| Abstract Scope |
This paper focuses on steel-aluminum welding technology and full-section welding technology for large section works, mainly used in aluminum reduction industry.
Direct welding between steel and aluminum would easily form brittle chemical compounds and cracks. Research showed that proper transition metal as brazing filler metal, with heat input management during welding process could effectively restrain the compound formation and reduce cracks tendency. Factors that influence the compound formation have been found from numerous tests, through which we can get good welding joints with shear strength above 110 MPa.
In view of current shortcomings of traditional repair methods about large section works during aluminum reduction process, this paper comes up with a welding technology by which the joints can have equal property of the base metals. It adapts to large section welding between steel-steel, and between aluminum-aluminum. Actual practice proves that it already has fulfilled the requirements of wide application. |
