How to make a gas burner for welding metal with your own hands: device, principle of operation, production

April 30, 2020

Gas soldering torch is known to many home builders, which often deal with piping systems. The main purpose of this tool is to establish a mixture of oxygen and fuel gas. Thanks to this device, you can provide a stable flame of the required power. Gas burners can be special purpose and universal.

To perform surfacing operations, welding and other types of processing of metal products using the gas-flame connection method, use appropriate units. The gas burner has many positive qualities, among which it is necessary to mention the resistance of the flame, which persists even in strong winds. This creates comfortable working conditions, held outdoors.

Fundamental device

Certain elements can be distinguished in the design of a gas burner for soldering copper pipes:

  • node, which is the location of gas cylinders;
  • nozzle;
  • device head;
  • gas supply regulator;
  • reducer.

There are some models of burners for soldering copper pipes, in the equipment of which special additional elements can be provided. Let's say, such devices may be equipped with automatic piezo ignition, adapters, designed for propane cylinders of various shapes, wind protection, conveying cover, etc. Due to this configuration greatly simplifies the process of soldering copper pipes.

Gas burners for soldering copper pipes may differ from each other on the following grounds, as the thickness and shape of the metal, used to work with such a device. There are also special gas burners for soldering copper pipes, designed for a specific type of gas.

The procedure for working with a gas burner for soldering

Even before you start using these devices for soldering copper pipes, you should make sure, that the tool is in working order. Preparatory activities are limited to the inspection of detachable joints, soldered and sleeve joints to detect leaks.

Once you can make sure there are no problem areas, you can choose the working pressure of the gas, based on the task. Then you need to open the valve half a turn, then the hot mixture is ignited, and, using a valve or reducer gas mini-burner, begin to adjust the intensity of the flame. After performing the above operations, the main tool for welding pipes made of copper or other metal products will be ready for use.

Homemade vodka for soldering copper pipes

It is time to get acquainted in more detail with the device of the gas device for soldering of ejection type, designed to work with metals in high temperatures. The source of the manual gas burner is a cylinder, containing liquefied gas. Such a device is highly economical, as it is possible to adjust the intensity of the gas supply.

How a torch for soldering copper pipes works

Manual type gas burner has a fairly simple design, which fully applies to the principle of its operation. The gas supply is provided by the ventilated crane, located on the cylinder or hose of the gearbox. As it moves, it enters the supply tube, located at the base of the burner. Once there, the gas goes into the vertical channel of the rack, from where it enters the central hole of the nozzle.

Then the gas begins to enter the jet in accelerated mode, and, without losing pace, comes out of the hole. After that, it is sent through the radiator duct to the diffuser. This process is accompanied by support from the air spool, without which it is impossible to ensure the combustion process. Once in the diffuser, the mixture begins to split into two streams: auxiliary and main.

The ejector is equipped with a rotating spool sleeve, which provides radial holes, due to which it is possible to adjust the amount of air, incoming.

What is homemade vodka for soldering

The following main components can be distinguished in the device of the gas unit for soldering:

  • special needle to change the intensity of gas supply;
  • slice, providing access to the nozzle;
  • needle handle;
  • jet body;
  • burner base;
  • stuffing box;
  • fastening nut;
  • ejector;
  • spool sleeve;
  • cracks;
  • spool holder;
  • divider;
  • radiator;
  • pen, which provides convenience of work;
  • gas supply tube.

How to make a burner with your own hands?

Except for the handle, the process of making the elements of the burner, intended for tinning, is carried out on a lathe. And it is best to create elements based on brass or bronze. Copper will be an unsuitable option. The choice in favor of these metals is due to the fact, that they have high thermal conductivity characteristics, as well as resistance to corrosion and high strength.

In the manufacture of the nozzle body, directly to the nozzle and cover it is desirable to use steel. It is recommended to use a steel knitting needle to create an adjusting needle. For oil seal, used for thread sealing, it is recommended to take fluoroplastic. So, in the presence of the specified materials it is quite real to make a self-made torch for soldering of products, including pipes, with their own hands.

It should be noted, that in the presence of the drawing to create a gas burner is not so difficult. But this work takes a lot of time, this primarily applies to the nozzle. Create an outlet the size of 0,1 mm is possible, drilling a through hole, whose diameter must be equal to 0,4 mm. Next you need to take a small ball, and with its help, doing everything extremely carefully, wait for the hole created, bringing it to the required size.

Burner assembly

The assembly procedure itself involves such stages:

  1. You need to take the nozzle and wrap it in the case, before performing this operation, a layer of epoxy resin should be applied to the joints.
  2. On the reverse side of the housing it is necessary to create a seal based on fluoroplastic, and then tighten it with a threaded cover with an adjusting needle.
  3. To install the nozzle housing is given space in the base of the gas device, and then it is fixed with a clamping nut.
  4. The ejector is installed on the body by screwing it, after that the spool part fastens, including radiator and dividers.

So, should come out a reliable portable burner, with which you can weld metal products, including pipes, of different metals.

Conclusion

The wide choice of various devices for soldering of metals and preparations from it allows to pick up the most suitable option. Gas burner is able to effectively cope with this task. And you don't have to follow her to the store. If you prepare all the necessary materials and tools and thoroughly study the manufacturing technology, then such devices can be assembled with your own hands, thus saving on assembly.

Before you start creating a gas burner, it will be useful to get acquainted with its principle of operation and device. Such knowledge will be useful for that reason, that it will help simplify the procedure of its manufacture, considering, that the master will have an idea of, what elements make up the burner and what role each of them plays in the work.
