摘要

研发了一种轨道式管道全位置自动焊接装置

针对现场复杂焊接作业工况改进了密封防尘的水平/高低滑块、多维调节焊枪摆动机构、齿条式快速拆装导轨等关键机构部件的设计。使用该自动焊装置进行了多组GMAW管道自动焊接试验

获得了成熟的焊接工艺参数

并进行了宏观金相、拉伸、侧弯、冲击等测试。工艺评定结果表明

该装置可用于桥梁钢管立柱的全位置对接自动焊中。目前该装置已应用于黄陵项目现场桥梁钢管立柱对接自动焊接作业中。

Abstract

A kind of rail-type automatic all-position pipeline welding equipment was developed. Aiming at the complex welding working conditions

the designs of key mechanism parts such as horizontal and vertical sliding blocks with sealing and dust-proof function

swing mechanism of welding gun with multi-dimensional adjustment function

rack type quick disassembly guide rail were improved. By using this automatic welding equipment

many groups of automatic GMAW pipeline welding tests were carried out

the mature welding parameters were obtained

and the macro metallographic

tensile

side bending and impact tests were carried out. The results show that this developed equipment can be used in the automatic all-position butt welding of the bridge steel tubular column. At present

this equipment has been applied in the automatic butt joint welding operation of bridge steel tubular column in the Huangling project site.
