10%), and NDT awareness (≈1%) per CWB Form 301 Appendix A. Candidates also complete a chosen code endorsement (for example CSA W47.1/W59), a short CSA W178.2 open-book paper, and a practical sample exam.

Assessment

Certification requires multiple sittings: (1) closed-book Basic Welding Inspection and Basic Welding Fundamentals — typically 75 multiple-choice questions (exemptible after an accepted CWB Level 1 training course); (2) open-book product-category code/standard endorsement — typically 45 multiple-choice; (3) open-book CSA W178.2 — typically 15 multiple-choice; (4) practical visual detection, identification, assessment and descriptive reporting of basic weld faults — 5 samples. All requirements must be finished within 2 years of application approval.

Time Limit

Closed-book fundamentals 2 hours; open-book code 2 hours; CSA W178.2 0.5 hour; practical/reporting 0.75 hour (CWB Form 301E/2026-5). Number of questions may vary from time to time.

Passing Score

70% minimum on each examination in a single sitting.

Exam Fee

Initial application fee CAD $548.00 + applicable tax (covers the Level 1 certification application path per Form 301 fee table). Open-book additional code endorsement CAD $97.50; rewrite per exam CAD $161.50; 3-year renewal / 6-year recertification fees CAD $325.00 (confirm current Form 301 schedule — fees subject to change). Course tuition is separate. (CWB Group (Canadian Welding Bureau))

CWB Welding Inspector Level 1 Study Tips from Top Performers

1Drill AWS/CSA-style welding symbols until arrow-side/other-side, size/length/pitch, field weld, and all-around become automatic — they are about 41% of the closed-book blueprint.

2Study from a current WPS/PQR pair and practice spotting essential-variable changes, preheat/interpass checks, and consumable storage rules for E7018-type electrodes.

3If you take an accepted CWB Level 1 course, confirm whether you receive the closed-book exemption, then focus remaining study on your chosen open-book code (for example CSA W47.1/W59) and practical fault identification.

Frequently Asked Questions

What exams are required for CWB CSA W178.2 Level 1 certification?

Typically a closed-book fundamentals exam (about 75 multiple-choice questions, 2 hours — often exempt after an accepted CWB Level 1 course), an open-book code/standard endorsement (about 45 questions, 2 hours), an open-book CSA W178.2 exam (about 15 questions, 0.5 hour), and a practical visual sample exam (5 samples, 0.75 hour). You must score at least 70% on each.

How much does CWB Level 1 welding inspector certification cost?

CWB Form 301E (June 2026 fee table) lists a Level 1 initial application fee of CAD $548.00 plus tax. Extra open-book code endorsements are CAD $97.50; rewrites are CAD $161.50 per exam. Optional CWB Level 1 training courses (often around CAD $2,100 plus textbook) are separate from the certification application fee. Confirm the current Form 301 schedule before paying.

What topics dominate the Level 1 closed-book exam?

Per Form 301 Appendix A, approximate closed-book weights are Design, Drawings and Weld Symbols 41%; Welding Processes and Procedures 19%; Quality Control 16%; Welding Equipment and Consumables 13%; Visual Inspection 10%; and NDT 1%.

Can a Level 1 inspector work independently?

No. CSA W178.2 Level 1 welding inspectors perform visual welding inspection under the supervision of a Level 2 or Level 3 inspector. Independent inspection is associated with Level 2 and above.
