The strength and deformation behaviour of base metal and welded specimens have been investigated using impact tensile loading. These tests have been performed on two quenched and tempered low alloy steels of different hardness and on shielded arc weld joined with austenitic and maraging filler metals. With increasing strain rate the yield strength and UTS of all base metals and welded joints were enhanced, but no reduction of ductility resp. no change in fracture mode has been observed.
