Brazing Copper Pipe With Oxy Acetylene

It is the gas that used to power miner s headlamps.

Brazing copper pipe with oxy acetylene. This torch can be used for welding most medals including steel. Jeff shows how to braze using an oxygen and acetylene how to set your gas mixture and the correct way to light your torch. Acetylene is a gas that made by adding water to carbide rocks. The oxy acetylene torch has the highest temperature flame that is normally used in brazing.

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. The neutral flame has a well defined inner cone see diagram. For most brazing jobs using oxygen acetylene gases a carburizing or neutral flame should be used. Excess acetylene removes surface oxides from the copper.

At the end of the. Also they must continuously move the torch around the diameter of the pipe to evenly distribute the heat. 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.
