This paper describes the manufacture and validation of a wet erosion testing machine. Based in norms for the erosive test and non-standardized machines reported in scientific publications analysis, a machine that responds to research and teaching needs is development. For test equipment design was considered that manufacturing cost was low and its technological simplicity in order to make manufacturing viable. A variable speed stirrer with a tool holder for coupling the sample holder was used on the manufacture of this machine. This sample holder device allows two samples of trapezoidal configuration simultaneous testing. The machine was validated by testing, under sample holder different rotational speeds. Samples of an extractor blade and samples of coatings, obtained by manual welding with a coated electrode of recharge, were tested.

Keywords : wet erosion; recharge; arc manual welding.
