Strengthening and toughening mechanism of weld metal of 690 MPa-grade high-strength steel

Two different types of weld metals with a yield strength of 690 MPa were prepared. The microstructure analysis and mechanical property tests were carried out, and the strengthening and toughening mechanism of the weld metals was revealed. The results show that the nickel equivalent (Nieq) of the tra...
