摘要
针对窄坡口管道焊接电弧跟踪的技术需求,搭建了基于高速摆动的多轴运动控制和电弧传感测控系统。基于LabVIEW的软件开发平台,开发了信号采集、滤波、偏差提取、多轴运动焊缝跟踪、起/停弧控制及人机交互程序。完成了基于CANopen协议的多轴运动控制程序开发。进行了平焊位置窄坡口短路过渡焊缝跟踪试验。试验结果表明:该测控系统可实现电流信号采集、滤波处理及偏差提取。偏差提取程序和死区PID控制策略可行有效,实现了焊缝跟踪,平焊位置最大跟踪误差为15.04%,跟踪精度为±(0.12~0.15)mm。验证了电弧跟踪测控系统各程序功能和跟踪算法的有效性。基于LabVIEW的电弧传感测控系统,编程量小,程序结构简单,能够满足窄坡口焊缝跟踪功能的理论分析和快速开发要求。
Aiming at the technical requirements of arc tracking in pipeline welding with narrow groove,a multi-axis motion control and arc sensing measurement and control system based on high speed swing was established.Based on the software development platform of LabVIEW,the programs of signal acquisition,filtering,deviation extraction,multi-axis moving weld tracking,start/stop arc control and human-computer interaction were developed.A multi-axis motion control program based on CANopen protocol was developed.The tracking test of short-circuit transition weld at narrow groove in flat welding position was carried out.The test results show that the system can realize current signal acquisition,filtering and deviation extraction.The deviation extraction program and dead-zone PID control strategy are feasible and effective,and the welding seam tracking is realized.The maximum tracking error of flat welding position is 15.04%,and the tracking accuracy is±(0.12~0.15)mm.The function of each program and the effectiveness of the tracking algorithm of the arc tracking control system are verified.The arc sensing and control system based on LabVIEW has the advantages of small programming amount and simple program structure,which can satisfy the theoretical analysis and rapid development of the tracking function of narrow groove weld.
