Abstract Joining processes especially for metallic materials play critical roles in manufacturing industries and structural applications, therefore they are essential to human life. As a more complex technique, under-liquid joining has far-reaching implications national defense, offshore mining. Furthermore, up-to-now, the effective of metals extreme environments, such as flammable organo-solvent or arctic liquid nitrogen, is still uninvestigated. Therefore, an efficient approach urgently called for. Here we report method join different types glasses under water, seawater, alcohol liquid-nitrogen. The dynamic heterogeneity liquid-like region expansion induces fluid-like behavior ultrasonic vibration promote oxide layer dispersion metal bonding, allowing be successfully joined heat-free conditions, while exhibiting excellent tensile strength (1522 MPa), bending (2930 MPa) improved corrosion properties. Our results provide promising strategy offshore, polar, oil-gas space environments.
