Abstract
For the higher residual stress and distortion of aluminium alloy sheet with three-dimensional curve weld,no-liner plate auto-welding was studied.The effect of current,speed,arc voltage,gas flux were investigated.The tensile performance and microstructure of joint were determined.The product with little weld distortion was manufactured.The results show that 1 .5 mm thick 5 A06 aluminium alloy three-dimen-sional curve weld can be achieved by reasonable no-liner plate CMT parameters.The weld shape is stable and uniform,tensile strength reached 347 MPa,fracture occurred in HAZ.No-liner plate CMT welding technology can be used in space curve welding for the aluminium alloy sheet.关键词
