Abstract

FIELD: mechanical engineering; welding. SUBSTANCE: charge of explosive is placed on surface of part to be welded. At blasting of explosive oblique collision of welded part and surface of fixed part is provided, and setting clearance between parts is found from equation, where h is thickness of welded part; D is shock wave velocity in part; u is velocity of welded part metal behind leading edge of shock wave. Amount of explosive is taken to provided constant values of D and u on thickness h. EFFECT: reduced amount of explosive, decreased deformation of welded metals, improved quality of connection, provision of possibility of welding separate parts to article, connecting parts liable to fragile breakage, enlarged range of dimensions of connected parts, possibility of carrying out operations n explosion platforms and in chambers with limitation on weight of explosive.

Изобретение относится к соединению металлов сваркой и реализуется в способе сварки металлов взрывом, при этом используется уменьшенное количество взрывчатых материалов по сравнению с существующими способами, за счет этого уменьшается деформация соединяемых металлов и повышается качество соединения, создается возможность приваривать отдельные детали на изделие, соединять детали, склонные к хрупкому разрушению, расширяется диапазон размеров соединяемых деталей, соединение деталей возможно выполнять на взрывных площадках и в камерах с ограничением по весу взрывчатых веществ. Способ заключается в том, что при соединении деталей на поверхность привариваемой детали помещают заряд взрывчатого вещества, при подрыве которого обеспечивают косое соударение привариваемой детали с поверхностью неподвижной детали, а установочный зазор между деталями определяют соотношением
Figure 00000001

где h - толщина привариваемой детали, D - скорость ударной волны в этой детали, U - скорость металла привариваемой детали за фронтом ударной волны, причем взрывчатое вещество берут в количестве, соответствующем постоянству D и U на толщине h.The invention relates to the connection of metals by welding and is implemented in a method of welding metals by explosion, while using a reduced amount of explosive materials compared to existing methods, thereby reducing the deformation of the metals being joined and improving the quality of the connection, it is possible to weld individual parts to the product, to connect the parts, prone to brittle fracture, the range of sizes of parts to be joined is expanding, and parts can be joined at explosive sites and in chambers with weight restrictions for explosives. The method consists in the fact that when connecting the parts on the surface of the welded part, an explosive charge is placed, when they are detonated, they provide an oblique collision of the welded part with the surface of the fixed part, and the installation gap between the parts is determined by the ratio
Figure 00000001

where h is the thickness of the welded part, D is the speed of the shock wave in this part, U is the metal speed of the welded part behind the front of the shock wave, and the explosive is taken in an amount corresponding to the constancy of D and U over the thickness h.
