    螺旋縫埋弧焊管周長在線測量系統(tǒng)的應(yīng)用

    Application of On-line Measuring System for Circumference of HSAW Pipe

    • 摘要: 針對人工測量螺旋縫埋弧焊管周長測量速度慢、精度誤差大等問題，提出一種在線測量系統(tǒng)。介紹該在線測量系統(tǒng)的測量原理、結(jié)構(gòu)、功能實(shí)現(xiàn)方式和現(xiàn)場應(yīng)用情況，并分析造成系統(tǒng)測量誤差的原因。該系統(tǒng)采用非接觸測量方法，可在高焊出速度工況下實(shí)現(xiàn)對大直徑螺旋縫埋弧焊管周長的高精度在線測量，并形成周長變化趨勢。該系統(tǒng)的測量精度和測量速度均滿足實(shí)際生產(chǎn)中鋼管在線測量的要求，實(shí)現(xiàn)了螺旋縫埋弧焊管成型工位周長參數(shù)的在線實(shí)時(shí)測量。

       

      Abstract: Staying with manual measurement of circumference of the HSAW pipe are such shortcomings as slow measurement operation and big accuracy errors.Accordingly an on-line measuring system is presented here in the paper.Elaborated are the main aspects of the said system, including the measurement principle, the structure, the ways to realize the functions, and the on-the-site operation status.Also conducted is an analysis of the reasons for the measurement errors of the system.With the non-contact measurement method, the system is capable of performing on-line highprecision circumference measurement of the large-sized HSAW pipe under high-welding speed operation condition, and also indicating the circumference variation trend.The system has been up to the requirements for on-line measurement of steel tube during actual production process in terms of measurement accuracy and measurement speed, having brought about realization of real-time on-line circumference measurement at the formation station of the HSAW pipe.
