Beschreibung
Zusammenfassung:	The invention belongs to the technical field of welding, and particularly relates to a miter gate welding device which comprises a welding gun for welding a miter gate. A gun head is fixedly connected to a port of the welding gun, a protective cover for preventing sparks from splashing is arranged on the surface of the gun head, and the protective cover is made of transparent materials. A cavity is formed in the protective cover; sparks generated in the welding process can be blocked by the protective cover so as to improve the safety in the welding process, meanwhile, inert gas can be injected from the gas inlet pipe in the welding process so that the gas can enter the cavity and then enter the protective cover from the gas inlet holes, air is lighter than the inert gas, and the safety of the welding process is improved. At the moment, inert gas can extrude air to be discharged from the air outlet groove, the end opening of the protective cover makes contact with the miter gate, air entering the protective c
