Weld deformations is one of the key challenges within the welding activities at a shipyard is to cope with.
This project aims to quantify the reasons for possible weld deformation mechanisms and find solutions to minimize/eliminate these deformations to enable weight reduction by using plates with smaller thickness.
Development of predictive tools (FE-model).
Investigation and quantifications of distortions mechanisms.
Elimination/reduction of distortions by optimising welding parameters & sequence.
Development of guidelines & design rules.
Test panel distortion was successfully simulated: both qualitative & quantitative agreement resulted.
Butt welds were identified as most dominant cause for buckling.
Equivalent model gives good approximation of the lateral shrinkage and is useful for industrial (design) practice.
The results led to optimization and formulation of guidelines.
