Method for applying kraft paper instead of spot welding flash to metal explosion composite plate

The invention discloses a method for applying kraft paper instead of spot welding flash to a metal explosion composite plate, and relates to the field of metal explosion welding. The method comprises replacement of the selection of a spot welding flash material and application of kraft paper instead of spot welding flash to the metal explosion composite plate. The method comprises the steps of kraft paper cutting, drawing and folding, and explosive distribution. By replacing the spot welding flash with the kraft paper, increase of the peripheral width of the composite plate, spot welding and sticking of the flash are not required, the explosive distribution widths on both sides of the composite plate can be increased, the influence of the charging boundary effect on the welding quality of the composite plate is eliminated, the explosive welding quality is ensured, and a large quantity of rare and expensive metal composite materials are saved; the kraft paper can also be taken as an explosive frame for replaci
