METHOD OF ASSEMBLY OF SHIP'S HULL FROM LIGHT ALLOY AND BUILDING JIG FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: shipbuilding; building ships from light alloys.

SUBSTANCE: proposed method is based on using the modules, parts and sections at increased overall dimensions as compared with their theoretical dimensions for expected welding deformation; during assembly and welding of modules of ship's hull, separate sections are turned through angle equal in magnitude and opposite is size of expected angular elastic welding deformation of ship's hull. For assembly and welding of modules, parts and units, use is made of building jig divided in two articulated sections lengthwise. Actual linear sizes of working edges of each section of building jig and distances between them are increased by magnitude of expected linear welding deformation of ship's hull. Working edges of transversal curves of each section of building jig are turned relative to respective sections of stations by angle equal in magnitude and opposite in sign to angle of expected angular elastic deformation of ship's hull.

EFFECT: enhanced accuracy of correspondence to design drawing; reduction of internal residual stresses in hull.
