Explosion welding repair method of infusible uncommon metal composite board

Abstract

An explode welding repairing method which is hard to dilute metal compound board, firstly, the thickness of hard-diluting metal board is larger than the original board material by 0.5 to 1mm, the area of board material is larger than a defect zone by 20 to 60 mm2; secondly, proceed fine polishing to the compound board at the position under epair; thirdly, put rare metals on the surface under epair, the compound board under epair is made as the lower layer of base board; fourthly, the rare metal board and a placode under epair, the enlarged supporting gas between the two boards adopts edge supporting, the gap is of 7 to 10mm and laid in parallel; fifthly, the rare metal board surface after protecting is distributed with explode evenly, the protecting layer uses lubricate resin adding thinner, the thickness of the protecting layer equals to 0.5 to 1mm; sixthly, the size of the fire point is controlled below the diameter of 15mm; seventhly, after exploding compound, the invention is level to the main material after heat process, flattening and repairing and abrasion of the connection edge.

Description

technical field [0001] The invention relates to the repair and preparation of a series of metal composite boards, in particular to the repair of defective metal composite boards by means of an explosive composite method, and belongs to the field of metal composite board manufacturing. Background technique [0002] Metal composite panels are currently widely used in petroleum, chemical, pharmaceutical, shipbuilding, electric power, metallurgy and other industries. With the continuous development of material science and equipment manufacturing technology, acetic acid, nitric acid, hydrochloric acid, urea, hydrogen peroxide, polyoxymethylene and chlorination More and more refractory rare metal composite panels are being used in strong corrosion equipment in polyethylene and other production facilities. This series of composite panels has strong corrosion resistance and high economic efficiency. Due to the high price of the clad metal of this series of composite panels, once the...

AI Technical Summary

Problems solved by technology

Due to the high price of the clad metal of this series of composite panels, once the material has a defect that affects the use of the equipment during the manufacture and use of the metal composite panel, it will be a big problem to repair, and it is likely that a small defect will cause the composite panel or The equipment is scrapped, because the vast majority of refractory rare (including precious metals and alloys) metals and ordinary steel cannot be welded and repaired by ordinary welding methods
