Time frequency feature extraction of the arc energy for quality detection of the aluminum alloy double pulse MIG welding

Time frequency feature extraction of the arc energy for quality detection of the aluminum alloy double pulse MIG welding

In aluminum alloy double pulse metal inert-gas (DPMIG) welding, the outputting arc current waveform is distorted under the influence of various factors such as harmonics and impact loads. The arc distortion of aluminum alloy DPMIG welding affects the arc stability and welding quality. Based on the c...
