What might excessive heat during repair processes cause to metal components?

Excessive heat during repair processes can lead to distortion or alteration of material properties in metal components. When metals are subjected to high temperatures beyond their recommended limits, their microstructural characteristics can change, which affects their mechanical properties. For instance, the heat can cause a phase change in the metal, leading to softening or hardening depending on the specific type of metal and its treatment.

This alteration can result in issues such as warping, changes in tensile strength, and reduced fatigue resistance. These changes are often irreversible, meaning that once the damage is done, the performance and reliability of the component may be compromised, ultimately affecting the integrity of the overall structure. Understanding these effects is crucial for anyone involved in repair processes, ensuring that appropriate measures are taken to control temperatures during welding, cutting, or other heat-intensive repair methods.
