The Department of Mechanical Engineering, Amrita School of Engineering, Coimbatore campus will organize a one day Symposium on Recent Trends in Signature Analysis of ARC WELDING on March 6, 2017.

Overview of the Symposium

Welding is one of the major metals joining process employed in industries for various fabrication purposes from small scale to a mass  production. In an automated environment, developing a process monitoring and control system will ensure the weld quality and prevent the occurrence of defects. Signature analysis is the term which is used to correlate the condition of the weld and its current and voltage flow.

The signature of the current and voltage will get disturbed when a disturbance is introduced intentionally or unintentionally to the otherwise stable process leading to defective weld during the process. By monitoring and identifying the variations in the signature of current and voltage by using appropriate sensors,weld defects can be identified in real time using high speed data acquisition system. Off late, machine learning algorithms are becoming popular for developing a real-time weld monitoring system.

Objectives  of the Symposium

  • To provide an insight view on weld signature analysis using current and voltage for different arc welding processes.
  • To explore the potential of high speed data acquisition system and their applications in arc welding for process monitoring and control.
  • To have an insight on machine learning-algorithms and their capability in classifying the fault conditions

Practicing engineers from industry, Faculty members form academic institutions, Research scholars, Graduate & undergraduate students would like to pursue project work in the area of welding / signature analysis.

Interested external candidates can send the registration through email. Internal candidates are requested to register their names with organizing secretaries.

Registration fee

Mode of Payment: By cash on Spot. However registrations should be completed on or before 03.03.2017
