Oxy-Acetylene Welding Oxy-Acetylene (OA) welding is one of the many types of welding supported by the PRL. It is extremely versatile, and with enough skill and practice you can use this type of welding for virtually any metal. In fact, the oxy-acetylene flame burns at 6000 °F, and is the only gas flame that is hot enough to melt all commercial ...
Thus oxy-acetylene welding enables accurate control of both the size and type of flame which is very important for joining non-ferrous materials and metals of small section. Correct flame adjustment is essential for the production of sound welded joints by the oxy-acetylene process. The two important considerations are:
Oxy-Acetylene Welding is the welding process of heating two pieces of metal to melting point, bringing the parts together and while still in a molten stage hammered together to form a joint. Learning how to weld using this process will give a complete overview of welding. The Oxy-Acetylene Welding process requires the use of a …
The oxy-acetylene (and other oxy-fuel gas mixtures) welding torch remains a mainstay heat source for manual brazing and braze welding, as well as metal forming, preparation, and localized heat treating. In addition, oxy-fuel cutting is still widely used, both in heavy industry and light industrial and repair operations.
The pressures needed to braze with different metals differ, but the ratio of oxygen to acetylene should always be 2 to 1. To use bronze, a common brazing material, the acetylene regulator should be set for 5 psi and the oxygen for 10 psi.

ADVERTISEMENTS: Subject-Matter of Oxy-Acetylene Cutting Process: In modern steel-age the steel-makers cut Iron and Steel by oxy-acetylene, oxy-hydrogen, oxy- propane, oxy-natural gas cutting blowpipes easily, speedily, and cleanly. Cutting of metals by means of flame has many advantages over other methods, specially when the metal is of irregular shape. When using oxy-acetylene a special torch
Acetylene is used as fuel for oxy-cutting and oxy-welding . When mixed with oxygen, it's the most effective gas to form a flame hot enough to cut and weld most metals with ease. It's more expensive than some other fuel types, but it's the best type of fuel to use.
The welding can be done by either fore hand or back hand position. The weld is usually reinforced 1/16”above the pipe wall upto a thickness of 3/8” and 1/8” for 3/8” an above. The width of the bead should be approximately 1 ½ to 2 times the wall thickness. Fig 6 Rolling Method of Welding Pipe. Fixed position welding.
Aug 02, 2018 · 2. OXY-ACETYLENE WELDING It is the common method of gas welding. The oxy-acetylene welding process combines oxygen and acetylene gas to provide a high temperature flame for welding. This temperature provides enough heat to melt most metal. The chemical reaction between acetylene and oxygen is exothermic in nature. Oxy-acetylene flame may also ...
Oxy-fuel welding is a process that uses heat created by a gas flame to melt the base material. The gas flame created by combustion of oxygen and acetylene produces temperatures of 5600 to 6000 degrees, which is the hottest of any gas flame and is capable of melting almost any metal.
Oxy-acetylene welding torch Oxygen and the fuel gas having been reduced in pressure by the gas regulators are fed through suitable hoses to a welding torch which mixes and controls the flow of gases to the welding nozzle or tip where the gas mixture is burnt to produce a flame for carrying out gas welding operation.
Guidelines are given on the principal health and safety considerations for oxyacetylene welding to ensure safe welding practices. The oxyacetylene process The oxyacetylene process produces a high temperature flame, over 3000 degrees C, by the comb...
Oxy acetylene welding can be used if quickly joining metals together is your only concern because the weld seam formed is not as neat as the ones created by other welding methods. A neutral flame is also used for welding using a cutting torch, but you need to move your torch in a circular manner so that the metals will melt and pool towards the small gap present between them.
_Welding._--Oxy-acetylene welding is an autogenous welding process, in which two parts of the same or different metals are joined by causing the edges to melt and unite while molten without the aid of hammering or compression. When cool, the parts form one piece of metal. The oxy-acetylene flame is made by mixing oxygen and acetylene gases in a
How Does Torch (Oxy-acetylene) Welding Work? The oxy-fuel welding method combines oxygen and a gas (typically acetylene) to create a very hot flame that can cut through metal. The oxygen and acetylene levels can be adjusted on the torch to create the ideal flame for cutting metal or fusing metals together. In the context of comparing torches to ...

Introduction to Oxy-Acetylene Welding Revision 2.0 September 2014 2.0 Identifying Oxy-Acetylene Welding Equipment 2.1 Gas Cylinders Leakage around the spindle of the cylinder valve will be revealed by hissing and in the case of fuel gases, by a smell. Tighten the gland nut on the cylinder valve
Apr 16, 2017 · Gas welding is a type of liquid state welding process in which fuel gases burns to generate heat. This heat is further used to melt interface surfaces of welding plates which are held together to form a joint. In this process, mostly oxy-acetylene gas is used as fuel gas. This process can be done with or without help of filler material.
Process features. Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg.C.
For economy and safety reasons, other gases, such as natural gas, propane, hydrogen and proprietary gases based on mixtures of these, are frequently used for non-welding processes. Table 8-1 shows the maximum temperature achievable with these alternative fuel gases as compared with the temperature of acetylene.
Mar 11, 2019 · 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. In addition to the purposes of welding (connecting), gas welding can also be used as preheating, brazing, cutting, and hard facing.
