For example, in the process of manufacturing and forming a large-scale chemical tank for storing oil, liquid and gas in the chemical field, the main body structure of the tank body is a cylindrical cylinder, the cylindrical cylinder is formed by bending and rolling thickened steel plates generally, and is connected with a joint of a bent and rolled section bar through butt welding, and in the actual welding process, no matter manual welding or automatic welding is adopted for automatic welding, because the welding quality is influenced by factors such as environment and the like, the welding quality of a welding part can not be ensured to completely meet the welding requirement, so that the detection of the welding part is particularly necessary.
For welding quality detection, a nondestructive detection mode is generally preferred for detection, and an ultrasonic nondestructive detection mode or a dye penetrant flaw detection mode can be specifically selected for the nondestructive detection. The dye penetrant flaw detection mainly detects welding defects such as cracks, air holes, looseness, layering, incomplete penetration and incomplete fusion which cannot be identified by naked eyes at a welding part, a cleaning agent is used for cleaning the welding part during dye penetrant detection, a penetrant is used for capillary penetrant coloring, the penetrant on the surface is cleaned again through the cleaning agent, finally, development observation is carried out through a developer, and permeation development detection is mainly carried out through capillary development.
