Effect of Activating Hot Dipping Aluminum Process on High Strength Steel and Aluminum Alloy Welding Properties

Article Preview

Abstract:

Technology of activating hot-dipped aluminum on high strength steel was studied, activating time and aluminizing time was also analyzed, and the optimal activating time and aluminizing time was concluded in the end. The results showed that the optimum activating treating time was 14s in this paper. At this time the degree of corrosion on steel plate surface is the most suitable for aluminizing. The proper aluminizing treating time was 14s in this experiment. In this condition, the strength of the joint could reach up to 136N/mm. Welding between activated hot-dip aluminizing steel and aluminum alloy can be got good weld joint appearance and metallurgical bonding.
