Exploring the Mechanism of Square Bars Steel for Groove Welding as Training Materials in Shielded Metal Arc Welding
Abstract:
This qualitative study explores the use of square bar steel as an alternative training material for groove welding in Shielded Metal Arc Welding (SMAW) and examines its impact on the welding skill development of Grade 12 Technical-VocationalLivelihood (TVL) students at Manticao National High School. Through in-depth interviews with experienced welders, classroom observations, and visual and nondestructive testing methods, the study investigates the interplay between welding parameters, material characteristics, and joint integrity. Findings suggest that the use of square bar steel promotes better joint precision, bevel angle formation, enhanced penetration, and reduced material waste, all of which contribute to improved weld quality. Teachers observed increased learner engagement, better alignment of welds, and greater mastery of groove and root pass welding tasks. The study underscores the potential of alternative materials in enhancing vocational instruction and highlights the need for institutional support, targeted training, and flexible curriculum adaptation to promote effective, resource-sensitive welding education.
