Abstract: An ultrasonic detection and tensile calibration test method for bonding strength grade comprising bonding an upper substrate block to bonding groove(s) to form a theoretical bonding area, and applying a downward actual tensile force to a lower substrate block; obtaining an actual bonding area of the theoretical bonding area; calculating a first actual bonding strength by using the actual tensile force and the actual bonding area, and comparing the first actual bonding strength with a second actual bonding strength calculated to verify the correctness of the theoretical bonding area as a calibrated bonding strength; forming a bond strength table in which the theoretical bonding areas, the actual bonding areas and the first actual bonding strengths are in one-to-one correspondence; and using the actual bonding area to find the actual bonding strength corresponding to the actual bonding area from the bonding area bonding strength table.
