Tig welding of brass

Are you interested in the technology of welding of brass alloys using the TIG method from the supplier AvecGlob? Here you will find the necessary information on this topic.

The use of tungsten non-consumable electrodes in the welding of brass

The process using such electrodes is called TIG, and it can be used to a limited extent in the manufacture of repair work with brass products. The rationale for the method lies in the fact that the installation of new brass parts is more expensive than surfacing / restoring the old ones.

Using tungsten electrodes for welding brass, the following should be considered:

In the process of welding TIG emits a lot of smoke, so an effective hood is needed, the Welder must work in a respirator, as zinc fumes are poisonous;

Welding is advisable to conduct on alternating current, using inverter welding units. The repetition rate of pulses should not exceed 30… 50 min ^-1 ;

Initially, the given amperage should be as high as possible to form a weld pool as quickly as possible. Only then a tungsten electrode is introduced into the welding zone;

It is inadmissible to overheat brass, resulting in zinc burnout;

It is advisable to use air cooling of the weld zone.

Supplier — AvekGlob Company — offers to purchase assortment of various brass alloys of domestic and foreign production. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

Features of the process

For TIG welding, predominantly direct current is used for brass. It is recommended to start welding using an increased current (like for aluminum welding), and then quickly reduce the current, to values with which a stable melt of the material in the weld pool can be maintained.

In the process of welding, a white film of zinc oxide is formed on the surface, which is obtained by oxidizing zinc released from the boiling melt. For brasses containing a high percentage of zinc, this causes porosity, so welding such brass alloys by the TIG method is not recommended. Here it is necessary to use the technology of soldering.

If the factor of the final color of the connection point is uncritical, filler is used, the melting point of which is possible further from the melting point of the welded brass.

When welding by this method of some brands of brass, intensive mixing of the metal is recommended to reduce the forces of surface tension and to reduce the percentage of oxide emission. This is especially important when filling brass materials with a decorative purpose. Stirring is performed by a tungsten electrode.
