Detecting Incomplete Penetration in Friction-Stir Welds with Eddy Current

Friction-stir welding is a relatively new solid-state joining process (where metal is not melted). This welding technique uses a body tool to join two facing surfaces. Heat is applied on the material, leading to a very soft region near the friction-stir welding tool. The tool spins to mechanically intermix the two facing surfaces. The softened … Continue reading Detecting Incomplete Penetration in Friction-Stir Welds with Eddy Current
