WELDING METHOD USING WELDING DISTORTION

摘要

PURPOSE: A welding method using welding deformation is provided to omit additional restoration operation by welding in a shape which is reversely transformed. CONSTITUTION: A first plate of first block plate members and a second plate of a second block plate member are closely arranged to be welded(A). A sagging direction between the first plate and the second plate is expected(B). The first plate and the second plate are welded by applying a welding heat in the sagging direction(C). The first plate and the second plate are individually included at the first block plate member. [Reference numerals] (A) Arranging a first plate of a first block plate member and a second plate of a second block plate member close to each other; (B) Predicting the sagging direction of the first and second plates; (C) Joint-welding the first and second plates in the sagging direction;
