Abstract
Welding is a metal joining process that is widely used in engineering applications, such as
transportation structures, pressure vessels, steel frames, pipelines, bridges, shipbuilding, and
heavy equipment. Welding defects may occur due to several factors, including insufficient
knowledge in selecting electrode types, improper current and voltage settings, inadequate
operator welding skills, and welding positions or techniques that affect the mechanical
properties of the joint. This study aims to analyze Gas Metal Arc Welding (GMAW) on ST-37
steel joints using variations of welding groove techniques, namely straight, zig-zag, and spiral
grooves. The joint design used was a V-groove with a groove angle of 35° and a root face of 2
mm. The electrode used in this study was ER70S-6. The testing conducted in this research
included impact testing. The results showed that the highest average impact strength was
obtained from the zig-zag welding groove variation compared to the straight and spiral groove
variations.
