Brass welding problems

Welding connections of brass parts by conventional methods is impossible, because at high temperature a dense oxide film forms on the surface of the products, preventing welding. Moreover, heating brass parts to the melting temperature leads to intensive burning out of zinc with the formation of volatile gaseous compounds that are hazardous to human health. Another technological difficulty is that rapid heating of brass to 300...450°С leads to cracking.

Preliminary welding operations

High-quality welding results are possible if the following steps are carried out sequentially:

• Carefully prepare the edges of the items to be joined. The type of cutting is determined by the thickness of parts: if it does not exceed 1 ... 1,5 mm then the flanging of edges is performed, if the thickness to 5 mm 0 one-sided cutting, for thicker workpieces X-shaped preparation is obligatory;
• Edges, in addition to scraping, also subjected to treatment in a concentrated sulfuric acid, which is most qualitatively removes all greasy dirt;
• Only well dried workpieces should be welded;
• Supply of argon in the area of weld formation should be carried out with a flow of not less than 100 ... 110 ^dm3/ h per 1 mm of weld, weld formation itself is desirable to perform a burner, the nozzle of which is perpendicular to the welded surfaces.

Welding fluxes

For quality welding requires the use of special welding flux, which prevent oxygen in the area of formation of the weld. Brass wire made of alloys containing a high percentage of silicon is more commonly used as filler material. As a result, not only the strength properties are increased, but also the burnout of zinc is excluded. For the same purpose, electric welding uses a "short arc", not more than 15 mm long, with a voltage not exceeding 25 V.
