Description

Technical Field

[0001] The invention relates to the technical field of baking pan butt welding, and in particular to a butt welding device capable of automatic welding and a welding method thereof. Background Art

[0002] Butt welding is a welding technology mainly used for connecting metal materials. Butt welding is achieved by heating the contact surfaces of the two metal parts to be welded to a point close to or reaching the melting point. The heating is usually achieved by the resistance heat generated by the passage of electric current through the metal parts. During or after heating, a certain pressure is applied to the two metal parts to make their contact surfaces in close contact. Under the action of high temperature and pressure, the contact surfaces of the two metal parts undergo plastic deformation and mutual diffusion of metal atoms to form a strong welded joint. During the production process of the baking tray, the baking tray itself is processed by stamping, but the handle of the baking tray needs to be welded. Compared with other welding methods, the handle is welded by butt welding, which is fast and more convenient to operate.

[0003] In the process of butt welding the handle of a baking tray, the traditional welding method is that the worker holds the handle with one hand and supports the baking tray with the other hand. During the welding process of the butt welding equipment, the worker's hand always needs to locate the position of the handle. There are certain safety hazards in hand operation, and a large amount of smoke and harmful gases, such as carbon monoxide and nitrogen oxides, will be generated during the welding process, which will cause harm to the health of the operator.
