Description

technical field

[0001] The invention belongs to the field of welding, and in particular relates to an automatic welding device for a box girder and a use method thereof. Background technique

[0002] Welding is a manufacturing technology, which is developed on the basis of modern industry to meet the needs of industrial development, and directly serves the machinery manufacturing industry. The large structural parts in many equipment are almost all welded structures. With the advancement of science and technology, the scale of production is expanding day by day, and the welded structural parts are developing towards large and super large. This requires various welding machines with higher quality, better performance and more functions for welding production.

[0003] The cross-sectional shape of the box girder is the same as that of the usual box section, and is generally composed of a cover plate, a web plate, a bottom plate and a partition. At present, there are many equ...
