If weld has defect like worm hole or kissing bond how to repair it?

A friction stir weld may have wormhole or kissing bond defects. In order to repair these defects, it is necessary to pass the FSW tool over the weld again.
In the case of a wormhole defect, the welding operation must be repeated while maintaining the same position. To repair a kissing bond or hooking defect, the FSW tool should be slightly offset from the initial weld. Our FSW experts will assist you in defining your welding parameters. They will also advise you throughout the process of integrating the technology, particularly for the production of prototypes.
