A research on the stability of repair-welding for a great truss under the load

In this paper, we developed the direct repair welding method without eliminating load when of great steel truss is going. According to information about process and data systematized, working for eliminate defect joint analyzing used FEM on stability result welding-repair were scientific more than last time at structure. When do did not from part so it’s necessity use any Jackie turning back. The analysis construction show that very useful in practice by then problem solved clearly perfectly efforts had consumed.
