Semiautomatic welding of brass

Semiautomatic welding of brass

Are you interested in the technology of welding brass semi-automatic from the company — supplier AvecGlob? Here you will find the necessary information on this topic.

Process Features

Welding of brass with a semiautomatic device (also called the MIG process) takes place only when recovering worn or damaged ship screws and similar marine applications. To obtain the best matching color, alloys of copper with aluminum are used as welding electrodes. The use of a wire of a composition adequate to the basic material is impossible in this case, due to the high arc temperature (and zinc burnout). In the case of semi-automatic welding of brass alloys, tin bronzes can also be used, but the color of the weld will not match the color of the parts to be joined.

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.

Welding technology

Preliminary determined brand of brass, since the amount of zinc in it depends on the success of the connection method MIG. To protect the weld zone, argon, oxygen dioxide, or another inert gas is necessary. When using oxygen with acetylene, mixing should occur only during welding.

The next stage is the preparation of welding flux. The flux is mixed with water until the pasty state. Then the flux is applied to the surface of the future weld joint. The flux grade is determined by the manufacturer’s recommendations.

Further, the acetylene feed rate is regulated: the flame should have a significant amount of oxidant in the composition to form a protective coating on the brass. This is very important, since the presence of sufficient oxygen guarantees that the zinc vapor will not be released from the brass. At the same time, excess oxygen adversely affects the productivity of welding and the speed of feeding the welding wire from the feeder.

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.
