Welding of brass with other metals and alloys
Are you interested in the technology of welding brass with other metals and alloys from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Non-removable brass joints with other metals or alloys can be made using various technologies.
Metal-arc welding
The welding process will be successful when applying a good shielding of the jet discharge. Direct polarity of the electric current is used. In this way, brass can be welded with certain types of bronze (in particular, phosphor bronze, aluminum bronze or silicon bronze). To improve the quality of the welded seam, the backing plates, made of metal / alloy that is welded with brass, are used. For welding copper-zinc alloys (brass), high values of the welding current should not be used, otherwise the zinc content will volatilize. All welding should be carried out in a flat position. If possible, the weld metal should be applied in a width that is approximately three times the width of the electrode.
Carbon arc welding
This method can be used for welding brass with steels. A filler of the same composition as the base metal is used. Metal in the carbon arc overheats, resulting in a qualitative connection.
Oxygen-acetylene welding
This technology is only possible for brass alloys, which contain a reduced percentage of zinc. The process is mainly used when connecting pipelines, since it can be executed in all positions of the parts to be welded.
Welding rods made of silicon copper or brass can be used. For oxygen welding of brass containing an increased percentage of zinc, welding rods of more refractory metals are used, the use of which is not accompanied by increased smoke evolution. Therefore, the process is carried out at an increased gas flow rate, and the flame of the burner must be set to a small excess of oxygen to help control the smoke. It may also require preheating and an additional heat source. This technology is suitable for connecting brass with copper.

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.
Gas welding using the MIG method
Gas arc welding is recommended for connecting large structures of phosphor bronze with brass. Usually direct current is used, with direct polarity and presence of protective gas (argon). The dimensions of the weld pool must be minimally permissible, and the speed of the electrode movement is as high as possible. Hot working of the finished joint reduces welding stresses and prevents cracking.
Gas tungsten arc TIG welding
Used mainly for repairing castings and joining phosphor bronze sheets. And also cast iron and steel with brass. As for gas-arc welding, it is advantageous to hot-form each layer of weld metal. By shielding the weld zone with a stream of helium or argon, either a stabilized direct current or a direct current with a reversed polarity can be used. The metal should be preheated to temperatures from 177 to 204 ° C, and the speed of electrode movement should be as high as possible.
Shielded metal arc welding
It is used for connecting brass with phosphor bronze. Direct current and direct polarity are used. The filler metal should be applied in the form of granules to obtain the best mechanical properties of the welded seam. A subsequent annealing at a temperature of 480 ° C is desirable, which increases the ductility of the weld.
