摘　　要：微束等离子弧焊接超薄板在工业中应用广泛,但焊接难度大、焊缝对中和焊接热输入要求高。焊接过程需要进行参数的超精细调节以获得良好的焊接质量。针对这一问题,提出了超薄板微束等离子弧焊控制系统。系统基于机器学习和Modbus通讯协议对下位机进行指令输出。利用VisualStudio 2015开发环境,设计了图像预处理模块、视觉测量模块、电流输出模块和通讯模块,实现了焊缝对中和焊接热输入的精确实时调整,改善了焊缝成型,提升了焊接质量。Ultrathin plate microplasma arc welding process is widely used in industry,but it is difficult to weld with high seam alignment and welding heat input requirements,which means hyperfine adjustment is required during welding.For this problem,a microplasma arc welding control system is proposed.The system outputs instructions to the lower computer based on machine learning and Modbus communication protocol.Image preprocessing module,visual measurement module,current output module and communication module are designed in Visual Studio 2015 to realize the accurate real-time adjustment of weld seam alignment and weld heat input,which improves the weld forming and enhances the welding quality.
