1. 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 is the Specification for Brazing Procedure and
Performance Qualification, establishing the requirements for qualifying
brazing procedures, brazers, and brazing operators.
2. What is the primary purpose of brazing?
a) To fuse base metals together by melting them
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 that has a lower
melting point than the base metals, leaving the base metals solid.
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), whereas soldering occurs below that
threshold.
4. Which of the following is a common brazing filler metal?
a) E7018
b) ER70S-6
c) BAg-1
d) ER308L
Rationale: The BAg series (silver-based alloys) are standard brazing filler
metals; E7018 and ER70S-6 are welding electrodes/rods.
5. 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 “B” stands for braze and “Ag” is the chemical symbol for silver,
designating a silver-based brazing filler metal.
6. 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 dissolves and removes oxides from the joint surfaces and
promotes wetting so the filler metal can flow evenly.
7. 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
Rationale: A brazing procedure qualification test verifies joint performance
under prescribed conditions as required by AWS B2.2.
, 8. 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 such as base metal, filler
metal, flux, heating method, and joint details to be documented.
9. What type of joint clearance is ideal for brazing?
a) 0.5–1.0 mm
b) 2–3 mm
c) 0.03–0.13 mm (0.001–0.005 in.)
d) 1–2 mm
Rationale: Brazing requires a narrow gap (typically 0.001–0.005 in.) to allow
capillary action to draw the filler metal into the joint.
10. Capillary action in brazing refers to:
a) Pressure welding
b) The drawing of molten filler metal into the joint clearance by surface
tension
c) The melting of the base metal
d) The oxidation of the filler metal
Rationale: Capillary action is the mechanism by which molten filler metal is
pulled into a closely fitted joint by surface tension forces.
11. Which of the following is the primary difference between brazing and
welding?
a) Brazing melts the base metal while welding does not
b) Brazing uses a filler metal with a melting point above 450 °C
c) Brazing does not melt the base metal
d) Brazing always requires an electric arc
Rationale: Brazing joins metals by melting a filler metal that has a lower
melting point than the base metals; welding melts the base metals
themselves.
