Mechanical behavior of austenitic stainless steel weld metals with microfissures

Mechanical behavior of all-weld-metal specimens of 308L and 316L weld with and without microfissures was evaluated by standard and pre-strain tensile testing. The test results show a similar yield strength, and a small difference on tensile strength for fissured and fissure-free 316L weld deposits. There is virtually no effect on yield and tensile strength for 308L. Microfissures in these weld metals negatively affect ductility of 316L and 308L.
