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.
