摘要: Abstract A pinless tool design was proposed to achieve high butt tensile strength in aluminum alloy sheets (∼3 mm thick) friction stir welding (FSW), where a 7 mm long cylindrical insert rod made of tightly embedded into hollow tool. The effects diameter (d) on the properties and mechanism weld formation were investigated. For spot (FSSW), maximum rate temperature rise about 12.8 °C/s, failure load 2 kN for this (d = 10 mm), with these being 7.4 °C/s 1.35 kN plain one. FSW, 1.46 kN tool, 0.72 kN abutting edges thickness 3 mm could be welded using
