Cutting of brass

Cutting brass perform by way of plastic deformation and mechanical means. The first group consists of technologies cutting brass rolling scissors. Assorted metal cut shears, sheet — crank shears with inclined blade. the methods of cutting by shear can be attributed to the high-speed pulsed cutting with the use of wedge-shaped knives.

Core technologies mechanical cutting of brass are cutting on friction saws, mechanical hacksaw toothed saws. Much less common anode-mechanical cutting. Cutting electrical discharge machines using non-profiled electrode for brass is not used, owing to the wear of the wire electrodes.

Welding brass

Welding of brass by conventional methods is impossible, because elevated temperatures lead to the formation of surface products intensive oxide film, preventing welding. In addition, when heating the brass to the melting points begin to form volatile gaseous compounds of zinc, which are hazardous to human health. Another technological difficulty lies in the fact that the rapid heating of the brass in the range of 300…450°C leads to the formation of cracks.

Optimization of welding

For high-quality welding requires the use of special welding fluxes, which prevent the access of oxygen to the zone of formation of the weld. The filler material is more commonly used brass alloy wire, which contain a higher percentage of silicon. As a result, not only increase the strength characteristics, but also eliminates the burning of zinc. With the same purpose in welding using «short arc», with a length of not more than 15 mm, and a voltage not exceeding 25 V.

Argon welding

Argon welding occurs in the following sequence:

• Carefully prepared edges of connected products. Kind of cutting is determined by the thickness of parts: if it does not exceed 1…1,5 mm, that performs flanging of the edges, with thickness up to 5 mm — sided cutting, for thicker workpieces it is necessary to make an X-shaped preparation of edges;
• Edges, in addition to Stripping is subjected to the processing in concentrated sulfuric acid, which most efficiently removes all contaminations;
• Welding should only be exposed to well dried billet;
• Argon flow in the zone of formation of a weld with a flow rate not below 100…110 DM³/h per 1 mm of the weld, with the formation of the weld it is desirable to perform a burner nozzle which is located perpendicular to the welded surfaces.
