Welding Process Optimization for Orthotropic Compound Bridge Plates

Article Preview

Abstract:

Compound plates of stainless steel is used to weld under construction in the Southern links railway bridge for the first time in China, but there occurs weld warpage of the convex parts and roughness appears excessive on the overall composite plate and severe deformation in the early phase of construction and the quality of railway bridge is affected seriously. Reasons of the impacting weld quality are analyzed and specific measures are proposed, and the construction program is optimized,too. A good foundation for the compound plate welding is layed and the efficiency and quality of welding can be improved .All of these will be contribute to ensure the overall quality of the welding quality of railway bridge.
