Title:
REPAIR/MODIFICATION METHOD FOR METALLIC SUBSTRATES
Document Type and Number:
WIPO Patent Application WO/2019/151057
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a repair/modification method for metallic substrates that is capable of reducing both defects and regions of interface in the interior of a structural body by means of modifying the arrangement deep into the interior of a structural body while preventing impurities that, for example, originate with a probe on a friction stir welding tool from being mixed into the interior of the structural body. The repair/modification method for metallic substrates pertaining to the present invention involves: a step for preparing a metallic substrate having a first region that is divided in the in-plane direction of the substrate and contains a defect and/or a structurally discontinuous part; and a step for repairing the defect and/or modifying the structurally discontinuous part by causing a probeless friction tool to be rotatingly pressed against the surface of the first region, thereby generating frictional heat while pressing on the surface.
