摘要

转向架构架主要由侧梁和横梁组成,横梁与侧梁连接形式为T型接头组合焊缝形式。针对该接头形式提出MAG手工与MAG自动化焊接相结合的方式,与以往工艺相比在保证焊缝质量的前提下提高了转向架构架的生产效率,减少了返修次数及打磨量。根据工艺评定的结果确定了合理的工艺参数,该组合焊接工艺可获得满足标准和设计要求的焊缝。

Abstract

The bogie frame is mainly composed of cross beam and side beam. The joint form between cross beam and side beam studied in this paper is T Joint combined weld. According to the joint form,the way of combining MAG manual welding with MAG automatic welding is put forward,comparing with the previous process the welding efficiency is improved,the welding quality is guaranteed,and the number of rework and grinding is reduced. The reasonable process parameters are determined according to the result of procedure qualification,the combined welding process can obtain the weld that meets the standard and design requirements.
