南非车22E车体侧墙本地化平面度控制工艺攻关

South Africa Car body 22E Sidewall Loco Produce Flatness Control Technology Tackle

根据南非车22E车体侧墙焊接结构特点,对车体侧墙骨架分成小骨架进行组焊,并制作小骨架组焊工装,确定组焊顺序及焊接工艺规范,并提出侧墙总组焊的工艺要求,确保侧墙平面度满足设计及客户要求。

According to South Africa 22E car body sidewall assembly characteristic, divide the car body into small part to be assembly and weld, and a set of fixture is designed, make sure the assembling and welding sequences and the welding technique requirements for the small frameworks and the whole sidewall is proposed, make sure the flatness of sidewall satisfy the designer and customer request.
