The invention discloses a novel
neon gas protection explosive
welding method. The novel
neon gas protection explosive
welding method comprises the following steps that S1, cleaning is conducted, specifically, the to-be-combined surfaces of a base plate and a compound plate are cleaned up; S2, assembling is conducted, specifically, the base plate and the compound plate which are cleaned up in the step S1 are assembled according to the principle that the base plate is located on the lower portion, the compound plate is located on the upper portion, and the to-be-welded surfaces are opposite, and a gap support is placed between the base plate and the compound plate; S3, explosive and
detonator distribution is conducted, specifically, an explosive and a
detonator are distributed on the upper surface of the compound plate; S4, a
welding closed space is prepared, specifically, the base plate and the compound plate which are assembled in the step S3 are sealed through an aluminum-plastic
hot melt film, and an air exhaust / inflation port and a gas component /
pressure detection port are reserved in the
diagonal positions; S5,
neon gas is inflated, specifically, air in the
closed space in the step S4 is exhausted, and the neon gas is inflated; and S6, explosive welding is conducted, specifically, the explosive is detonated through the
detonator, and explosive welding is conducted. The situation that
metal jet flow reacts with atmospheric components, and consequently brittle products are generated can be effectively avoided and weakened, the
interface bonding quality is improved, and the welding strength is improved.
