The Characteristics of Magnetic Field in Multi-Torches FCAW
다전극 FCAW의 전극 간격에 따른 자기장 특성
Abstract
In order to prevent the arc blow at the FCA welding system with multi-torches, the effects of arc length on the magnetic flux at the FCA weldment was evaluated using electro-magnetic filed analysis. Magnetic flux density around arc are slightly increased with an increase in the arc length. Based on the FEA results, the minimum distance of torches to control arc blow was established.
