Published: 01 February 2018
...Peyman Amirafshari; Nigel Barltrop; Ujjwal Bharadwaj; Martyn Wright; Selda Oterkus Classification societies require ship manufacturers to perform nondestructive examination (NDE) of ship weldments to ensure the welding quality of new-building ships. Ships can contain hundreds of kilometers of weld...

.... In this paper, a case study of a typical commercial shipyard, which builds a product mix of vessels is analyzed. The present state panel assembly line is mapped and then using lean tools and avantgarde technologies, such as hybrid laser arc welding, the new transformed panel assembly line is demonstrated...

...Yu-Ping Yang; Harvey Castner; Randy Dull; James R. Dydo; Dennis Fanguy A weld shrinkage prediction model was developed for thin uniform ship panels to predict in-plane shrinkage. The weld shrinkage prediction model consists of a series of empirical equations developed by analysis of shrinkage data...

...Ruth Sanderson; Bill Lucas; Roy Pocock Large sheet or thin plate steel structures invariably suffer from distortion especially when fabricated using an arc welding process. The cost of reworking in shipbuilding is high. Low-stress no-distortion (LSND) welding has been demonstrated to effectively...

...E. W. Reutzel; S. M. Kelly; M. J. Sullivan; T. D. Huang; L. Kvidahl Maturing high-power solid-state laser technology is fueling an interest in hybrid laser gas metal arc (laser-GMA) welding for shipyard fabrication activities. Hybrid laser-GMA welding has demonstrated an ability to both reduce...

...J. Dierksheide; D. Harwig; N. Evans; L. Kvidahl New ship designs are calling for complex, lightweight panels made of thinner steel (as thin as 3 mm) for weight and structure optimization. For stiffener welding on ship panels, thin steel demands small, precision fillet welds in order to reduce panel...

... the plates, the weld will create localized stress concentrations. If the welder has poor joint preparation or gas shielding, porosity can be introduced into the weld. Porosity has a significant effect on the fatigue life of the weldment. This paper brings together a collection of data on such issues...
