Abstract
Structure and impact toughness of weld and HAZ metal in steel 09G2S under conditions of primary (manufacturing) and repair arc welding are compared. Recommendations are given for selection of welding consumables, taking into account service conditions of repaired items
Keywords: low-alloy structural steel, manual arc welding, repair welding, microstructure of weld metal, microstructure of heat-affected zone, impact toughness, cold resistance, welding consumables
