Caracterização microestrutural de uma junta soldada de baixo teor de carbono obtida através do processo MIG e tendo como parâmetro variável o fluxo e pressão do gás The reality of modern industry is one of constant search for the best processes that guarantee the fulfillment of growing demands, always aligning quality and productivity, as an endless cycle in search of continuous improvement. In the metalworking industry, the welding process becomes crucial and has a great influence on the product. It is a process of joining metals and is carried out from a combination of several parameters. Among the types of welding, the MIG (Metal Inert Gas) welding is one of the most commonly found in the industrial environment due to its versatility, low cost and productivity. For this, inert gas is used to protect the region to be joined, creating a barrier against possible contaminants that negatively influence the quality of the weld. The correct selection of gases and their supply flow will guarantee a process with a minimum of discontinuities. Therefore, this work aims to study the influence of shielding gas flow on MIG welding of low carbon steel boxes for industrial batteries in an industry in the interior of Pernambuco (Brazil). To this end, a comparison of the processes was carried out by varying the gas flow and comparing them from the microstructural characterization and hardness tests. The necessary results are that the use of high gas flow values, not only does not provide more protection, but they become detrimental to the process, acting in an opposite way to what was expected. In addition, a correct selection with the reduction of gas flow conferred, in addition to better quality, a reduction in material consumption and, consequently, lower costs for the process.

Projeto de um concentrador solar parabólico composto (CPC) para aplicação em dessalinizador solar no agreste de Pernambuco The use of solar collectors or concentrators for water desalination is an old technology that is present in the life of a community that suffers from long periods of drought, and has reservoirs with the concentrated presence of salts, resulting in a brackish water resource. This type of technology offers a low-cost alternative for installation, combined with simple, cheap and low-recurrence maintenance, in addition to having a negligible or non-existent cost with the daily energy supply. The present work aims to design a compound parabolic solar concentrator, to be applied in a desalinator in a city in the interior of Pernambuco, called Caruaru. The work addresses geometric factors, such as concentration ratio, parabola geometry and optical efficiency, bringing a mathematical and graphical approach to the concentrator, as well as surveys about the energy collected by the absorber tube, taking into account the characteristic losses for a CPC of Evacuated Tubes.

Desenvolvimento de modelamento cinemático inverso e aplicativo para simulação do controle de manipuladores tipo braço robótico The present work demonstrates the development of an application that enables users to perform simulations of the control of robotic arms with 3, 4, and 5 degrees of freedom through the resolution of inverse kinematics. The strategy implemented to obtain the inverse kinematic model involved geometric analysis of the robot's structure and algebraic analysis of direct kinematics, utilizing Denavit-Hartenberg concepts. The application was developed within the App Designer environment of Matlab® software. The simulations carried out in the application allow the evaluation of the robotic arm control performance in various situations, such as positioning tasks, trajectory tracking, and object manipulation. Additionally, users can input the parameters of the robotic arm, such as the number and length of the links.

Análise de viabilidade do aproveitamento da água do condensado proveniente dos ar-condicionados do bloco administrativo do IFPE - campus Caruaru Water, a natural resource of inestimable value and limited, plays a vital role in the existence and survival of humanity. Due to the frequent droughts that have occurred in recent years in Caruaru, Pernambuco, and the considerable waste of drinking water in public buildings, caused by a lack of awareness and in-depth studies to optimize the use of water, the study searches for effective approaches in wastewater management, which, without requiring high quality, can be applied to various activities, such as watering plants, cleaning external areas, floors, sidewalks, glass, among other uses. Therefore, this work aimed to carry out an in-depth study of the average production of condensed water in the refrigeration devices of the IFPE administrative block – Campus Caruaru. In view of this, a bibliographical research was carried out and subsequently estimated calculations and capture at different times on site of condensed water from two devices of different brands, to obtain the research results. This was done with the help of two thermo-hygrometers and Computer Aided Thermodynamic Tables 3 software, which through them and mathematical equations we were able to know the possible average number of liters of water that can be produced and one hour of air conditioning operation. Through these results, it was possible to discuss this work and two studies that during their development there was a large discrepancy between the amount of theoretical and collected water, giving a difference of over 20%. Given this scenario, it was possible to infer that both studies take into account that the air flow leaves the evaporator with 100% Relative Humidity, a fact that does not match reality. As evidenced in this work, the evaporator outlet sensor showed air flow with relative humidity below 100%, confirming what the psychrometric study claims. Therefore, this work brought a difference in the amount of volume stipulated and collected close to 10%, as it used data from thermo-hygrometers, thus being able to justify the difference caused by the lack of precision of thermo-hygrometers. Continuing, it was possible to estimate an average volume that can be produced by the 17 air conditioning units in the administrative block, if they are turned on during working hours, totaling more than 16 cubic meters of water per month. This volume represents approximately 20% of the monthly consumption of IFPE - Campus Caruaru. It is essential to consider not only the economic aspect, but also associate it with environmental benefits when evaluating the viability of this project, as this is the fundamental principle that guides its conception
