Abstract

This article expound 150 mm bearing plate welding process of the sea-river-through direct ship channel cable steel tower of Hong Kong-Zhuhai-Macao bridge assembly and welding technology without temporary piece clamp plate from design of beveled edges

selection of welding material

welding procedure qualification and welding process control. The feasibility and rationality of welding technology are verified by welding process evaluation test. Through welding deformation monitoring

overturning welding and nondestructive testing

the welding deformation of super thick plate is effectively controlled and the quality of welding seam is guaranteed.
