Research on Friction Performance of Friction Stir Welding Tools Based on Non-Smooth Structure
In this study, based on the principles of Mask bionics, we fabricated a bionic non-smooth concave pit structure on the shoulders of friction stir welding tools and detected the thermal cycling curve, downforce, and torque of the tool in the welding process.We tested the wear loss weight and analyzed the surface morphology of the shoulder surfaces a
