Brass is alloys of copper consisting mainly of copper and zinc, and it is welded in the same general manner as copper, but because of the peculiar properties of the alloying metals zinc, it is that must receive certain variation in welding. And because of varial application as structural materials in industries, in this work the general corrosion behavior of 𝛼 – Brass (Cu – 37 Zn) alloy weldments in sulphuric acid and sodium hydroxide solution at room – temperature (298k) were also the microstructure of these weldments before and after corrosion was studied and the specimen 𝛼–Brass (Cu – 37 Zn) alloy were welded by Oxygen – Acetylene mixture with three types of filler rods, 𝛼 – Brass, 𝛼 – 𝛽 -Brass and Tin – brass. The results obtained shows that the acidic media is more aggressive than alkaline media for the three weldments.
