Description
A stop-action technique was used to stop tool motion during friction stir welding of aluminium alloys in order to study the interactions between the parent material and welding tool pin in the keyhole. Welds were made in 25 mm thick Al-Cu-Li 2195 plate aged to slightly under peak ageing condition. The welds were bead-on-plate welds under load control. After the emergency stop control was engaged, the plate was sectioned with the pin remaining in the centre. Samples were examined by optical microscopy and SEM. The effects of deceleration of the welding tool were considered. Four modes of pin-induced plastic work are proposed.
