摘要

A method of fitting an impingement plate (5) is disclosed, the impingement plate (5) being brazed to a platform (2) of a guide blade (1) of a gas turbine. The impingement plate (5) is first fastened at individual spots by spot welds (7) to at least one supporting surface (10) of the platform (2) and is then brazed at the supporting surface (10) to the platform (2). The impingement plate (5) is prefabricated with recesses (8) and the spot welds (7) are executed at the recesses (8).
