This study investigates the impact of various welding conditions on the tensile strength of joints produced using Gas Metal Arc Welding (GMAW). The tensile strength is a critical parameter in evaluating the mechanical performance and durability of welded structures. Different welding parameters, including voltage, current, welding speed, and filler material, were systematically varied to assess their effect on the tensile strength of the welded joints. The experimental procedure involved creating a series of welds on mild steel specimens, followed by tensile testing to determine the strength of the welds. The results demonstrated a significant relationship between welding conditions and the tensile strength, with certain parameter combinations leading to enhanced joint performance. Additionally, the study analyzed the microstructure of the welds to correlate the mechanical properties with the microstructural changes. The findings provide valuable insights into optimizing welding parameters for achieving strong and reliable welds in industrial applications.

Cloud computing has revolutionized the way data is stored, processed, and accessed, offering unprecedented scalability and efficiency. However, ensuring data security and privacy in cloud environments remains a critical challenge. Homomorphic encryption has emerged as a promising solution to protect sensitive data during storage and computation in the cloud. This study explores the application of homomorphic encryption techniques to enhance security in cloud environments. By encrypting data in such a way that computations can be performed on encrypted data without decrypting it first, homomorphic encryption preserves confidentiality while enabling efficient data processing. This paper reviews recent advancements in homomorphic encryption methodologies, discusses their implementation in cloud computing, and evaluates their effectiveness in safeguarding data privacy. Practical examples and case studies illustrate the potential benefits of homomorphic encryption for securing sensitive data in cloud-based applications.
