A sensing torch for on-line monitoring of
the gas tungsten arc welding process of
steel pipes
Abstract
Non-intrusive and real-time monitoring techniques are increasingly required
by manufacturing industry in order to detect flaws in arc welding processes.
In this work the development of an optical inspection system,for monitoring
the manual gas tungsten arc welding (GTAW) process of steel pipes,is
described.The arc plasma visible emission produced during the process was
acquired and spectroscopically analysed.Measuring the intensities of
selected argon emission lines allowed real time calculation and recording of
the axial electron temperature of the plasma.Experimental results showed
that the temperature signal varies greatly in the case of instabilities of the
weld pool that cause weld defects.A suitable algorithm,based on a
statistical analysis of the signal,was developed in order to real time flag
defective joints.It is shown that several weld defects such as porosity,
dropout,lack of fusion,solid inclusions and craters were successfully
detected in a production environment.The performances of the optical
sensor were compared with the results of state-of-the-art post-weld controls
such as x-rays and penetrating dyes,showing good agreement and thus
demonstrating the validity of this quality monitoring system.
