摘　　要：为保证下筒节焊缝见证件辗平后的力学性能与母材一致,在辗平后进行了不同温度恢复母材力学性能的消应退火处理。通过进行力学性能试验,找出合适的恢复母材力学性能消应退火温度。In order to ensure that mechanical property of the weld test plate can be accorded with base metal after flattening, the relief annealing treatments to recover base metal mechanical property at different temperatures were done. The proper annealing temperature was found through mechanical property tests.
