BRAZING ACTUAL TEST FULL QUESTIONS
AND CORRECT ANSWERS EXAMPREP
STUDY SHEET
●● 4 S'
Answer: Sparking, spitting, spattering or sputtering of the filler alloy is
prevalent whe using oxy-acetylene torch, the torch tip is too small or you
are using an oxidizing flame
●● When rebrazing or brazing a horizontal joint
Answer: it's good practice to feed the alloy into the joint at the 9 o'clock
position, not the 6 or 12 o'clock
●● Improper Heating of joint
Answer: overheating one member of the joint and underheating the other
will cause the ally to flow over the outside rather than entering the joint.
Improper heating and cleaning techniques can result in Capping the joint
or a joint with numerous voids
●● Applying Heat
Answer: Use proper tip size. Use a smaller flame for better control.
, ●● A carburizing flame coming from an oxyacetylene torch has 3 parts.
What are they?
Answer: A gas flame in which there is excess fuel gas, resulting in a
carbon rich(reducing) zone extending around and beyond the cone too
much fuel gas, has a slightly green feather on the outer cone, torch runs
quieter than nuetral flame.
●● oxidizing flame
Answer: A gasflame in which there is excess oxygen. Produces a porous
joint with very little alloy penetration
●● A neutral flame
Answer: A gas flame in which is neither oxidizing nor reducing zone, the
zone, cone, and mantel.
●● Misalignment
Answer: can produce voids in the joint, a potential for leaks
●● Improper Cleaning
Answer: will cause the alloy to ball up and adhere to itself
●● A clean surface
Answer: will cause the alloy to lay out smoothly throught the joint
