This paper focuses on steel-aluminum welding technology and full-section vertical welding technology about large section works, mainly used in aluminum reduction.
Direct welding between steel and aluminum would easily generate brittle chemical compound and form cracks in the joints. A research shows that proper transition layer metal and wettability condition for brazing filler metal, with heat input management during welding process can effectively restrain compound formation and improve cracks tendency as well. Through numerous tests, factors that influence compound formation have been found, through which we can get good welding joints with shear strength above 110Mpa.
Considering current shortcomings of traditional repair methods about large section works during aluminum reduction, this paper also comes up with a vertical welding technology whose joints have equal property of base metal. It adapts to large section welding between steel and steel, aluminum and aluminum. Actual practise proves that it already has application condition.
