In multi-pass groove welding, residual stress distribution, value and associated distortion are dependent on several factors, including the welding process-dependent parameters, mechanical properties of materials and fixtures. In present study, temperature distribution of three welding processes with different geometric designs are registered by the K type thermocouple. Each of the samples contains the same thickness of stainless steel plate A316 that was welded based on welding procedure specification with gas tungsten arc welding method with groove corner joints single bevel without gap and bevel face, single and double bevel with gap and bevel face. Created residual stress on a sample was initially measured by nondestructive ultrasonic transverse waves method. After cutting the vertical part (plate without Groove), for hole drilling device installation purposes, aforementioned stress was measured by the semi-destructive hole drilling method. While for two other geometrical designs only ultrasonic method has been used to prevent parts destruction. All three aformentioned designs were modeled in Simufact.welding finite element code (FE) and results were compared with experimental temperature and residual stress measurements. The comparison shows that experimental measurements and numerical values match well with each other highlighting a reasonable validation of finite element models resutls. Current research results show that changing the geometry of the weld configuration have a significant effect on changes in the distribution and maximum value of transvers residual stress, but trivial influence on maximum longitudinal residual stress.
