Brazing Copper Pipe With Oxy Acetylene

With the temperature of an oxy acetylene flame more than 3000 o f degrees hotter than the 1100 to 1500 o f required for brazing technicians need to hold the torch farther away so as not to melt the base material copper melts at 1981 o f.

Brazing copper pipe with oxy acetylene.

The neutral flame has a well defined inner cone see diagram. Oxy acetylene welding is a welding process manually in which the surfaces to be joined which is warming to melt by a gas flame oxyacetylene with or without filler metal where the connection process without emphasis. Acetylene is a gas that made by adding water to carbide rocks. This torch can be used for welding most medals including steel.

Brazing smaller pipes is possible with a small propane torch but larger pipes such as 1 and up require more heat therefore it s recommended to use an oxy acetylene system with an appropriate torch seeing silver solder melts at a higher temperature than normal solder. Avoid an oxidizing flame. For most brazing jobs using oxygen acetylene gases a carburizing or neutral flame should be used. Also they must continuously move the torch around the diameter of the pipe to evenly distribute the heat.

In addition to the purposes of welding connecting gas welding can also be used as preheating brazing cutting and hard facing. Excess acetylene removes surface oxides from the copper. It is the gas that used to power miner s headlamps.
