BRAZING/SOLDERING VOCABULARY 1 Flashcards
BRAZING
-Common term for a metal joining process by which copper pipe/tubing is connected with a high-temp filler metal (melted at around 1200 degrees), and is commonly used in refrigeration lines
SOLDERING
-Common term for a similar process to brazing, but done at a lower temp (around 600 degrees), and is used for low-pressure water lines, uses flux
ACR COPPER
pipe and tubing,
which is sized directly by its outside diameter (OD) and a typed letter indicating wall thickness.
TYPE K COPPER
is the thickest type of copper pipe, is used for water and oil transportation, fire protection, and HVAC applications. Its primary use is for main water lines and underground lines due to its durability to withstand intense pressure.
TYPE L COPPER
is medium weight copper, is used for indoor plumbing, fire safety, and HVAC purposes. Technicians use it primarily to repair and replace old interior branch water lines, but it’s also effective for outdoor applications.
TYPE M COPPER
MUCH THINNER COPPER TYPE, is used for household water distribution and vacuum systems. It’s ideal for repairing, extending, and replacing interior branch water lines. DOES NOT MEET ALL CODES, SO IT MUST BE CHECKED BASED ON THE APPLICATION.
BRAZING ROD
are pieces of metal that melt during the welding process and attach to the separate pieces of metal to join them together once cooled.
PLUMBING SOLDER -
Solder is a filler metal that goes into the joint between two pieces of pipe. It’s a metal alloy, or mix of metals. Soldering used to be done with lead alloys.
PLUMBING FLUX -
Flux is a chemical compound that helps prepare the metal surfaces for soldering by removing oxides, promoting wetting, and enhancing the flow of solder
SILVER SOLDER
usually refers to a stronger solder used for mechanical joins However, it has a higher melting temperature (ARQUND 1000 DEGREES), which means the parts have to be heated to a higher temperature to make it work MaNly useD for Disilar metals
