Material selection and welding process optimization for ultra thick wall header of power plant boilers
The ultra thick wall header is an essential core component of power plant boilers,responsible for multiple important roles such as heat transfer and high-pressure bearing.The quality of its materials and welding skills directly affect the safe operation and durability of the boiler.In view of the problems existing in traditional welding methods,this paper proposes a novel fuzzy control algorithm aimed at optimizing welding process parameters.The study conducted experimental verification and comparative analysis to evaluate the effectiveness of this method.Compared to traditional methods,fuzzy control algorithms have shown significant advantages in prediction accuracy and stability.The optimized welding technology using this algorithm significantly enhances the mechanical properties of the header material,such as tensile strength,yield strength,elongation,impact toughness,and hardness.At the same time,the corrosion resistance of the material has also been significantly improved.Therefore,the fuzzy control algorithm proposed in this article provides a new perspective and practical method for optimizing the welding process of ultra thick wall headers in power plant boilers.
