Abstract
The fatigue behaviour of spotwelded sheets from the steels RSt 14, St 14 ZE 25/25, St 14 ZE 75/75, St 06 Z 140 and St 06 ZF 140 was investigated. Tests with these connections under constant and variable amplitude loading were carried out in air, in a 5% NaCl-solution and under condenser water. The results are presented as endurable stresses and cycles to crack initiation. Further, from the comparison of constant and variable amplitude testing damage sums are derived.
