Sažetak
The complete procedure for the repair of fatigue damaged metal components is suggested and explained in this paper. All necessary steps are described and the most important one - the choice of the adequate fatigue crack retarding method - is supported with the fatigue test results of several fatigue crack repair methods. One group of fatigue tests deals with welding repairs as the most frequent repair procedure. The measures for fatigue strength improvements of repair weldments are described as well. Another group of specimens was tested with next fatigue crack retarding methods: metal reinforcement, CFRP patches, different crack arrest holes and tensile overloads. Structural stress factor was introduced as a crucial for the behavior of the repaired component.
