Abstract
- Highlights: [•] Effect of welding velocity and pulse frequency in GMAW of HSLA steel. [•] Dependency of weldment microstructure on the welding velocity and pulse. [•] Reduction of hardness in the weld zone and HAZ with increasing of heat input. [•] The higher strength due to the higher amount of martensite. [•] Deterioration of impact properties with formation of grain boundary ferrite. [ABSTRACT FROM AUTHOR]
