In recent decades, research on welding has grown rapidly, especially in terms of finding more efficient welding techniques. The welding angle is very important because it can affect the quality of the weld. This welding angle has been studied by many researchers. One example is an experimental study that conducted welding of HSLA steel with various angles (30°, 45°, 60°, and 90°) using ARC welding at a speed of 150 A and 10 mm/s. This study found that a smaller welding angle can improve the tensile strength and toughness of low-alloy high-alloy steel materials. This study found that the choice of welding parameters significantly affects mechanical properties, including tensile strength and toughness, which are important for applications in industries such as automotive and construction.
