Modern industrial technology is changing with each passing day, especially the requirements for the application of metal materials are becoming more and more stringent, coupled with the continuous progress of metallurgical technology, and the demand for new material applications by modern industrial technology, composite panels came into being. The application of clad plate greatly reduces the production cost of pressure vessel piping and chemical equipment industry. Since clad plate is the butt joint of two different metal materials with completely different functions, the welding technology to be dealt with is also different, and the requirements for welding are also different. more stringent. In the current industrial welding process, most of the composite pressure vessel pipeline processing process is to make a groove on the inside of the rolled cylinder, and the depth of the groove is between the joint part of the composite plate, and then use the corresponding welding The inner bead is welded well, and the outer bead must be welded after the inner bead is welded. However, since a certain amount of slag will be generated during the welding of the internal bead, it must be cleaned before welding the outside of the bead to avoid welding defects caused by contamination of the outside of the bead. In order to deal with the cleaning of the outside of the weld bead, an angle grinder is usually used to treat the external slag by manual grinding, but this cleaning method is not only time-consuming and laborious, but also causes a certain degree of pollution to the working environment of the workshop.
