Brazing Certification Performance Qualification (AWS B2.2) Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- Which AWS document governs the qualification of brazing procedures
and brazers?
a) AWS D1.1
b) AWS B2.2
c) AWS A5.8
d) AWS C3.2
Rationale: AWS B2.2 specifically establishes qualification requirements for
brazing procedures, brazers, and operators.
- What is the primary purpose of brazing?
a) To fuse base metals together by melting them 1 / 4
b) To use adhesives for bonding
c) To join metals using a filler metal without melting the base metals
d) To weld using high current
Rationale: Brazing joins metals by melting a filler metal with a lower
melting point than the base metals.
3. The temperature range that distinguishes brazing from soldering is:
a) Below 400°C
b) Above 700°C
c) Above 450°C (840°F)
d) Between 100–200°C
Rationale: Brazing is defined by using a filler metal with a melting
temperature above 450°C (840°F).
- Which of the following is a common brazing filler metal?
a) E7018
b) ER70S-6
c) BAg-1
d) ER308L
Rationale: BAg series (silver-based) alloys are standard brazing filler
metals.

- What does the prefix “BAg” indicate in AWS filler metal classification?
a) Brass alloy
b) Aluminum bronze
c) Silver-based brazing alloy
d) Gold-based alloy
Rationale: The “BAg” designation indicates a silver-based brazing filler
metal.
- What is the main function of flux in brazing?
a) To cool the metal
b) To add strength to the joint
c) To remove oxides and promote wetting of the filler metal
d) To prevent base metal melting
Rationale: Flux cleans oxides and helps filler metal flow evenly over the
joint surfaces.
- What process can be used to qualify a brazing procedure under AWS
B2.2?
a) Fillet weld test
b) Macroetch examination
c) Brazing procedure qualification test
d) Radiographic test only 3 / 4
Rationale: A brazing procedure qualification test verifies joint performance
under prescribed conditions.
- Which of the following parameters must be recorded during brazing
qualification?
a) Color of the filler metal
b) Power source brand
c) Base metal, filler metal, flux type, heating method, and joint design
d) Operator’s weight
Rationale: AWS B2.2 requires essential variables like base metal, filler
metal, and joint details to be documented.
- What type of joint clearance is ideal for brazing?
- 0.5–1.0 mm
- 2–3 mm
- 0.03–0.13 mm (0.001–0.005 in.)
- 1–2 mm
Rationale: Brazing requires a narrow gap to allow capillary action for filler
metal flow.
10. Capillary action in brazing refers to:
a) Pressure welding
