Brazing Copper Pipe With Oxy Acetylene

Brazing copper pipe with oxy acetylene.

Also they must continuously move the torch around the diameter of the pipe to evenly distribute the heat. Excess acetylene removes surface oxides from the copper. For most brazing jobs using oxygen acetylene gases a carburizing or neutral flame should be used. In addition to the purposes of welding connecting gas welding can also be used as preheating brazing cutting and hard facing.

Acetylene is a gas that made by adding water to carbide rocks. This torch can be used for welding most medals including steel. Avoid an oxidizing flame. 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.

Jeff shows how to braze using an oxygen and acetylene how to set your gas mixture and the correct way to light your torch. 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.
