A lump-pass welding simulation technology was developed for shipbuilding and ship repair applications based on Battelle and Caterpillar development VFT weld modeling software. To validate the efficacy of the lump-pass technology, we performed analysis on a structural configuration common to the maritime industry. The structure consisted of many longitudinal and transverse stiffeners that were welded vertically at stiffener interface locations and welded horizontally to a one-inch thick base plate. These welds included numerous multi-pass tee and butt joints. For verifying the accuracy of the lump-pass weld simulation technology, an actual structural mock-up was built with FCAW and SMAW processes. Aditonally, we performed a detailed moving arc solution to compare with the lump-pass solution of the same weld sequence to further evaluate the efficacy of the lump-pass approach. The simulation results show that the lump-pass approach is suitable for predicting weld-induced distortionin ship fabrication.
