Abstract

The invention discloses a double-sided forming welding process of FGB process one-sided submerged arc welding. The process comprises the steps of: S1, butt-jointing ground two to-be welded steel plates to from a groove; S2, adhering a liner; and S3, when the groove is a V-shaped groove, filling alloy powder and then covering the groove with sintered flux and when the groove is an I-shaped groove, covering the groove with sintered flux, and pulling a welding wire for submerged-arc welding for automatic primary formed welding through a submerged arc welding machine for the I-shaped groove or the V-shaped groove covered by the sintered flux, wherein the welding parameters are as follows: the welding current is 400-1200A, the welding voltage is 25-45V and the welding speed is 10-80cm / min. By improving the composition ratio of raw materials of the sintered flux, the alloy powder and the ceramic liner, different welding modes are adopted due to different thicknesses of the welded steel plates; angular deformation is effectively avoided on the basis of improvement of the welding efficiency, and the process has the beneficial effects of simple field operation and wide application range.

Description

technical field

[0001] The present invention relates to the field of welding. More specifically, the present invention relates to a FGB submerged arc single-side welding double-side forming welding process. Background technique

[0002] In the splicing construction of ship decks and curved panels, bridge steel structure decks, or other similar steel structure panel construction operations, the efficiency of panel welding is the unanimous pursuit of everyone. The use of FCB method (plane segmented assembly line) welding equipment can indeed improve the efficiency of steel plate splicing to a large extent, but this equipment is expensive and the post-maintenance cost is extremely high. Relatively low-cost twin-wire welding equipment, but most of the twin-wire welding requires steel plates to be turned over for welding, which reduces efficiency. Some positions are not suitable for turning over operations, especially in the splicing of bridge decks. More traditional artificial...
