Magnetic Control of Plasma Arc Welding (Report III) : On the Pressure Distribution of Plasma and its Effect on Key-Hole Action
スポンサーリンク
概要
- 論文の詳細を見る
When the cusp type magnetic field is imposed on the plasma arc, its cross section becomes oval. By this magnetic control, feasible range for key-hole welding is expanded markedly. Key-hole is, however, observed to be larger than conventional one. In order to make clear this phenomena, plasma arc pressure and pressure due to surface tension of molten metal are taken into account to determine the equilibrium key-hole diameter. Calculated value agrees with experimental results.
