Abstract
Dependence of impact strength of low-alloy weld metal on its composition and mechanical properties in tensile tests is considered. It is shown that, along with the content of main alloying elements, specific fracture energy and yield strength are the informative factors for estimation of impact strength of the weld metal.
Keywords: arc welding, low-alloy steels, weld metal, impact strength, calculation, alloying of weld metal, mechanical properties, specific energy of fracture
