What Does HAZ Stand For?

HAZ stands for Heat Affected Zone

HAZ, or Heat Affected Zone, refers to the area surrounding a weld or heat treatment zone that experiences structural and property changes due to the application of heat. This region is critical in assessing the mechanical integrity and performance of welded components, as the heat can alter the microstructure and characteristics of the material, potentially leading to weaknesses or failure under stress. Understanding the HAZ is essential for ensuring the quality and reliability of welded joints in various engineering applications.
