Global Progress on Welding Consumables for HSLA Steel

Abstract

This paper reviews the global progress on welding consumables for high strength low alloy steel. The numerous aspects, such as the toughness and cleanliness of weld metal, the new removal mechanisms of impurity elements and the crack resistance of weld metal, are discussed. To meet increasing environment requirements, the fumes and life cycle assessment of welding consumables are also discussed. Finally, future trends in the development of welding consumables for high strength low alloy steel are pointed out.
