| Abstract: | FH46 low temperature steel with large thickness is often used in lifting system of wind power maintenance platform. Through weldability analysis and welding procedure qualification, effective and feasible technological measures were formulated, including selection of welding consumables and welding processes, welding heat input, pre-welding and post-welding heat treatment parameters. The results proved that the welding procedure meets the requirements of LR marine platform specification and practical experiences were accumulated for welded structures of such kind of steel for cryogenic application. |
