Abstract
Official abstract text for this publication.
Provided is a submerged arc welding method for a steel plate. In welding the steel plate from an internal surface or an external surface by a submerged arc welding, welding condition is set such that, a cross-sectional area of internal weld metal S 1 and a cross-sectional area of external weld metal S 2 satisfy the formula (1), the formula (2), and the formula (3), that is, 0.40≦(S 1 +S 2 )/t 2 ≦0.80 . . . (1), S 1 /t 2 ≦0.35 . . . (2), and S 2 /t 2 ≦0.45 . . . (3), wherein t is a plate thickness of the steel plate (mm), S 1 is a cross-sectional area of the internal weld metal (mm 2 ) excluding the cross-sectional area of a portion of the internal weld metal overlapping with the external weld metal after external welding, and S 2 is a cross-sectional area of the external weld metal (mm 2 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A submerged arc welding method for a steel plate wherein, in performing internal-and-external one layer welding on a steel plate by submerged arc welding, a sum of a cross-sectional area of internal weld metal S 1 and a cross-sectional area of external weld metal S 2 satisfies the formula (1), the cross-sectional area of the internal weld metal S 1 satisfies the formula (2), and the cross-sectional area of the external weld metal S 2 satisfies the f…
