The specific inspection items of the steel structure spherical space frame mainly include the following five aspects. SAFS steel structure will introduce the specific details to you:
1. The first is the inspection of raw materials. Check the factory certificate, test report, etc. of the material, and you can also sample for re-inspection.
2. Ultrasonic flaw detection is mostly carried out by sampling method when testing welds. If unqualified, sampling test is required.
3. The tensile and compressive bearing capacity testing is similar to the welding seam testing. Three pieces are randomly selected from each batch for tensile and pressure testing.
4. The surface of the welded ball needs to be checked with an arc-shaped die and a steel ruler. Spot check 5% of nodes according to various specifications, and require no less than 5 pieces of each type.
5. The detection of the thinning of the wall thickness of the finished ball is similar to the detection of the surface of the welded ball, but the method used is an ultrasonic thickness gauge, and the extraction method is the same.
