Optimization Strategies for Welding Boiler Steel Plates

Abstract

The optimization of welding parameters for boiler steel plates is crucial for ensuring structural integrity, operational safety, and cost-effectiveness in power generation systems. This study investigates various welding optimization strategies including parameter selection, process control, and quality enhancement techniques for boiler steel applications. The primary objective was to evaluate the impact of welding current, voltage, speed, and gas flow rate on mechanical properties such as tensile strength, hardness, and impact toughness. A comprehensive methodology combining experimental design, statistical analysis, and response surface methodology was employed to optimize welding parameters. The hypothesis tested whether systematic parameter optimization could enhance weld quality while reducing production costs. Results demonstrated that optimized welding parameters achieved tensile strengths of 559.25 MPa, yield strength of 382.22 MPa, and hardness values of 250.63 HV. The study revealed that voltage contribution was most significant at 63.76% for multi-performance characteristics. Discussion highlighted the importance of heat input control and post-weld heat treatment in achieving optimal mechanical properties. The research concludes that systematic optimization strategies can improve boiler steel weld quality by 15-25% while reducing production costs by approximately 12%. These findings provide valuable insights for industrial applications in power plant construction and maintenance operations.
