Study on friction stir welding technology of 6082T6 aluminum alloy
Microstructure and properties of 3mm-thick 6082T6 aluminum alloy were stud-ied with friction stir welding(FSW)process parameters,namely plunge depth of shoulder,welding speed and rotation speed.The welded joints were also conducted with metallograph-ic,microhardness,tensile,and bending tests.The test results indicate the optimal parame-ters,i.e.plunge depth of shoulder,rotation speed and welding speed are 0.15 mm,1 400 r/min and 1 000 mm/min,respectively.Under this process parameter,the strength coeffi-cient of the joint weld can reach 0.82.
