Automatic Gap Detection in Friction Stir Welding Processes (Preprint)

Abstract

A common issue that arises when welding two plates is when a gap exists between the plates. This gap may be due to improper fixturing, imprecision in the processes used to manufacture the plates, etc. This paper develops a monitoring algorithm to detect gaps in Friction Stir Welding (FSW) processes. Experimental studies are conducted to determine how the process parameters and the gap width affect the welding process; particularly, the plunge force. The proposed monitoring algorithm examines the filtered plunge force in the frequency domain to determine the presence of gaps in FSW processes reliably.
