L2Q5 Study Soldering and Brazing
Alloy: - Answer-Any substance made up of two or more metals.
Brazing: - Answer-A method of joining metals with a non- ferrous filler metal using heat above 800°F but
below the melting point of the base metals being joined. Also known as hard soldering.
Capillary action: - Answer-
Capillary action: - Answer-The movement of a liquid along the surface of a solid in a kind of spreading
action.
Flashback arrestor: - Answer-A valve that prevents the flame from traveling back from the tip and into
the hoses.
Flux: - Answer-A chemical substance that prevents oxides from forming on the surface of metals as they
are heated for soldering, brazing, or welding.
Nonferrous: - Answer-A group of metals and metal alloys that contain no iron.
increasing the amount of air - Answer-If there are indications that incomplete combustion is occurring,
the problem is solved by
350°F to 600°F - Answer-The temperature range of the flue gases in an induced-draft furnace is
