| Abstract: | In this paper, based on the analysis of the component materials and the welding remains stresses,the cause of the fatigue destruction in the metal component of portal crane is studied. A fatigue_resistant method in the welding joint is presented. And the related technical process of remedial welding for the welding seam crack in the metal component is proposed. It has been proved that the proposed method is feasible in engineering practice. |
