Which welding is strongest?

Friction stir welding (FSW) guarantees a higher quality and strength of the welds than those obtained by conventional techniques (TIG, MIG, EBW). There are 2 types of FSW welding: butt or lap welding. The choice between these configurations depends on the application.
Our studies prove that butt welding offers a better fatigue life. Moreover, this type of welding does not present any hooking defect.
