【 摘 要 】

In this paper, WELDOX 960 high strength steel sheet was used as the research object, and the welding method was adopted with Ar-CO2 mixed gas welding method. The change of microstructure and properties under different strength matching was studied by changing the strength matching method of welded joint. The main research contents are as follows: The comprehensive mechanical properties of the weld are tested, including the tensile, impact and microhardness tests. The changes of the comprehensive mechanical properties of the welds under different strength matching are obtained, and the selection of the best strength matching under different application conditions is put forward.
