Research and Application of Seamless Flux-Cored Wires for Robotic Welding

Description: Patent: ZL202311356489.1；F/PT/PCT/2024/13746（PCT）

This invention focuses on meeting the demand for high-end welding materials in the construction of important steel structure equipment such as ships and offshore platforms in China, and conducts research on the development and application of seamless flux-cored wires for robotic welding. By precisely controlling the types and proportions of alloying elements and deoxidizing elements in the flux core powder, the problem of chemical deterioration of alloying elements and deoxidizing elements caused by high-temperature annealing has been solved. A seamless flux-cored wire for robotic welding with ultra-low diffusible hydrogen (H4) and excellent comprehensive performance has been successfully developed. This welding wire has good welding process performance and excellent mechanical properties, and can be promoted and applied in fields such as shipbuilding, marine engineering, bridges, steel structures, mechanical engineering, and pipeline engineering. It has obtained 21 authorized invention patents, published 10 papers, formulated 2 enterprise standards, and registered 2 provincial and ministerial-level achievements. The total new sales volume is about 1.79 billion yuan. The product has a broad market prospect and good economic and social benefits. The third-party scientific and technological evaluation agency commented that the overall technology of this achievement has reached the international advanced level.
