Peculiarities of welding bronze and brass

The quality of welding of multicomponent alloys, which are both bronze and brass, is ensured by the following technological methods:

• In manual welding of such alloys, a carbon/graphitized electrode is used, the working end of which is slightly immersed in the bath with melt. Work with a short arc, when the working voltage on the electrodes should not exceed 15...20 V;
• Apply unilateral cutting of the ends of welded products, so that the formation of a bath of liquid metal is faster;
• To reduce welding time preheating of alloys is performed, and under the connecting surface put a sheet of metal with high heat capacity, such as stainless steel;
• Use additives and specialized welding fluxes.

Special electrodes

Good indicators of uniform strength of the weld between brass and bronze workpieces provides the use of special electrodes with a surface coating. Silicon bronze is used as the material of such cladding. If both alloys to be welded are multicomponent, the welding process is carried out only under a layer of flux, which eliminates the risk of overheating the alloy near the weld zone. Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at an affordable price in a wide range. Provide product delivery anywhere in the continent. The price is optimal.

Mechanical characteristics of the weld

• When welding with carbon electrodes - ultimate strength, MPa - 360 ... 400;
• When semi-automatic welding under a layer of flux - ultimate strength. MPa - 400...440;
• The same, but with use of filler wire and with preliminary heating of joined workpieces - 500 MPa.

To check the quality of connection in especially critical cases, test welding is initially performed, after which the connection area is tested for bending. Limiting angle of bending without loss of integrity of the structure and in the absence of external cracks should be no less than ¹⁷⁰⁰.
