| titleOfInvention | Plasma arc welding method |
| abstract | The present invention provides a plasma arc welding method capable of forming a stable back bead with a high reproducibility by a simple method and capable of obtaining a good weld bead quality without occurrence of blowholes. A plasma arc welding method in which a non-keyhole welding state and a keyhole welding state are periodically changed, wherein a non-keyhole welding state is achieved by controlling a flow rate of plasma gas. The plasma arc welding method is characterized in that a plasma gas for addition is periodically supplied to the current plasma gas to instantaneously increase the pressure of the plasma gas to obtain a keyhole welding state.
