The safety of construction engineering has always been an issue that everyone pays attention to. Steel structure engineering is mainly installed through welding and connection. The quality of welding has an important impact on the installation safety of the entire project. How to ensure the quality of steel structure engineering processing and welding? ?
1. Steel structure engineering welding uses flux-cored welding wire, uses a large flow of CO2 gas for welding maintenance, adds CO2 to maintain the stiffness of the gas column, improves wind resistance, and forms a slag-gas joint maintenance of the welding pool.
2. Clean up the weld before welding, remove the water, oxide scale, rust and oil on the surface of the weld. Welding is performed in accordance with the parameters obtained from the welding technology appraisal. The temperature between the layers is strictly controlled during the welding process, and the removal of slag between the weld beads must be complete.
3. For the welds that are completed in stages, pre-heat treatment is required before re-welding, and post-heat treatment is performed after welding.
4. When welding, adopt a reasonable welding sequence for construction (such as two, three or four symmetrical welding).
5. Welding workers should check whether the welded components meet the specification requirements, and the next process can only be carried out after they meet the specification requirements. The welding connection quality of steel structure engineering is very important. Choosing experienced welding workers can effectively pay attention to the details of the construction and ensure that the connection quality of the overall structure can meet the standard, so that the connection of the steel structure can meet the actual requirements.
