风速对机器人GMA管道焊接稳定性的影响
The Impact of Wind Speed on the Stability of GMA Pipeline Welding in Robotic Applications
摘要
Abstract
During the high-altitude GMAW process of nickel based pipelines using robots,in order to address the impact of different wind speed conditions on the stability of the gas metal arc welding process,a welding test platform with wind speed regulation function is built.Multiple sets of different wind speed conditions are set up,and the gas metal arc welding process is used to weld the pipeline.During the welding process,real-time monitoring of welding current and voltage fluctuations is carried out,and high-speed cameras and other means are used to observe changes in welding arc shape and droplet transition status in real time.The results show that when the wind speed is less than 5m/s,the influence of droplet transition stability is small,and optimizing gas protection and adjusting conventional process parameters can continue welding work;when the wind speed exceeds 10～15 m/s,the fluctuation amplitude of welding current and voltage is significantly intensified,the stability of the arc is damaged,and unstable phenomena such as skewed blowing and swaying occur,the transition of molten droplets also changes from a relatively regular pattern to a chaotic and disorderly one;when the wind speed reaches 20 m/s,the arc cannot be restarted after it has stopped,resulting in the inability to continue the welding process.Compared with existing research,a quantitative relationship between wind speed gradient and GMAW welding stability has been established,providing experimental evidence for the development of windproof processes for automated welding of high-altitude pipelines.关键词
