Abstract
This invention relates to shipbuilding technique field, particular to compensation quantity overplus value method that selects corresponding value for different welding method and thickness. The determination for compensation value of different inner frame and overplus value of welding deflection comprises following steps: the contraction compensation of welding line is same for whatever manual welding, CO2 pad welding or both sides auto welding; the compensation value for unilateral contraction value relates with plate thickness and accords the thin plate thickness when thick plate butt joins with thin plate; for manual welding, CO2 fillet welding, the compensation value varieties with thickness of fillet and plate; the compensation for cargo hold, double-layer bottom intercostal floor of engineer room, floor and its reinforcement material, keel-line, and vertical baffle plate, is minus one; the compensation value of prismatic plate, bracket welding, welding deformation of engineer room double bottom when segment and inverse-building, welding deformation of engineer room big frame, relates with parameters of B, L, and H. This invention uses compensation value instead of surplus, and decreases the amend and straightening.
Description
Technical field
The present invention relates to the marine technology field, especially the compensation enlarging value determination method in the marine technology.
Background technology
The control of shipbuilding precision is to implement one of gordian technique of Modern Shipbuilding Mode, is the technical guarantee that shortens production cycle, assurance build guality, reduction shipbuilding cost etc.
At present, generally use the method that places surplus to implement precision control both at home and abroad, placing surplus is exactly to stay 50mm or more surplus in the termination of member such as plate, vertical bone etc., measures after the processing, according to theoretical size unnecessary material mowing is fallen.This method is a waste material, lost labor again, and therefore, one of core technology in the precision control technology is to replace surplus with compensation rate.Yet at present domestic none cover still is fit to the compensation enlarging standard that shipyard uses, so still can't implement based on the accuracy control method of compensation enlarging.
Summary of the invention
The value standard that the objective of the invention is to determine that butt weld welding shrinkage-compensating amount places, fillet weld panel shrinkage compensation enlarging, internal framework assembling compensation enlarging, internal framework welding deformation amount places.
In order to achieve the above object, the present invention has taked following technical scheme:
The invention provides a kind of compensation enlarging value and determine method, production design is to general internal framework and internal framework welding deformation, compensation rate is zero in principle, and this compensation enlarging technology is that different welding manners, different thickness of slab are adopted the corresponding compensation amount value of placing, and definite method of different internal frameworks assembling compensation enlarging value, the internal framework welding deformation amount value of placing, comprise following several situation:
A) butt weld welding shrinkage-compensating amount
No matter be which kind of welding manner in manual welding, CO2 welding with backing, the two-sided automatic weldering, the shrinkage-compensating amount of butt weld welding is identical, and monolateral shrinkage value compensation enlarging value is only relevant with its thickness of slab, and the butt joint of thickness plate is put the shrinkage-compensating amount with the thin plate thickness of slab.Concrete value such as following table:
| Thickness of slab | Monolateral shrinkage value |
