3.3 Bending test

The testing of welded joints was also performed on bending, around the face, and around the root. The three-point bending test results FSW joints are given in Fig. 9. The welded FSW joint has poor bending characteristics. Comparing the obtained bending test results, the largest bend angle to the first cracking phenomenon is for welding parameters 750/116 and amounts to 42°.
