Research on a New Welding Repair Process for High Temperature Deteriorated Furnace Tube Materials
In response to the welding repair problem of high-temperature deteriorated furnace tube materials,considering the implementation difficulty of solid solution treatment process in actual repair work and the results of welding thermal simulation tests,a new process of surface remelting treatment using TIG arc is proposed.TIG arc has high power density,concentrated energy,can quickly heat and melt locally,and is low-cost and easy to operate,suitable for on-site implementation.Through TIG arc surface remelting treatment,the microstructure of furnace tube materials can be effectively improved,laying the foundation for improving the quality of welding repair.Furthermore,by combining TIG arc remelting groove treatment and overlay welding technology,welding repair comparative experiments were conducted,and through the detection and analysis of microstructure and properties,the optimal welding repair process method suitable for high-temperature service degraded transformation furnace tube materials was determined.This overcomes the limitations of on-site conditions,significantly improves the quality of welding repair,and provides a new solution for furnace tube maintenance in industrial production.
