Definitions
A material having metallic characteristics and made up of two or more elements, at least one of which is a metal.
What is an alloy?
This brazing filler metals can be used to join most ferrous and non-ferrous metalsexcept aluminum and magnesium.
Silver Filler Metals (BAg)
This alloy is made up of 66% Cu and 34% Zn
Yellow Brass
One of the most common Fluxes (milk wont help)
Zinc Chloride
A welding process using a filler metal that is liquid above 425ºC(800ºF) and is not distributed by capillary action.
Braze Welding
These filler metals should not be used on ferrous or nickel alloys, or copper-nickel alloys with a nickel content exceeding 10%.
Copper-Phosphorus Filler Metals (BCuP)
This alloy is made up of 90% Cu and 10% Sn
Bronze
_______ are deoxidation agents (also known as cleansing agents) used in welding, braze welding, brazing, and soldering.
Fluxes
A joining process using filler metals that are liquid above 450°C closely fitted surfaces by capillary action. This does not involve melting of the base metal. Also known as low temperature ______ and silver soldering
Brazing
A flux is recommended with one exception. When brazing clean copper to copper, no flux is required, as the filler metals have self-fluxing properties due to the phosphorus content.
Copper-Phosphorus Filler Metals (BCuP)
The only process acceptable for joining malleable cast iron.
Braze Welding
this additive is an acid added to flux that can cause corrosion and in extreme cases perforation of the tube and/or fittings.
Zinc Chloride
The specific alloy compositions that melt at one temperature and not over a range. In this respect, These alloys behave like pure metals
Eutectic Composition
The primary purpose of ______ is to keep the surface of the metal free of oxides during the heating and filling process.
Fluxes
The 3 factors of deciding which type of solder to use for a job
Max Temp
Max Pressure
Tube Size
If the tolerance is incorrect, there will be insufficient penetration of the solder which can result in the ultimate failing strength of the joint being reduced by as much as _____%.
80%
A form of surface tension between the molecules of a liquid and those of a solid
Capillary Action
This organization developed specifications and classifications for oxyfuel brazing and braze welding filler metals
Solder containing ___% tin is available for radio and electronic work where a harder alloy with good conductivity is desired.
60%
When preparing to solder a joint, this is done after cutting the copper tube to length?
Ream the tube
