BRAZING COMPREHENSIVE TEST SCRIPT
2026 FULL QUESTIONS AND CORRECT
ANSWERS GRADED A+
●● Filler metal that is melted.
Answer: The liquid is the
●● The base metal or materials that are not melted.
Answer: The solid is the
●● Metallurgical bond.
Answer: the special type of atomic bonding holding metal atoms
together. This happens with the base metal and filler because no alloying
or melting of the base metal occurs.
●● Brazing.
Answer: Occurs at temps above 840F. The parts being joined must be
fitted so that the joint spacing is very small (.025-.002in).
●● Capillary action.
Answer: the combined force of attraction among water molecules and
with the molecules of surrounding materials
, ●● Braze welding.
Answer: Differs from straight brazing in that capillary action is not
required to distribute the filler metal. Here the molten filler is simply
deposited by gravity.
●● Soldering.
Answer: Takes place at temps below 840F. A process in which the
workpiece and solder are heated to soldering temp to form a joint.
●● What is the only difference between brazing and soldering?.
Answer: The temp at which they take place.
●● Tensile strength.
Answer: A joints ability to withstand being pulled apart.
●● How much stronger is a brazed joint than the filler metal and joint
alone?.
Answer: 4 to 5 times stronger.
●● As the joint spacing decreases?.
Answer: The surface tension increases the tensile strength of the joint.
●● Shear strength.
