Arc welding of brass

Are you interested in the technology of arc welding of brass alloys from the supplier company AvecGlob? Here you will find the necessary information on this topic.

Process Features

Arc welding of alloys of brass is possible with the use of welding electrodes of the necessary chemical composition. Their feature is high tensile strength and high ductility.

Such electrodes can be used to join brass alloys with stainless steel and ferrous metals, including cast iron, and also form thick-walled brass gaskets from conventional sheet metal. The electrodes must meet the following requirements:

High versatility;

Insensitivity to temperature changes;

Application possibilities for diffusion transfer (metallization).

Arc welding of brass alloys is used in marine applications, as well as when connecting pipelines.

Typical parts subjected to arc welding

Cams, pumps, valves, pulleys, pistons, housings, impellers, pipes, floor plates, coils, guides, cams, legs, collectors, running and feeding screws, shafts, bearing surfaces, crosses, drive sprockets,

Mechanical Properties of Electrodes and Welding Current Modes

Ultimate tensile strength, MPa — 340;

Yield strength, MPa — 210;

Relative elongation,% — not less than 18;

Hardness according to Brinell, HB — no more than 105.

The direct polarity of the current (alternating or constant) is used, with a maximum current strength of not more than 130… 140 A.

Supplier — AvekGlob Company — offers to purchase assortment of various brass alloys of domestic and foreign production. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

Technology of arc welding of brass

Welding of brass alloys with an electric arc is performed in the following sequence. The welding zone is thoroughly cleaned of grease, scales and process greases. Preheating is only required for heavy or complex products, with the optimum temperature being 200 ° C.

When welding a short arc is supported. Before extinguishing the arc, check the completeness of filling the craters with liquid metal (pores are inadmissible). The slag formed during welding is removed by subsequent cleaning of the place of the finished joint.

For multi-pass works, it may be necessary to reduce the values of the processing current while simultaneously increasing the temperature of the base metal.

Supplier — AvekGlob Company — offers various types of products from brass alloys of domestic and foreign production, which meets the requirements of standards. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
