A device for visual inspection in welded joints has been proposed, the research was oriented to demonstrate the technical advantage over conventional instruments. For this purpose, inspections were planned on standard welded specimens with the proposed device and the Cambridge, Fillet Weld, Hi-Lo, Adjustable Fillet Weld, Skew - T Fillet and Automatic Weld Size gauges. The experimental results have shown that the useful instrument, due to its geometric arrangement, presents a technical advantage with respect to the gauges studied. In fillet welding, the instrument sizes the leg and throat size in a single welding step, in groove welding the reinforcement size verification is convenient and fast, also checking the joint bevel angle, and misalignment after of the assembly. The demonstrated technical advantage has allowed the patent to be registered at INDECOPI.

Currently, we are facing an increasing demand for minerals, including gold. The benefits of gold mining in the country are reflected in its contribution to exports and tax revenues. Geometallurgy seeks to significantly reduce the impact of spatial uncertainty in mine planning because it documents the variability in a gold deposit, this minimizes the risk of the project in future exploitation. Therefore, this study raises the need for the Peruvian mining activity to implement geometallurgy in its operations and processes; to reduce the negative effects on the environment and achieve the maximum use of natural resources. The importance of geometallurgy lies in the qualification of gold deposits, based on their physical-mechanical and textural properties, process mineralogy, and chemical-metallurgical analysis. These studies provide information for conducting metallurgical leaching tests an...
