摘要
60t以上托圈分步加工然后整体组装的焊接过程中容易产生变形。制定正确的焊接工艺,就能控制焊接变形,保证托圈两耳轴的同轴度,满足托圈设计使用的技术要求。
The 60t supporting ring can be easily distorted while step machining and whole assembly.drawing up the correct welding technology can control the welding distortion,guarantee trunnion concentricity,and can meet technical requirements of Supporting Ring's design.
