Abstract
The article presents results of experimental studies of fracture toughness of the HAZ metal of low-alloy steel welded joints with different schemes of formation of a notch. Currently available methods for preparation of specimens and results of testing them to crack tip opening displacement under three-point loading were evaluated.
 
 
Keywords: manual arc welding, welded joints, fracture toughness, crack tip opening displacement fracture diagram, metallographic examinations, structure, test temperature
