ASSESSING THE INFLUENCE OF WELDING CURRENT ON WELD QUALITY IN MANUAL ARC WELDING MACHINES THROUGH ULTRASONIC TESTING

Abstract

Welding is a critical manufacturing process, akin to milling, turning, and grinding, essential for producing mechanical products. The integrity and durability of welds are crucial for ensuring the quality and longevity of these products. The significant impact of selecting the appropriate welding current on the quality of welds produced by manual arc welding machines was explored by conducting experimental weld passes on various standard weld samples and employing ultrasonic testing to detect internal defects. The study aims to establish a clear relationship between welding current settings and weld quality. The findings contribute to formulating optimal welding parameters, enhancing the quality and reliability of welding in industrial applications.
