Claims

[Scope of utility model registration request]

In a narrow gap vertical automatic welding device that performs upward welding with a contact tip protruding into the groove, a welding torch has a single or multiple cylindrical nozzle that is sufficiently larger than the inside of the groove, and a It has a shield gas ejection hole that ejects toward the bottom and an elongated shield gas ejection hole that ejects toward both sides of the groove, and a plate that slides on the inner surface of the groove so as to close the groove cross section on the lower end surface. a groove-shaped shield pipe attached with a sealing material, a welding nozzle insertion hole larger than the outer diameter of the cylindrical nozzle in the upper part, and a notch groove capable of penetrating the groove-shaped shield pipe in the lower part; a sliding plate provided with an elastic sealant on the outer edge and the inner edge of the notched groove;
The cylindrical nozzle of the welding torch is positioned in the welding nozzle insertion hole of the sliding plate, and the outer periphery of the nozzle and the welding nozzle insertion hole are connected so as to be covered with a flexible cover material, and the groove internal shield is connected. A gas shield device for automatic narrow gap vertical welding, characterized in that a pipe is airtightly fitted into the notched groove.
