摘要：

The　hardware　of　arc　sound　acquisition　system　in　hyperbaric　underwater　MIG　welding　was　designed,　the　influence　of　different　pressure　to　voice　signal　was　studied,　and　the　microphone　was　calibrated　according　to　different　pressures.　Based　on　the　LabVIEW　software　programming,　the　arc　sound　signal,　welding　current　and　arc　voltage　during　welding　were　asynchronously　acquired　and　the　signal　feature　of　arc　sound　in　the　different　pressures　was　analyzed　both　in　time　domain　and　frequency　domain,　which　lay　the　foundation　for　the　application　of　arc　sound　signal　in　hyperbaric　underwater　MIG　welding　quality　control.　©,　2015,　Shanghai　Jiao　Tong　University.　All　right　reserved.
