WELDING OF METAL BRIDGE SPANS
The paper deals with the development and application of a new technique of welding large steel plates of bridges. The technological procedure of this technique as applied to regular bridges. It is found that the use of a glass substrate does not significantly affect mechanical properties of both welds and metal near them. The reliability and usefulness of this technique is proved on the real bridge erected over the river Chulym. The process of balancing the residual stresses in the thermal effect zone is experimentally proved during welding work.
