Background
The welding of the plate is a common processing mode in the forming processing process of the plate member, the observation and detection of the welding part are indispensable steps after the welding of the plate, and especially for the plate member with high requirements on pressure property, air tightness and the like, the welding quality of the welding part is an important factor influencing the functional effect of the plate member. For example, in the process of processing, manufacturing and forming a large-scale chemical tank for storing oil gas in the chemical field, the main body structure of the tank body is a cylindrical barrel, the cylindrical barrel is generally formed by bending a thickened steel plate, and is connected with the joint position of the bent section through butt welding, in the actual welding process, no matter manual welding or automatic welding is adopted for automatic welding, the welding quality of a welding part cannot be ensured to completely meet the welding requirement due to the influence of factors such as environment and the like, so that the detection of the welding part is particularly necessary.
For welding quality detection, a nondestructive detection mode is generally preferred, and the nondestructive detection mode can specifically select ultrasonic nondestructive flaw detection or dye penetration flaw detection. The dye penetration flaw detection mainly detects welding defects such as cracks, air holes, looseness, layering, incomplete penetration, incomplete fusion and the like which are unrecognizable by naked eyes and exist at a welding position, a cleaning agent is used for cleaning the welding position during dye penetration detection, capillary penetration coloring is carried out by using a penetrating agent, then the penetrating agent on the surface is cleaned by using the cleaning agent again, finally imaging observation is carried out by using an imaging agent, and penetration development detection is carried out mainly by capillary imaging.
In the welding quality detection process for the welding part of the cylinder barrel workpiece of the chemical tank body, the existing detection process is basically finished by manpower, and the following problems mainly exist in the coloring permeation nondestructive detection by manpower:
1) When the coloring penetration detection is carried out, polishing and cleaning, cleaning by using a cleaning agent, penetrating by spraying a penetrating agent, cleaning by using a cleaning agent again and developing by spraying a developing agent are needed to be completed for the welding seam part in sequence, the whole coloring penetration detection process has more operation steps and complicated manual operation;
2) Through the manual work operation in cylinder section of thick bamboo work piece, the inner space is comparatively narrow and small, and manual operation is very inconvenient, and the butt welding seam of large-scale chemical industry jar cylinder section of thick bamboo work piece is longer, and manual detection operation is wasted time and energy, and in addition, the used reagent of coloring detection itself is flammable and explosive, and is harmful to the human body, therefore carries out manual operation in the relative confined space of cylinder section of thick bamboo work piece and has had great operational risk and strengthened the harmfulness to the human body.
