ORACCA - BRAZING CERTIFICATION 2025/2026 EXAM
QUESTIONS AND REVISED ANSWERS GRADED A+
Base Material
The material that is cut and welded, brazed or soldered
Braze
The demonstration that a brazed joint or a soldered joint made by a specific
procedure can meet prescribed standards
Quench
Accelerated cooling, frequently in liquid oil or water
Porosity
Cavity type discontinuities formed by gas entrapment during solidification
Brazing
A metal joining operation where the base metal is not melted during the bonding
operation, capillary action draws the filler alloy into the joint and the brazing alloy
is a non-ferrous metal of a composition other than that of the metals being joined
Soldering
A group of processes producing coalescence of materials by heating them to
temperatures below 800 degrees F in the presence of filler meta
A weld produced by heating an assembly to the brazing temperature using a filler
metal
Liquidus
The lowest temperature at which a metal or alloy is completely liquid
Brazed joints classifications
Class A joints are those subjected to high or cyclical stresses and the failure of which
could result in risk to persons or property, as well as significant operational failure.
Class B joints are those which have a cumulative void of 25% or less in the filler
alloy and the failure of which could result in risk to persons or property, as well as
significant operational failure
