Contract review
Material grade, size, code, fabrication route and acceptance criteria.
Technology
Controlled energy. Repeatable metallurgical bonding.
Our engineering route is defined around the metal pair, geometry, final fabrication and acceptance criteria.
Process principle
A high-velocity oblique impact creates the bond
The flyer plate is separated from the base plate by a calculated stand-off. Detonation drives a progressive collision front across the assembly. A metal jet cleans the mating surfaces immediately before impact, allowing a continuous solid-state metallurgical bond to form.
The resulting interface is commonly wavy. Its geometry depends on the materials and selected process window.

Production sequence
Six controlled stages
Surface preparation
Incoming identification, flatness check and mating-surface preparation.
Assembly
Calculated stand-off, support arrangement and detonation layout.
Explosion bonding
Controlled field operation using approved process parameters.
Post-processing
Heat treatment, leveling, cutting and surface conditioning as required.
Inspection
UT mapping, mechanical tests, dimensional report and documentation.
Route selection
Explosion bonding or clad rolling?
The right route depends on alloy compatibility, dimensions, thickness ratio, quantity and end-use. Qinhai reviews both process needs and downstream fabrication before confirming supply.
