This paper introduces a new cleaner emulsion‐explosive formula and uses it in the copper/aluminum parallel plates explosive welding, with the benefits of decreasing the overall cost of emulsion explosive product and minimizing environmental pollution during use. After the welding experiment, sample's welding quality was firstly evaluated via the X‐ray tomography (XCT), optical microscopy (OM) and scanning electron microscopy (SEM). On the other hand, the energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) and X‐ray diffraction (XRD) analysis are utilized to identify the kinds of inter‐metallic compounds of samples. Our results reveal that the metal/metal interface obtained using the new emulsion explosive is more regular and wavy, and the inter‐metallic compounds, caused by rapid solidification and further cooling of the dissimilar partners, are confirmed as Al 2 Cu and AlCu.
