Welding of bronze with brass

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

Welding of bronze with brass can be made with the help of several technologies. Brass and bronze are alloys of copper. Brass has a waxy composition of zinc, and bronze — tin as the main alloying elements. However, some bronzes contain more zinc than tin, and some contain zinc and do not contain tin. The limit of strength, hardness and plasticity of brass increases with increasing percentage of zinc.

Metal-arc welding

Brass and bronze can be successfully welded by the metal-arc method. The electrode used must be of the type of a shielded arc with a straight polarity. Brass can be welded using phosphor bronze, aluminum bronze or silicon bronze electrodes depending on the composition of the base metal and the required maintenance. For welding copper-zinc alloys, high welding current should not be used, otherwise zinc will burn out. All welding should be carried out in a flat position. If possible, the weld metal should be applied approximately three times the width of the electrode by means of a weave.

Carbon arc welding

This method can be used for welding brass and bronze with fillers having approximately the same composition as the base metal. In this process, welding is carried out almost the same way as bronze with steel. The metal in the carbon arc overheats, and this very hot metal is alloyed with the base metal in the weld zone.

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.

Oxygen-acetylene welding

This process is particularly suitable for pipelines, since it can be performed in all welding positions. Welding rods made of silicon copper or brass can be used. For oxygen welding of brass containing an increased percentage of zinc, welding rods with reduced smoke emission are used. A gas flow is required, and the flame of the burner must be slightly oxidizing in order to reduce the formation of smoke. It may also require preheating and an additional heat source.

Gas welding with a metal electrode (MIG)

The technology is recommended for connecting large structures of phosphor bronze and thick sections. Usually, a direct current, a positive electrode and a shielding gas stream, argon, are used. The melted weld pool should be small, and the speed of movement is quite high. Hot grinding of each layer reduces welding stresses and the probability of cracking.

Gas Tungsten Arc Welding (TIG)

The technology is used mainly for repairing castings and joining phosphor bronze sheets. A stabilized direct current is used, or the reverse polarity is applied by shielding the weld zone with an inert gas. The metal should be preheated to 180… 200 ° C, and the speed should be as fast as possible.

Shielded metal arc welding

Bronze electrodes coated with phosphorus are used to join bronzes. These electrodes are designed for use with direct current direct current. The filler metal should be applied in the form of granules to obtain the best mechanical properties of the welded seam. In most cases, to ensure the plasticity of the welded joint is used at a temperature of 480 ° C. The heating of the electrodes from 120 to 150 ° C) before use can be required to reduce the moisture content of the coating.
