Oxy acetylene welding oxy acetylene welding and sheet metal.
Brazing sheet metal oxy acetylene.
While alternate fuel gases are available most contractors still use acetylene.
When brazing and soldering most hvacr technicians routinely use manual torches as their heat source.
In addition to the purposes of welding connecting gas welding can also be used as preheating brazing cutting and hard facing.
Oxy acetylene gas welding brazing and braze welding these are older methods of joining thin metal sections that still have some application in today s world of mostly electric welding.
With the acetylene valve on the torch slightly open adjust the regulator pressure to the correct reading then close the torch valve.
Jeff shows how to braze using an oxygen and acetylene how to set your gas mixture and the correct way to light your torch.
This is one of the widely adopted.
Repeat the same procedure for the oxygen.
Read our general safety precautions before starting your project.
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.
After brazing use a wire brush to clean the brazed surface to remove any oxidation or residue.
For large areas heat portions of the joint to temperature and then move to the next adjacent area.
Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s.
Apply the brazing rod to the joint while continuing to heat the metal surfaces.
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.
For brazing there are generally two equipment options to choose from.
Start by open the valve on top of the oxygen cylinder all the way and the valve on top of the acetylene cylinder 1 turns.
In most cases they will prove inferior in one or more of several ways to electric welding approaches.
Heat the joint where the two pieces of metal will meet until the joint glows.
