Aluminum veneer welding heat-affected zone deformation correction method based on back face progressive correction

Abstract

The application discloses a kind of based on back progressive correction aluminium veneer welding heat affected deformation correction method, it is related to aluminium veneer postwelding correction technical field, the method includes: the planeness detection of aluminium veneer welded with accessory, determine the deformation area formed due to welding heat effect;According to deformation area, determine the area to be corrected on the back of aluminium veneer;First round of cold work correction is carried out to the area to be corrected from the back of aluminium veneer;The deformation area after completing first round of correction is retested;When retest result does not reach preset planeness requirement, subsequent correction amount is determined according to retest result, and next round of progressive correction is carried out to the area to be corrected from the back of aluminium veneer;Repeat retest and progressive correction until reach standard;The application is corrected by back progressive cold work, avoids the secondary influence of heat input on material performance, effectively protects the surface quality of decorative surface while recovering the planeness of aluminium veneer, and the controllability of correction accuracy is improved by the closed-loop control logic that correction amount is ladder decreasing.
