摘要

采用机器人MAG焊方法进行平敷焊焊接试验

研究机器人MAG焊金属快速成形过程中重要焊接工艺参数对焊缝成形的影响。采用单因素试验方法

分别试验焊接电流、焊接电压、焊接速度、干伸长对焊缝成形的影响

获得了各不同工艺参数对焊缝几何尺寸(焊缝宽度、余高、熔深)的影响规律。试验结果表明

焊接电流、焊接电压、焊接速度对焊缝几何尺寸的影响显著

干伸长对焊缝几何尺寸的影响较小。通过改变各工艺参数可对焊缝几何尺寸进行微调。

Abstract

The robot MAG welding method is used for flat welding test

and the influence of the important welding parameters on the appearance of weld in the rapid metal forming process of robot MAG welding is studied. By single factor test method

the influence of welding current

welding voltage

welding speed and wire extension on the appearance of weld are tested respectively

and the influence rules of different welding parameters on weld geometry dimension（weld width

reinforcement and penetration） are obtained. The experimental results show that welding current

welding voltage and welding speed have significant influence on the weld geometric dimension

while wire extension has little influence on the weld geometric dimension. The weld geometric dimension can be adjusted slightly by changing the welding parameters.
