In the present work, its authors present the new results obtained on the creation and development of an engineering approach to the assessment of stress raisers in the metal structures of dragline excavators, convenient to be applied in the express diagnostics system to test the condition of such machines. The main result of this work is the conclusion that the value of the geometric stress concentration factor for the fillet weld of metal structures of the excavator arm EH-10/70A under working conditions can be written using the Afanasiev formula.
