Gas burners for brazing copper and soldering : selection of the best

Theory and Practice of the process connection of copper communications

qualitatively to dismantle the soldering connection is enough to bring it up to warm temperatures and break the pipe and coupling.Thus, using hot mounting can be created with any piping required to have functions and characteristics.

Before topic, why do you need a gas burner for brazing copper, is a set of tools to disassemble solder.

course, the main tool for the pipe connections is a soldering iron, or in other words a device for brazing, in which warming is happening and the workpiece, and solder.Next you will need to use more and auxiliary kits for joining workpieces, which consist of Flat skimmers, pipe cutter, reamer, hammer and meter.

Soldering copper using paste and flux solder

role in high-temperature soldering with fine copper wire, which is at a temperature of 600-800 ° C begins to melt and weld connection.

In turn, when the low-temperature solder wire use of tin, which burns at a lower temperature - up to 400 ° C.

If you want to apply the flux, the most liquid is applied directly on the right sleeve and the pipe in liquefied form, or as a solid welded in place soldering.

Pasta with which solder copper communications, called flux, it is represented by a thick mass, which should be applied to the product before and after docking.Flux provides absolute tightness and impede the emergence of air in the dock.You can then continue to prepare the joint assembly.

Preparation

to cook docking unit at the household piping, it is important to take advantage of special fittings required for soldering or sockets at the ends of the pipes.The implication of this - superimposition of the socket for the connecting seam.Also at this stage, the gas burner is prepared for brazing copper.

Fittings made of copper is replaced by flare connections wherever appropriate.Such cases may be possible:

Creating a thickening of the socket in the pipe takes place directly in several ways:

1. ends (the ends) Connection obvaltsovuyut Cutters and put perpendicular to the axis of the product.
2. both ends of the workpiece after the removal of facets Flat skimmers and inner and outer part of the pipe is cleaned copper brush.
3. first workpiece is conveyed in the side, and the second expanding speculum previously prepared to the necessary and possible caliber.Then flare towards internal communication, that it instead of the diameter of the first tube.The diameter of the workpiece and the degree of flaring should coincide.

When flaring the pipe and the socket end, you can proceed to the next step.

soldering pipe joint

By soldering joint should begin when the socket and the sleeve will be prepared.will sing and kind of connection type is determined in advance.

Soft welding will look like this in the photo.

there are some patterns of work:

1. details to each other to try on when collected and processed under the flared socket joint.
2. layer of flux is applied to the inner and outer side of the pipe liquid and dense composition, when all the parts are connected without wrangling.Then lay the blanks in socket assembly.
3. now need the gas burner for brazing copper, which is heated to 400 ° C and as soon as the flux begins to darken under the temperature, it is necessary to make solder.
4. The soldering zone make solder wire.Tin melts during the connection to the pipe.Then the mixture was heated by a oskolzaet flux into the seam filling the seam at this time between the pipe and socket.It is possible that a small amount of the mixture is over the seam.

Solder seals and fixes the tube.

At high temperature soldering takes place a little differently, so below we present the application of this technology in stages solder.

1. Node treated with flux paste and collected.In fact the bell placed in the clutch and they are welded blanks just two.
2. on heat-resistant surface of the assembled structure is placed, so she warmed and melted flux.
3. To the junction point of pipes and sockets introduce copper solder and connect the gas burner for brazing copper, which softens and the wire is attached to the junction and flows through the joint on the tube.
4. Then the pipe with wire solder scroll, reeling at the joint portion to weld education.

result of all actions - weld with a high level of strength and integrity.such products are best for home pipeline!
