Features of gas welding of copper and brass

High-quality connection of these two materials is possible if the following conditions are observed:

  • Since the thermal conductivity of copper is higher than the same indicator for any brand of brass, then to increase the rate of heating of metals in the area of formation of the weld, increase the flow of flammable gas - acetylene or - more rarely - propane butane mixture. As a result, the risk of zinc vapors hazardous to life is reduced while heating the brass;
  • The burner flame must not contain atomic hydrogen, otherwise copper and zinc hydrides will form when heated. Both compounds are harmful, they increase the brittleness of metal in the weld zone, and zinc hydride is as poisonous as the vapors of this chemical element. Therefore, a strong deoxidizer is forced into the flame, which binds hydrogen and turns it into water vapor.

The burner flame control ensures that these conditions are met. Supplier Evek GmbH offers to buy domestic and foreign brass rolled products at affordable price in wide assortment. Provide delivery of products anywhere in the continent. The price is optimal.

Features of electric welding of copper and brass

High-quality welding of these materials is possible only under a layer of flux. Units should be operated at direct current, and at reverse polarity. Decrease in burn-out of zinc, which alloys brass, is eliminated by using a short arc at operating voltage of 18...20 V. In this case too under the welded parts a sheet of metal with increased heat capacity is laid (except stainless steel you can also use asbestos).

Electrode

As the electrode is used wire with protective coatings. The most common compositions of protective coatings are:

  • Manganese-silicon bronze powder;
  • Powdered aluminum on graphitized basis;
  • Ferrosilicon;
  • Refractory mineral ceramics, particularly fluorspar.
