Brazing sheet metal oxy acetylene.

If there is too much acetylene flame breaks away from the tip. Safety equipment plus procedures for safe operation. Slowly add oxygen flame will sharpen and elongate. The most popular is still the oxy acetylene mixture.

But there are times when you may find uses for torch welding and brazing techniques. Oxy acetylene welding oxy acetylene welding and sheet metal. Oxidizing excess oxygen to acetylene burning ration with on acetylene feather and makes a harsh hissing sound least used because it oxidizes metal but is used for braze welding with a bronze rod neutral x burns equal amounts of oxygen and acetylene and has a clean clean edged inner cone the most used flame for oxyacetylene applications. Brazing is a form of non fusion welding.

The oxy acetylene flame generated by mixing oxygen and acetylene gases to fuel a torch is infernally hot about 6 300 degrees f at the cone tip of a neutral flame. After brazing use a wire brush to clean the brazed surface to remove any oxidation or residue. At the end of the. Oxy acetylene gas welding rods the oxy fuel process is considered old school.

And this welding process is still very popular today mainly because it does not require much equipment and does not require power. If the pressures are adjusted correctly for the size of the torch opening there should be little to no hissing noise coming from the torch. Once the torch flame is adjusted correctly you are ready to braze. Apply the brazing rod to the joint while continuing to heat the metal surfaces.

In torch brazing a variety of fuels are available natural gas acetylene propane propylene etc combusted with either oxygen or air. Adjust acetylene to form feather shaped flame. Heat the joint where the two pieces of metal will meet until the joint glows. Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s.

For large areas heat portions of the joint to temperature and then move to the next adjacent area. Continue to add oxygen until neutral flame is established. Continue opening the oxygen until the acetylene cone disappears into the white inner cone. In addition to the purposes of welding connecting gas welding can also be used as preheating brazing cutting and hard facing.

It s popular with metal artists and also used for soldering and brazing dissimilar or non ferrous metals. In most shops acetylene gasis combined with oxygen to produce the torch flame.
