Technical Field
[0001] The utility model belongs to the technical field of weld detection, in particular to a pressure vessel weld detection pretreatment tool. Background Art
[0002] As a basic manufacturing process and technology, welding is widely used in various fields such as industrial mechanical processing. The quality of the weld has an impact on the reliability and safety of the welded structure during use. However, due to the existence of welding defects, the weld may have problems such as cracks, pores and incomplete penetration.
[0003] At present, pressure vessels usually need to be inspected for welds after welding to ensure that the pressure vessels can be used stably, and the welds need to be pretreated before inspection. The existing pretreatment is usually for staff to simply rinse the welding surface. This method cannot effectively clean the residue, and a lot of debris will still remain on the surface, which can easily lead to inaccurate data during inspection, affecting the overall quality of the pressure vessel. Utility Model Content
[0004] The purpose of the utility model is to provide a pressure vessel weld inspection pretreatment tool. By setting a cleaning component, the residue on the surface of the pressure vessel shell can be brushed, and the cleaning liquid leaked during the brushing process can wash away the dust and debris brushed on the surface of the pressure vessel shell, thereby improving the cleaning effect and making the data more accurate during subsequent inspections. This solves the problem that the existing manual flushing cannot effectively clean up the residue, and a lot of debris will still remain on the surface, which makes it easy to have inaccurate data during inspections.
