The experimental data of fracture toughness of the types 22K, 19MN5, Cresel
so 330E low carbon steels and their weldments, produced by SAW, TIC and MAW
welding methods, are presented. The greatest number of results for weldmen
ts was obtained on weld metal fabricated with YONI-13/45 and YONI-13/55 ele
ctrodes. The obtained experimental results are compared with the reference
curve of the Russian Strength Calculation Norms. (C) 1998 Published by Else
