The welding seam welding seam: telescopic expansion, expansion joint fixation on the elevation and retest again, to determine any deformation, does not appear in the temporary fixed bias during the process, the anchor reinforcement and pre buried reinforced welded steel beam straight on both sides at the same time, any deviation, the deformation of anchor bars and pre specific steel beam buried reinforced welded on both sides at the same time, the best time to each. If there is difficulty, the first side of weld, to install a predetermined temperature, then the other side of all welding in the welding. If there is difficulty, the first side of weld, to install the preset temperature, then on the other side. At the same time all welded connection,M ruler, flatness detection of shaped steel beams. The feeler, then at the same time, using the 3 meter ruler at any time, flatness detection of shaped steel beams. The feeler gauge flatness control in 0 ~ 1mm, ~ to avoid jumping phenomenon. In order to avoid jumping phenomenon. The number of personnel configuration to be reasonable welding, welding to try to shorten the time, all in the welding process to be removed in time after the completion of welding personnel to clamp the reasonable configuration, to try to shorten the time of welding in the welding process, all the time after removal of fixture, lifting and hanging contraction joint joint device, relax after a comprehensive quality inspection, such as inconsistentThe requirements need to be re adjusted. After completion of welding steel banding. After completion of welding steel banding.
