Claims

[Scope of utility model registration request]

The tip of the crater is formed in a cross section into a flat shape such as an ellipse or a transom shape having a long axis direction and a short axis direction orthogonal thereto, and is in thermally conductive contact with the outer periphery of the tip. A welding nozzle characterized in that a refrigerant pipe for cooling is attached to the welding nozzle.
