What are the reinforcement welding and acceptance specifications

　　During reinforcement welding, the application scope and inspection quantity of various welding methods shall comply with the provisions in the table below.

　　Application scope and inspection quantity of reinforcement welding method

　　1. Welders engaged in reinforcement welding construction must hold welder examination certificate before they can work. (1.0.3)

　　2. All kinds of steel bars and plates to be welded shall have quality certificates; Welding rods and fluxes shall have product certificates. (3.0.5)

　　3. Before the formal welding of the project, the welders participating in the welding shall conduct the welding process test under the site conditions, and the formal production can be carried out only after passing the test. The test results shall meet the requirements of quality inspection and acceptance. (4.1.3)

　　(before the commencement of the project or the formal welding of each batch of reinforcement, no matter what welding process method is adopted, the welding process test shall be carried out under the same conditions as the production, so as to understand the welding performance of reinforcement, select the best welding parameters and master the technical level of welders responsible for production.

　　At least one group of test pieces shall be made for each brand and specification of reinforcement. If it fails for the first time, the process shall be improved and the parameters shall be adjusted The number shall be recorded for reference The test results of joint specimens (tensile / bending / shear) shall meet the requirements of quality inspection and acceptance
