摘要：

The　authors　analyzed　some　reasons　of　reducing　energy　input　in　welding　process　by　adopting　low-energy-input　(LEI)　welding,　through　comparing　traditional　short-circuit　transfer　to　push-pull　short-circuit　transfer.　By　using　the　self-designed　LEI　arc　welding　system　and　the　current　wave-form　control　solution,　the　authors　stated　the　relation　between　the　short-circuit　evening　current　(Ih)　and　arc　pulse　peak-value　current　(Iap),　and　analysed　the　energy　input　influenced　by　energy　distributing　during　short-circuit　period　and　arc　period.　The　paper　suggested　the　method　of　reducing　energy　input　farther　by　increasing　Ih　and　decreasing　Iap.
