Device and principle of operation

Gas welding is the process of joining metal components while they are exposed to a high-temperature flame, which causes welding baths to form on the surfaces of the components. Acetylene is burned using an O2 catalyst, creating a hot flare jet that ignites the flame. A torch like this is also very useful for cutting metal.

1. Gas and oxygen flow through their channels into the torch, where they mix, the resulting gas escapes through the calibrated nozzle of the acetylene torch tip.
2. The gas-fuel mixture is ignited, after that a torch is formed, the size of which is set with the help of regulating taps (valves).
3. Acetylene flame is formed of 3 parts: the core, with the highest T, the recovery and the flare. The welding process takes place in the second and third parts.
4. The open high-temperature flame protects the welding surface from contact with air oxidizer.
5. Welding begins with heating the edges of the parts, then melting and joining them together. The process requires a high gas flow rate to create a high-temperature regime.
6. Another stage is surfacing using a soft metal filler rod that saturates the weld pool at the edges.

• Propane cylinder;
• Oxygen cylinder supplying O2, which is the catalyst for the combustion process;
• hoses;
• gas burner: bronze tube, 2 regulators for each gas cylinder, calibrated nozzle for fine atomization of pressurized gas medium.

1. Possibility to regulate the distance to the welded surface and operating modes, which allows to exclude rejection in the form of burns, even in the case of joining thin metal sheets.
2. Mobility of movement and transportation on the installation and construction site.
3. Reliability and high quality of the work performed.
4. Control over the welding process.
5. Possibility of making a non-rotating weld, close to obstacles, e.g. walls, without the need to make an operating joint.
6. Creation of unbreakable metal joints with different melting point temperatures.
7. Adjusting the strength and size of the welding flame.
8. Improving weld quality with the use of alloying steel wire.
9. Elimination of deformation shifts of the structure and joint by adjusting the heating temperature, thereby achieving the design mode of welding metals.
10. Low cost of equipment and consumables for the device.

Cons of utilizing a tiny acetylene torch:

1. Work may only be carried out by trained and certified workers.
2. Low welding productivity.
3. Change of chemical and structural properties of the material over a large heating area.
4. The use of acetylene creates a high fire hazard in the environment;

7. Impossibility of overlap welding.

Selection criteria

Welding acetylene requires inexpensive, widely available equipment. Gas was formerly obtained through gas generators, but cylinder acetylene is now utilized more frequently. It has white paint on its cylinder. Cylinder oxygen is used, and it is transported on specially made carts, to carry out the oxidation process.

Several torch sizes exist, identified by the welded metal’s thickness. Zero is the lowest number and seven is the highest. For acetylene gas flame treatment, only acetylene torches are utilized. The primary factor influencing their decision is the technical aspects of the work: the welded products’ thickness, the material’s chemical makeup, and the tip diameters. These factors will determine the connecting seam’s size and the operation’s overall performance quality. In this sense, the requirements for the processed parts are taken into consideration when choosing an acetylene torch.

The most popular torches in use today are:

1. G2 to carry out welding with various tips, from 0 to 4 size inclusive, with a thickness of parts from 0.2 to 7.0 mm and a maximum welding speed of up to 200 mm/min.
2. G3, Donmet-251 for welding of metal up to 30 mm thick.0 mm, with tips from 2 to 7 sizes and maintenance of the oxygen and acetylene pressures. For example, for welding of elements with thickness from 7.0 to 11.0 mm use No 5 tip, with oxygen pressure from 2 to 3 kgf/cm2, and acetylene pressure from 0.4 to 1.0 kgf/cm2. Welding speeds of up to 45 mm/min can be achieved.
3. Torch R2A-02M "Svarog", is designed for cutting sheet of ferrous metals.
