Abstract： Introduces the welding test research of S31603 + Q420qENH application of stainless steel - weathering steel clad plates for bridges currentlybeing developed inChina，including the chemicalcomposition，mechanical properties， hot processng performance tests，and weldability tests of the base material. The comprehensive mechanical properties，hot processing performance，and weldability of the S31603+Q420qEN NHsteel plate are evaluated.A welding process qualification test was conducted for the application of S31603+Q420 qENHclad plates in the Daduhe Bridge project. The -40∘C impact energy of the joint was ⩾60J ，and the joint performance was good. The welding process developed based on the welding evaluation test guided the production and manufacturing of the bridge，which has reference significance for the application of S31603+Q42OqENHclad plates in other projects.
