1A welding supervisor is assigning a welder to a groove-weld job on a new WPS. Which factor must be confirmed first?

A.That the welder is currently qualified for the process, position, and essential variables required by the job

B.That the welder has the highest hourly production rate in the shop

C.That the welder prefers the filler metal brand being used

D.That the welder worked overtime during the previous shift

Explanation: Qualification status must match the work being assigned before production starts. Productivity and preference matter later, but the supervisor cannot bypass qualification requirements.

2A schedule-critical weldment is ready, but the only available welder has not been qualified on the required process. What is the best supervisory decision?

A.Let the welder proceed if a senior welder watches closely

B.Delay production until a qualified welder is assigned or qualification is completed

C.Allow the welder to practice on the actual product first

D.Reduce inspection frequency so the job can move faster

Explanation: Supervisors must match personnel qualifications to the work instead of treating qualification as optional. Observation or reduced inspection does not replace a valid qualification record.

3A new crew starts on second shift after the first shift changed the weld sequence. What should the supervisor provide to reduce errors?

A.Only verbal instructions passed from one welder to another

B.A clear handoff with the current sequence, hold points, and any updated written instructions

C.A faster production target so the crew stays focused

D.Permission for each welder to choose any sequence that seems efficient

Explanation: Shift handoffs should communicate the current status of the job and any changed requirements. Clear written direction prevents the second shift from repeating work or violating the intended sequence.

4Why are welder qualification records important to a welding supervisor?

A.They show which employees prefer overtime assignments

B.They verify whether personnel are authorized for specific welding work

C.They replace the need for a WPS

D.They determine the price of filler metal orders

Explanation: Qualification records document the range of work a welder is permitted to perform. They do not replace technical instructions or purchasing data, but they are central to assigning people correctly.

5One welder has a rising repair rate on a recurring joint. What is the most effective first supervisory response?

A.Immediately suspend all welding in the shop

B.Review the welder’s technique, instructions, and setup to identify the cause before reassigning the work

C.Ignore the trend until final inspection rejects the product

D.Replace the WPS without checking the actual problem

Explanation: A supervisor should investigate the source of the performance problem before changing personnel or paperwork. Coaching, setup review, and instruction clarity often correct the issue faster than guessing.

6A subcontractor’s welders arrive for field support. Before they start work, what should the supervisor verify?

A.That each welder brought personal hand tools

B.That their qualifications and documentation meet the applicable code and project requirements

C.That they agree to use the same break schedule as the shop crew

D.That they have previous experience with the customer’s project manager

Explanation: Subcontracted personnel still need to meet the project’s qualification and documentation requirements. Convenience items like tools or scheduling do not satisfy code compliance.

7Which measure gives the best picture of crew performance in a welding department?

A.Arc time only

B.Total hours charged to the job only

C.Quality, safety, schedule adherence, and productivity together

D.How many welders ask the fewest questions

Explanation: Supervisory performance is multidimensional. A crew that works quickly but causes repairs, safety events, or schedule disruptions is not performing well overall.

8A new welding process will be introduced next month. What is the best way to prepare production personnel?

A.Wait until the first production job arrives and learn on the fly

B.Provide structured training, qualification as needed, and controlled practice before production use

C.Use the new process only on the hardest jobs first

D.Let only the fastest welders decide how the process should be used

Explanation: Process changes should be planned, trained, and qualified before the first production part is welded. Controlled preparation reduces rejects and protects schedule performance.

9A customer pressures the shop to start welding before all traveler documents are complete. What should the supervisor do?

A.Begin welding and complete the paperwork later if there is time

B.Start tack welding only so the schedule appears on track

C.Require the needed instructions and records before controlled production begins

D.Ask welders to work from memory on similar past jobs

Explanation: Supervisors are responsible for controlling work, not just accelerating it. Missing documents create traceability and compliance risk that can be more expensive than a short delay.

10What is the main purpose of an effective end-of-shift welding handoff?

A.To allow the next shift to change procedures without approval

B.To communicate status, problems, hold points, and next actions clearly

C.To transfer blame for any earlier defects

D.To reduce the need for inspection records

Explanation: A handoff keeps production controlled across shifts by transferring accurate job status and unresolved issues. It supports continuity and reduces repeated mistakes, omissions, and unsafe assumptions.

CWS Welding Study Tips from Top Performers

1Spend the most time on productivity and performance because AWS assigns that area the largest official weighting.

2Practice navigating weld symbols, notes, revision blocks, and specification references without hesitation.

3Review WPS use, preheat/interpass control, consumable handling, sequencing, and distortion prevention as a connected workflow rather than isolated facts.

4Know the supervisor's role in qualification records, inspection readiness, documentation flow, and coordination with NDE or outside parties.

5Use timed open-book drills so you build speed in standards lookup instead of assuming the book will save time automatically.

6Brush up on basic welding process theory, filler classifications, weldability, and common quality risks so you can make sound supervisory decisions.

7Study safety from a supervisor perspective: permits, ventilation, PPE, cylinder handling, confined spaces, and fire prevention responsibilities.

8Work mixed productivity problems involving deposition, operating factor, rework, fit-up, and labor utilization because Part B emphasizes economics.

Frequently Asked Questions

How many questions are on the AWS CWS exam?

AWS QC13 states that the CWS exam has two open-book written examinations: Part A has 150 multiple-choice questions on fundamentals of welding supervision, and Part B has 30 multiple-choice questions on welding practices and economics. That makes 180 questions total.

What is the passing score for CWS?

AWS QC13 requires a minimum of 70% correct answers to pass the CWS written examination(s). Because the program is governed by AWS standards, candidates should verify any current scoring or retest details in the official AWS CWS user guide before scheduling.

How much does the CWS exam cost in 2026?

AWS lists the 2026 CWS Prometric exam fee as $665 for AWS members and $756 for nonmembers on the official program price list effective January 1, 2026. Optional seminar and package pricing is higher.

What topics matter most on the CWS exam?

The largest official weighting is Productivity and Performance at 30%. Drawings and specifications, safety requirements, welding instructions, and welding practices/production controls each account for 10%, while supervision, materials, equipment, inspection, records, and standards application each account for 5%.

Is the CWS exam open book?

Yes. AWS describes the CWS written examinations as open-book exams. Candidates should still practice quick reference use because open-book welding exams are time-limited and reward efficient navigation of standards and supporting documents.

What experience is required to become a CWS?

AWS B5.9 requires a high school diploma or equivalent and at least three years of practical welding experience in fabrication, construction, or a welding-related industry. AWS also allows certain teaching experience substitutions with proper documentation, and QC13 requires proof of visual acuity as part of certification.

Are there any 2026 CWS changes I should know about?

As of March 12, 2026, AWS has published 2026 pricing effective January 1, 2026 and an online-only certification application change effective January 15, 2026 through the My AWS Portal. I did not find an official 2026 change to the underlying CWS exam weighting itself; AWS still points candidates to the CWS user guide, QC13, and B5.9 for exam structure and body of knowledge.
