Popis: 1. Types 1, 3, and 6 weld joints fail as the result of a stress raiser imitating a crack and types 2 and 4 weld joints as a result of an angle stress raiser. The strength of types 7 and 8 weld joints is governed by the strength of the sample base metal. 2. Types 1, 3, and 6 weld joints have practically the same fatigue strength characteristics. The fatigue strength characteristics of types 2 and 5 weld joints are significantly lower than the corresponding characteristics of types 1, 3, and 6 over the whole range of lives. For types 7 and 8 weld joints the fatigue strength is practically the same but in the range of cycles from 4·104 to 106 cycles type 7 weld joint was the strongest. 3. Static test results of previously cyclically loaded samples indicate that type 7 weld joint design possesses advantages in comparison with the other types of weld joint designs.
