Latest Patents

Xiancheng Zhang holds a patent titled "Local heat treatment method for controlling residual stress with primary and auxiliary heating." This method involves applying a primary heating band to a weld to control its microstructure and hardness, ensuring uniformity in the structure. Additionally, an auxiliary heating band is positioned at a certain distance from the weld to generate compressive stress on the inner surface, allowing for macro-control of the compressive stress. This innovative approach eliminates the need for reinforcement with a rib plate, thereby reducing labor intensity and construction time. The method effectively minimizes deformation near the weld and redistributes the largest deformation to a non-weld zone. By carefully managing the timing between primary and auxiliary heating, the structure is enhanced while simultaneously controlling welding residual stress. The result is an optimized local heat treatment effect that generates minimal tensile or compressive stress on the inner surface of the weld.
