The process specification of steel structure is the guiding technical document to ensure the quality of steel structure components processing and manufacturing, and is the basis and regulations for the implementation of operation in the process of steel structure processing and manufacturing.According to the process specification, the quality, progress and safety are effectively guaranteed.However, in the actual work, there are different understandings of the importance of art regulations. Especially when the production task is heavy and the progress is urgent, it can not be carried out in an all-round way. This should not happen. Aiming at the problem of principle, it should be thoroughly cured.

 1、 Programmatic documents mainly summarize the contents and functions of route cards, express the whole manufacturing process in the unit of process, guide the management and technical personnel to understand the whole process of products, so as to organize production and prepare process documents, so as to make operators familiar with the working relationship between the upper and lower processes. 

2、 There are two main types of guidance documents. One is to summarize its content and function in the form of process code. It is a disciplinary document, which specifies the process discipline to be observed by relevant personnel in the production process. Generally, it is prepared according to the type of work or process, such as steel structure processing code, assembly process code, welder process code, etc., and the other is summarized in the form of process specification.The content and function are the unified regulations of technical requirements in the process, which are suitable for mass production, single product or constant process. 

3、 Operational documents, one is in the form of process card, which takes the production of single part as the object, and describes the whole process in detail, which is used to guide the operation method. The process card usually includes the process characteristics, material, shape and size of parts, selection of process equipment, operation method of each process step, process assembly applied, man hour quota, etc.The other is in the form of typical process card, that is, when the products with the same or similar structure and different specifications are produced in batch, the form of typical card can be adopted (the format is similar to that of process card). 

4、 The implementation of steel structure process specification and the quality of each process of steel member processing and manufacturing are the basis to ensure the overall quality of engineering components.The quality of each process to meet the specification requirements, the first thing is to implement the process specification in every process.Therefore, the colleagues engaged in the steel structure processing system, we all attach importance to the implementation and implementation of the process specification in the process of steel member processing, to ensure the production quality of steel member processing.
