AWS AWS Certification & Qualification 5 — Questions and Answers
Question 1: A Senior Certified Welding Inspector (SCWI) differs from a CWI primarily in that the SCWI:
- Can perform destructive testing without laboratory support
- Has demonstrated advanced knowledge and a minimum of 6 years of welding inspection experience (Correct answer)
- Is certified by ASNT rather than AWS
- Must hold a professional engineering license
Correct answer: Has demonstrated advanced knowledge and a minimum of 6 years of welding inspection experience
The SCWI designation requires a minimum of 6 years of welding inspection experience along with passing a more advanced examination demonstrating higher-level knowledge.
Question 2: Under AWS QC1, if a CWI's certification lapses by more than 1 year, what is typically required for reinstatement?
- Submission of a new vision statement only
- Payment of a reinstatement fee with no additional testing
- Retaking and passing all portions of the CWI examination (Correct answer)
- Completing 40 hours of continuing education
Correct answer: Retaking and passing all portions of the CWI examination
A CWI whose certification has lapsed for more than one year must retake and pass all three parts of the CWI examination to be reinstated.
Question 3: Which essential variable change in a WPS for GMAW would require requalification according to AWS D1.1?
- Changing the wire feed speed by 5%
- Changing the shielding gas composition (Correct answer)
- Changing the welding gun angle by 2 degrees
- Changing the travel speed by 3 inches per minute
Correct answer: Changing the shielding gas composition
Shielding gas composition is an essential variable for GMAW under AWS D1.1; changing it requires a new procedure qualification.
Question 4: The AWS Certified Robotic Arc Welding (CRAW) credential is targeted at personnel who:
- Program and operate robotic welding systems (Correct answer)
- Inspect robotic weld cells for OSHA compliance
- Design robotic welding fixtures and tooling
- Sell robotic welding equipment to manufacturers
Correct answer: Program and operate robotic welding systems
The CRAW certification validates the skills of personnel who set up, program, teach, and operate robotic arc welding systems in manufacturing environments.
Question 5: When performing a bend test for welder qualification per AWS D1.1, which result would cause the specimen to FAIL?
- Minor surface roughness along the convex face
- An open discontinuity exceeding 1/8 inch (3 mm) measured in any direction (Correct answer)
- Slight discoloration at the weld toes after bending
- Root penetration visible on the convex surface of a face bend
Correct answer: An open discontinuity exceeding 1/8 inch (3 mm) measured in any direction
AWS D1.1 specifies that a bend test specimen fails if any open discontinuity exceeds 1/8 inch (3 mm) in any direction on the convex surface after bending.
Question 6: Which of the following best describes a 'prequalified WPS' under AWS D1.1?
- A WPS that has been tested and approved by an independent laboratory
- A WPS that conforms to all prequalified joint, material, and process requirements so no PQR is needed (Correct answer)
- A WPS approved by AWS headquarters for unlimited use across all projects
- A WPS based solely on the welder's previous qualification records
Correct answer: A WPS that conforms to all prequalified joint, material, and process requirements so no PQR is needed
A prequalified WPS meets all the specific requirements of AWS D1.1 for joints, materials, and processes, exempting it from the requirement to be supported by a PQR.
Question 7: AWS QC1 requires the CWI examination to consist of how many parts?
- Two parts: fundamentals and code
- Three parts: fundamentals, practice, and code book (Correct answer)
- One comprehensive exam covering all topics
- Four parts: vision, fundamentals, practical, and interview
Correct answer: Three parts: fundamentals, practice, and code book
The CWI exam is divided into three parts: Part A (Fundamentals), Part B (Practical), and Part C (Code Book), all of which must be passed to earn certification.
