How to ensure the welding quality of steel structure grid?

"Welding quality directly affects the safety and service life of grid structure . In order to ensure welding quality, it is usually controlled from the following aspects: Weld detection technology: Ultrasonic testing (UT): Detect internal defects of welds, such as lack of fusion and pores. Magnetic particle testing (MT): Used to detect minor defects such as surface cracks. Radiographic testing (RT): Use X-rays to deeply detect the internal integrity of welds. Welding quality control process: Strictly control welder qualification certification. Develop a clear welding procedure qualification (WPS). Each process is inspected by quality control personnel to avoid rework. Double detection is used for key parts.
