Description of the Invention () The invention relates to a new method for automobile sheet metal, which is mainly a sheet metal that can only be cut to remove the smallest damage without damaging the sheet metal. A gold sheet repair method that organizes and maintains the rust prevention effect of sheet metal and is convenient and fast to process. According to the current technological progress, various construction methods are becoming more and more innovative, and the repair of automotive sheet metal is no exception. In the past, when the automotive sheet metal was damaged by collision, it was generally necessary to use an experienced and masterful sheet metal master to beat it. , M will restore sheet metal to its original state, but due to changes in industrial and commercial patterns, rising wages, insufficient labor, and lack of professionals, such a method that requires experienced personnel to perform sheet metal repair is no longer suitable. Most auto repair and repair companies use the entire panel gold and M to update the damaged parts. Although this method saves time and labor, if the damaged metal parts are difficult to disassemble, they cannot be replaced. At this time, most of the methods of “partial replacement of sheet metal” are used for repair. This method uses oxyacetylene and other tools to cut off the sheet metal at a high temperature flame and then repair a piece of metal plate that has been processed in the same shape as the original sheet metal. At this point, after welding, it is completed after spraying treatments such as grinding and anti-embroidery, but this method is also used for cutting with high temperature flame. Due to the excessively high temperature, the metal toilet fiber on the periphery of the gold toilet plate will change its metal fiber and make its properties "embrittlement". When the new metal plate body is welded again, the welded part will be exposed to high temperature again. Shadow direction, and there are quite a lot of pores on the inside and outside of the welded part of the metal plate body. Therefore, most of the cars repaired in this way, most of the sheet metal starts to embroider from the inside of the welded part very quickly. One big missing. _- 5 -_ This paper size applies Chinese National Standard (CNS) A4 (210 × 297 mm) (Please read the precautions on the back before filling this page) 470716 A7 B7 V.
