Topicality

It is possible to weld/solder cast iron products using brass wire and filler materials. The advantage of the process is that gas welding realizes relatively low heating temperatures of cast iron products, as a result of which the cast iron cavity retains its original structure.

How to weld cast iron using brass

The sequence of operations is as follows:

• Preparatory operations. The surface of the cast iron part is thoroughly cleaned of dirt and grease deposits. Since soldering is most often performed to restore the continuity of the part and eliminate cracks that have formed, they are pre-treated with a weak solution of orthophosphoric or sulfuric acid, then washed with water and thoroughly dried;
• Preparation of edges. Cutting edges is to obtain a unilateral bevels at angles of 20 ... 45 ° (with increasing thickness of the iron items the angle increases) or perform a ledge and deepen the destroyed area. When the thickness of the part is up to 15 mm, the width of the cutting zone is 10 ... 30 mm;

Burner position

The torch nozzle is set at an angle of 60-70° to the surface of the workpiece or component, and the filler wire is positioned at the same angle, but from the opposite side. Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Choice of mode

The choice of modes for welding cast iron with brass is carried out depending on the following factors:

• On the brand of cast iron and brass. The most universal are considered fluxes that are prepared on the basis of borax, sodium chloride and hydrochloric acid;
• Heating temperature. Cast-iron with a complex structure (malleable or modified) is desirable to weld at temperatures not exceeding 800 ... 850 °, as otherwise the brass begins evolution of hazardous to human health zinc fumes;
• From the duration of a single welding cycle. At imposition of rather short (up to 4...6 mm) welds metals do not overheat, therefore mechanical properties of a joint remain at the following level: ultimate strength, MPa - 350...400, relative lengthening, % - 10...12.

After welding and slow cooling the residual stresses in the connection area do not occur.
