Recently, our company’s factory technical engineers conducted welding procedure qualification tests on steel structure products, and conducted flaw detection on the welds of the products. They not only checked the surface of the products for defects, but also assessed the capabilities of the company’s technical staff. This quality inspection was carried out in strict accordance with relevant standards and regulations, and the company’s technical staff carefully wrote on-site inspection records.
The steel structure products produced by our company are made of high-quality Q355 material. According to the different construction scales, customers can customize the specifications and models they want. The welding system of the products is in accordance with the EN1090 certification standard. The steel surface is sandblasted and derusted. Wait for treatment and the product has been preservative.
This quality inspection uses a magnetic flaw detection method to detect the welds of steel structure products. It is a method of using ferromagnetic materials to change the magnetic rate due to defects on the surface and near the surface. When magnetizing, a leakage magnetic field is generated on the surface, and magnetic powder, A method of recording and displaying defects with magnetic tape or other magnetic field measurement methods. This method not only has high sensitivity and fast speed, but also can detect defects at a certain depth on the surface. The test results show that the steel structure product meets the requirements of welding process standards and acceptance specifications, and no surface defects such as pores and cracks on the surface of the product are found. The weld is smooth and uniform, the transition between the weld bead and the base metal is smooth, welding slag and spatter Clean up.
