The concept of the Materials Integration (MI) has been proposed as a framework to evaluate the performance of structural materials based on the PSPP (Process, Structure, Property, Performance) linkage. In order to solve direct problems for structural materials with complex input and output, this system designs and executes a workflow that enables continuous computation while focusing on data coordination and aggregation, and aggregates data. In the second phase of our project, we will develop an Application Programming Interface (API) to drive the MI-System from external programs so that the MI-System can be used in combination with various algorithms used to solve inverse problems, such as optimization and Bayesian statistical algorithms. In addition, we aim to solve the inverse problem systematically and efficiently by developing a mechanism to effectively utilize the computational resources distributed in various places and to handle large scale computations.

“…However, nitrogen protection gas was utilized in this investigation because it had various advantageous effects on the GTAW welding of aluminum 5083. Because nitrogen has a lower specific gravity than oxygen, using nitrogen protective gas during GTAW welding on aluminum 5083 can minimize the porosity of the welded product and avoid oxygen entrapment Kunigita et al, [12] .…”

The 5xx series of Aluminium has strong corrosion resistance, excellent weldability, and good cold workability and also medium strength. This series is being utilized extensively in marine building applications for the construction of Oil tankers, pressure vessels, offshore, ships and other vessels. The purpose of this study is to verify and to ascertain how the welding process affects the corrosion rate and impact strength of 5083 Aluminium. In this experiment, four AA 5083 specimens were warmed to chosen variations of 50°C, 100°C, 150°C, 200°C, and 250°C. The amount of energy absorbed during the fracture process was then determined by subjecting the welding results to a Charpy impact test with varying loads. The best specimen was tested for corrosion rate using the Corrosion Tester 3-Electrode device after comparing impact toughness. According to the study's findings, the specimen with a 250°C preheating step had the maximum impact toughness (0.415) and corrosion rate (0.11353 mmPy).

The 5xx series aluminum alloy is currently widely used in marine construction applications for the fabrication of chemical tankers, offshore and others because it has good corrosion resistance. This study aims to determine the effect of the welding method on the corrosion rate and impact strength of 5083 aluminum. Four specimens of AA 5083 in this observation were preheated until reaching temperature 50 °C, 150 °C, 250°C and 300 oC as the selected variations. Then, welding result were tested by Charpy impact test with different load for determining amount of energy absorbed during the fracture process. After comparing the the impact toughness, the best specimen was conducting the corrosion rate test by using Corrosion Tester 3-Electrode system. The study result show that specimen with 250oC preheat was the highest impact toughness with 0.1593 mmPY corrosion rate result.
