Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Traditional girder manual welding process. combine figure 1 , first carry out three-sided molding assembly, and the welding sequence after three-sided molding is: a. The vertical weld between the partition and the web. Note that there should be a H / 4 at the top that is not welded temporarily; b. The partition and the lower wing c. The connection weld between the inner side of the box web and the lower wing (note that there is no welding for two meters at the hinge point); d. The connection weld between the outer side of the box web and the lower wing.

[0032] combine figure 2 , and then four-sided forming cover plate, welding sequence: a, H / 4 vertical weld between the partition and the web; b, connection weld between the partition and the upper wing; c, the inner web of the box and the The contact weld of the upper...

Abstract

The invention discloses a robot automatic welding method for a special-shaped box. The method integrates the technologies of digital welding process design, robot automatic welding, intelligent welding, welding process monitoring, welding information management and the like; the automatic welding method is used for a long and complicated crane shore bridge box girder component, and can realize automatic welding of ultra-large pieces, narrow spaces and complicated sheet structural components; and the method is suitable for three-side forming welding of port crane short bridges and clapboard assembling welding, and automatic welding of components is realized. Compared with the traditional manual welding, welding seams are uniform and consistent, the welding qualification rate is greatly improved, any polishing repair and the like are not needed after the welding is finished, the material consumption and labor cost are reduced, and the environmental pollution is reduced; and proper robotwelding parameters are adopted in the welding process.

Description

technical field [0001] The invention relates to the technical field of intelligent welding of large-scale equipment-oriented steel structure robots, and more specifically refers to a robot automatic welding method for special-shaped boxes. Background technique [0002] Large-scale hoisting machinery plays an important role in the construction of industrial facilities such as shipping, metallurgy, chemical industry, power stations, bridges, water conservancy and electric power, and is an indispensable and important mechanical equipment in the construction of national infrastructure. Among them, the large box girder structure is a key structural part in such large complex steel structure equipment. The traditional welding method adopts the manual welding method, and people have to drill into the narrow box for welding, and the FCAW welding method is used, and grinding and repairing are required after welding. The traditional welding method has problems such as backward produc...
