Embodiment 1

[0046] exist figure 1 The process block diagram of the present invention is given in , the first process is U-shaped rib groove processing, pressing, and bridge deck blanking, including: U-shaped ribs are processed with steel plates after cutting, and pressed to become U-shaped ribs ; The bridge deck is blanked with steel plates. The second process is to clean up the area to be welded and assemble the U-shaped ribs, including: clean and polish the U-shaped ribs and the welding hazards in the area to be welded on the bridge deck, and then perform U-shaped rib assembly according to the U-shaped rib assembly positioning line on the bridge deck. Rib assembly and tack welding. The third process is to weld the inner fillet weld of the U-shaped rib, and weld a fillet weld on the back of the U-shaped rib fillet weld. Devices, long-distance specification parameter adjustment control system, long-distance wire feeding system, welding video monitoring system measures. The fourth proce...

Abstract

The invention relates to an orthotropic plate U-shaped rib angle weld joint double-side welding technique. The technique relates to a groove type and an assemble gap of a U-shaped rib angle weld joint, a device capable of welding in a U-shaped rib, a remote specification parameter regulating and controlling system and a remote wire feeding system, a welding video monitoring system is adopted, a gas shielded welding wire with less splashing, stable wire feeding and less coating is adopted, and appropriate welding specification parameters are adopted. The technique plays an important role in improving the fatigue resistance of a bridge deck structure and prolonging the service life of a steel bridge. The welding equipment for internal fillet weld of a U-shaped rib, the remote wire feeding system and the welding video monitoring system in the invention are also applicable to welding of narrow structures, thus the applicability is strong.

Description

technical field [0001] The invention relates to a welding technology for U-shaped rib fillet welds of orthotropic plates, and in particular provides a welding technology for double-sided welding of U-shaped rib fillet welds of bridge decks in the manufacture of steel bridges. technical background [0002] At present, orthotropic slab structures are widely used on highway steel box girder bridges. In recent years, in order to meet the development of high-speed railways and improve the overall stiffness of the bridge deck of railway steel bridges, orthotropic deck structures have gradually been adopted on railway bridges. use. The bridge orthotropic plate structure is a structure in which a certain number of longitudinal and transverse stiffeners are welded on the deck, bottom plate or web to increase the stiffness of the bridge deck, bottom plate or web, because its stiffness is in two directions perpendicular to each other are different, resulting in structural anisotropy. ...
