T/CI 312-2024 Evaluation method for weldability of high-strength steel used in the main structure of wind turbine units
T/CI 312-2024 Evaluation method for weldability of high-strength steel used in the main structure of wind turbine units
Basic Information
Scope
This document describes the welding suitability evaluation method for high-strength steel used in the main tower of wind turbines, including the cylinder and door frame, but excluding flanges and accessories. This document is applicable to the evaluation of the welding adaptability of high-strength steel used in the main structure of onshore and offshore wind turbine towers, as well as the evaluation of the welding adaptability of low-grade structural steel. This document is also applicable to the evaluation of the welding adaptability of materials during the material selection, supplier qualification review, or bidding stages, providing an important reference for owners and designers in selecting structural steel materials, and serving as an important basis for assessing the comprehensive capabilities of material suppliers.
