The Research of Hardox400 HSLA Steels Weldability

Abstract:

This paper deals with contact to carry on tension, bend, impact toughnesss stretch and the inclined Y type ascent experiments of the Hardox400 high strength steels welding. It research weld, fusion zone and heat affected zones micro organization of Hardox400 high strength steel in making use of the optical microscope, and prepare hot temperature, weld hot importation and empress hot temperature influence weld strength, bend and impact toughness, and the weld craft parameter can be assured under physically produces condition.
