How To Check The Quality of The Weld After Welding Galvanized Square Steel Pipe

After welding galvanized square steel pipes, the quality of the weld can be checked by the following methods:

1. Visual inspection: First, you can visually inspect whether the surface of the weld is smooth and whether there are cracks, bubbles, holes, and other defects. At the same time, it is also necessary to check whether the width of the weld is uniform and symmetrical and whether there is slag inclusion between the weld and the pipe wall.
2. X-ray inspection: X-ray inspection is a non-destructive inspection method that can detect whether there are defects inside the weld, such as cracks, pores, incomplete welding, and other problems. This method is usually used to detect pipes, containers, etc. with higher requirements.
3. Ultrasonic testing: Ultrasonic testing is also a non-destructive testing method that can detect defects inside the weld, such as poor welding, incomplete welding, etc. This method is suitable for the detection of various welded structures.
4. Magnetic particle testing: Magnetic particle testing is a magnetic material testing method, suitable for detecting surface and near-surface defects of welds, such as cracks, slag inclusions, etc.
5. Penetrant testing: Penetrant testing is a method of detecting small defects such as surface cracks and pores. It is usually used to detect high-demand pipes, containers, etc.
