FRICTION STIR WELDING METHOD ENABLING A WELD ZONE TO BECOME COMPOSITE MATERIALS AND BE ALLOYED AND A COUPLING STRUCTURE USING THE SAME

摘要

PURPOSE: A friction stir welding method and a coupling structure using the same are provided to prevent the leakage of a filler material and defects in a weld zone.;CONSTITUTION: A friction stir welding method comprises the steps of: forming an insertion groove(14) on one side of welded materials(10) butte against each other, inserting a filler material to the insertion groove, attaching tape(30) to one side of the welded materials to cover the filler material, and friction-stir-welding the opposite side of the welded materials to the insertion groove, wherein the filler material is different from the welded materials and the tape is the same material as the filler material.;COPYRIGHT KIPO 2013
