Application method of kraft paper instead of spot welding flash in metal explosive composite board

Abstract

The application method of using kraft paper instead of spot welding flash in metal explosion composite plate relates to the field of metal explosion welding. The method includes selecting materials to replace spot welding flashes and using kraft paper to replace spot welding flashes in metal explosive composite panels. The application method includes three steps: step 1 cutting kraft paper strips, step 2 drawing lines and folding, Step 3: distributing medicine; using kraft paper instead of spot welding flash, without increasing the width around the doubler board, spot welding, pasting flash, and increasing the width of medicine distribution on both sides of the doubler board, eliminating the boundary effect of charge The influence of the welding quality of the composite board ensures the quality of the explosive welding and saves a lot of rare and precious metal cladding materials; the kraft paper is dual-purpose and can also be used as a medicine frame, replacing wooden medicine boxes, saving wood funds, replacing plastic medicine boxes, and preventing environmental pollution. The invention has the advantages of simple and convenient operation, safety and environmental protection, and remarkable comprehensive economic benefits. The invention can be widely applied to the production enterprises of metal explosive welding composite boards.

Description

technical field [0001] The invention relates to metal explosion welding, in particular to a method for using kraft paper instead of spot welding burrs in a metal explosion composite plate. Background technique [0002] Boundary effect is a common problem in metal explosion welding. The existence of boundary effect greatly reduces the bonding strength and recombination rate of the joint surface of metal explosive clad plate. According to the analysis of the boundary effect of the metal explosion composite plate and its influencing factors, in order to reduce the scope and area of ​​the boundary effect area of ​​the metal explosion composite plate and the amount of area cut, and save materials, two methods can be adopted: [0003] The first way is to make the doubler plate wider than the base plate by a few millimeters to several tens of millimeters. The purpose of this is to increase the width of the explosives, thereby reducing the impact of the sparse wave at the boundary o...

Problems solved by technology

[0004] For titanium, high-grade stainless steel and other expensive doubler boards or rare metal doubler boards, it is uneconomical and wasteful to adopt the first method; in actual production, the materials purchased on the market are restricted by specifications and sizes, and the boards according to customer needs Sometimes the doubler board needs tailor welding, which will waste materials or increase the weld seam. In order to save doubler board materials and reduce costs, the second method can be adopted

[0005] The second method is to extend the charge length by pasting, welding galvanized steel sheets, and butt-joining flat steel bars around the cladding plate to eliminate the impact of the charge boundary effect on the welding quality of the cladding plate. The width of the welded plate is generally 20 —40mm, using the welding flash method to eliminate the effect of charge boundary effect is good, but the operation is relatively complicated, and the double plate will have a certain amount of deformation after welding flash, which will affect the quality of explosive welding

[0008] According to the search, there is no patent application identical to the present invention in China
