What are the process procedures of steel structure machining and fabrication?

Steel structure is suitable for the machining and fabrication process of building steel structure, including process selection, lofting, material numbering, cutting, straightening, forming, edge processing, pipe processing, hole making, component processing and pre-assembly of steel elements. Let’s take a look at the process procedures of steel structure fabrication, as follows:

1. The design drawings provided by the architectural designer cannot be directly used for the processing and manufacturing of steel structures. However, after considering the fabrication technology, such as tolerance, machining allowance, welding control and other factors, the original design drawing of the processing drawing is drawn on this basis.

The steel structure building processing drawing is the intention of the designer and the construction personnel to communicate, which plays the role of making the essentials book, and also the actual size marking, cutting, beveling, punching, bending, assembling, welding and painting.

2. Analysis of construction conditions before production

When drawing processing drawings or reviewing design drawings, the construction conditions or degree of difficulty should be analyzed at the same time, and the parts that are difficult to weld should be carefully analyzed, whether high-strength bolts and fastening tools are used, and whether the welding angle of the electrode can be maintained in narrow places, etc.

3. Steel tape measure In engineering, any one of tape measure, wide-band steel tape measure and convex steel tape measure is mainly used. The tape measure used in the factory and the tape measure used in the field belong to the same type of product, that is, the “same ruler” is used between various types of work. If there is difficulty, the mutual difference between 10m is controlled within 0.5mm.
