Abstract
The effects of different pulse frequency on the tensile strength,bending properties and micro-hardness of the A6N01 aluminum alloy welded joints were investigated in this paper.The results showed that the welded joints at fx=1 Hz had the highest mean value of the tensile strength and the highest strength coefficient,and the welded joints at fx=0 Hz had the highest mean value of the elongation and strength-ductility balance and the best comprehensive strength and toughness.But the effect of different pulse frequency on the micro hardness of the welded joints was not obvious.Hence the weld joints had the best combination properties when the pulse frequency was 0 Hz.关键词
