<p>PROBLEM TO BE SOLVED: To provide an inspection method and an inspection device of a heat exchange unit, which allow a state of a weld to be electrically inspected even when a surface of a heat exchange part is covered with a fireproof part.SOLUTION: The inspection method of a heat exchange unit includes: a first measurement step of measuring electric resistance between a first projection and a second projection selected from a plurality of projections respectively; a second measurement step of measuring electric resistance between a third projection selected from the plurality of projections and the second projection; a third measurement step of measuring electric resistance between the first projection and the third projection; and a determination step of determining a state of a weld existing between at least one of the first projection, the second projection, and the third projection and a surface of a heat exchange part on the basis of measurement results of the first measurement step, the second measurement step, and the third measurement step.</p> |
