Abstract

The invention relates to the technical field of welding devices, in particular to a welding gun. The welding gun comprises a sprayer, an air cavity, a nozzle assembly and a ball valve. The sprayer and the air cavity are connected through pipe threads. The air cavity and the nozzle assembly are connected through a connecting sleeve. The nozzle assembly and the ball valve are connected through the pipe threads. The sprayer is in a 45-degree arc shape. The nozzle assembly comprises a nozzle, an adjusting nut, a gasket, an adjusting sleeve and a joint. The nozzle is arranged at one end of the adjusting sleeve, and the joint is arranged at the other end of the adjusting sleeve. An outer thread is arranged on the outer wall of the adjusting sleeve. The adjusting nut is arranged on the outer wall of the adjusting sleeve in a sleeving mode. The gasket is arranged between the connecting sleeve and the adjusting nut. The connecting sleeve and the air cavity are connected through pipe threads. The connecting sleeve and the adjusting sleeve are connected through pipe threads. The welding gun is simple in structure and high in welding quality.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding gun. Background technique [0002] At present, in the field of welding technology, the base metal needs to be preheated or post-heated during welding, so that the quality of welding can be better. At present, there is no heating device that can realize the need to preheat or post-heat the base metal during welding. Therefore, welding after welding The overall performance of the components is not very good.
