How is brass welded to steel

Welding brass

Welding brass

Brass is an alloy of copper and zinc, with the color ranging from light yellow to red-yellow depending on the copper content, which is between 56% and 90%. Types of brass with a copper content of between 70% and 90% are called tombac, the designation brass for alloys with 56% to 80% copper is hardly used today.

Brass with a lower copper content is used for pipes, construction profiles or fittings, while brass with a high copper content is used for jewelry and works of art.

Brass is characterized by high strength, good formability and corrosion resistance. There are several suitable methods that one can use to weld brass. These include TIG, MIG, MAG, manual arc welding and autogenous welding. The welding processes WIG, MIG and MAG belong to the inert gas welding.

An arc burns between the electrode and the workpiece and supplies the required energy. The electrode is surrounded by a nozzle from which shielding gas emerges, which protects the arc and the seam from the outside air.

TIG and MIG are inert protective gases such as helium, argon or nitrogen, while MAG converts the gases into active gases by mixing carbon dioxide or oxygen, which combine with the materials. Another difference is the function of the electrode. With MIG and MAG, the electrode takes on two tasks: it carries current and at the same time it is welding filler, whereas the tungsten electrode with TIG does not melt.

Burning acetylene

In addition, the brass can be welded using manual arc welding. Here, too, an arc burns between the workpiece and the electrode. However, the electrode is encased and forms gases and a slag when it melts.

The gases protect the arc and the night spot, the slag has an effect Melt distortion opposite. An essential point in the instructions for oxy-fuel welding is the flame, which heats the workpiece and connects it directly or with an alloy welding wire. This flame is created by burning acetylene and oxygen.
