摘要：

A　generating　device　of　transverse　rotating　magnetic　field　with　high-frequency　modulation　was　designed.　Carrier　wave　and　modulating　wave　with　high　frequency　were　used　to　control　the　exciting　current　and　frequency　respectively.　The　magnetic　field　was　applied　to　tungsten　inert-gas　arc　welding　in　order　to　drive　the　arc　rotate.　For　austenitic　stainless　steel　0Cr18Ni12Mo2Ti,　the　influence　of　magnetic　parameters　on　appearance　of　weld　was　studied.　The　characteristics　of　arc　instant　shape　in　the　magnetic　field　are　analyzed.　Based　on　acting　zone　of　the　base　metal,　the　influence　mechanism　of　rotating　magnetic　field　on　appearance　of　weld　is　discussed.　The　test　results　show　that　appearance　of　weld　is　effectively　and　simply　controlled　by　the　rotating　magnetic　field　if　magnetic　parameters　are　properly　setted,　which　can　satisfy　welding　standard　of　different　situations.
