A Review of the Effects of Filler Rod on Bimetallic Weld Joint
Abstract: FSW (Friction Stir Welding) is a technology for joining solid-state metals. Welding metal does not melt and recast. Tunnel defects, kissing bonds, cracks, pin holes, and pipping defects are some of the most common in FSW. The defects occur as a result of poor metal mixing and insufficient heat input in the weld nugget zone. Only a small body of literature has focused on filler material and process parameters for …
