摘要

针对转向架构架结构的复杂特点

分析焊缝成形的工艺难点

通过设计分析和试验验证

得出一种特定形状或尺寸焊缝的成形工艺

通过采用与特定形状焊缝外形相同的陶瓷垫板

实现了特定形状焊缝的MAG焊直接成形

既减少了焊接填充量

显著减少焊后打磨工作量

又避免了堆焊特定形状焊缝时频繁的起弧、收弧作业

从而提高了焊缝质量

显著提升转向架构架焊接生产效率。此项技术已在部分转向架构架生产中得到了应用和推广

具有重要意义。

Abstract

In view of the complex characteristics of bogie frame

difficulties in weld shaping process are analyzed. Through the design analysis and experimental verification

a forming process for welds with specific shape or size is concluded.Through adopting the ceramic backing with the same shape as the specific shape weld

the direct forming of specific shape weld by MAG welding is realized

which decreases the welding filler

significantly reduce the polishing workload after welding

and avoids frequently striking arc and extinguishing arc in srufacing of specific shape weld

so as to improve the quality of weld and significantly increase the welding production effi-ciency of bogie frame. This technology has been applied and popularized in some bogie frame production

which is of great significance.
