Background

Modern industrial science and technology are changing day by day, and especially the requirement on the application of metal materials is becoming more and more severe, and the composite board is produced in addition to the continuous progress of metallurgical technology and the requirement of modern industrial science and technology on the application of novel materials. The application of the composite plate greatly reduces the production cost of the pressure vessel pipeline and the chemical equipment industry, and the composite plate is butt joint of two dissimilar metal materials with completely different functions, so that the corresponding welding technology is different, and the requirement on welding is stricter. In the current industrial welding, a groove is firstly formed on the inner side of a rolled cylinder in most of the processing processes of the composite pressure vessel pipeline, the depth of the groove is between the joint parts of the composite plates, then the inner welding bead is welded well by using corresponding welding materials, and meanwhile, the outer welding bead is welded in succession after the inner welding is finished. However, because a certain amount of slag is generated in the welding process of the inner weld bead, the slag must be removed and cleaned to weld the outer part of the weld bead, so that the welding defect caused by the pollution of the outer part of the weld bead is avoided. In order to clean the outer part of the weld bead, an angle grinder is usually adopted to treat the outer slag in a manual grinding mode, but the cleaning mode is time-consuming and labor-consuming, and causes certain pollution to the working environment of a workshop. Meanwhile, the manual polishing force is difficult to master in place, the depth of the welding bead is shallow, the welding bead part which is welded well originally is easily thinned or worn, if the welding bead is welded outside without processing, the welding inside the welding bead is often damaged, and therefore the welding inside the welding bead is polluted, and the welding defect is caused.
