Title:
WELD STRUCTURE BODY
Document Type and Number:
WIPO Patent Application WO/2022/265010
Kind Code:
A1
Abstract:
The present invention provides a weld structure body that has excellent brittle crack arresting performance. This weld structure body: has an end face of a joined member abutted to a surface of a member to be joined that has a plate thickness of at least 50 mm; and comprises a T joint at which the joined member and the member to be joined are joined. The welded metal of the T joint has a composition comprising at least 80% austenite phase, in area%. This weld structure body can prevent the spread, to the joined member, of brittle cracks generated from a thick member to be joined, before large-scale damage occurs, by simply adjusting welding material selection or welding conditions during the welding step and, thereby, improve the safety of a boat hull structure.
