For most brazing jobs using oxygen acetylene gases a carburizing or neutral flame should be used.
Brazing copper pipe with oxy acetylene.
The neutral flame has a well defined inner cone see diagram.
Jeff shows how to braze using an oxygen and acetylene how to set your gas mixture and the correct way to light your torch.
Also they must continuously move the torch around the diameter of the pipe to evenly distribute the heat.
Avoid an oxidizing flame.
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.
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.
Excess acetylene removes surface oxides from the copper.
In addition to the purposes of welding connecting gas welding can also be used as preheating brazing cutting and hard facing.
It is the gas that used to power miner s headlamps.
The oxy acetylene torch has the highest temperature flame that is normally used in brazing.
