本文设计出尖状磁场约束等离子弧的装置，进行了磁场约束等离子弧的加工实验。并且研究了约束等离子弧的截面形状、弧电压等特性，分析了约束等离子弧的加工质量。
In this paper, the device of plasma arc restricted by cusp type magnetic field is designed. The machining experiments of plasma arc restricted ny magnetic field is done. We study the cross-sectional area and arc volt of the restricted ploasma arc, and then give an analysis on the machining quality of restricted plasma arc.
