WebHAZ is created during the laser cutting due to more localized heat and is the closed cutting zone (see Figure 7 ). Width size of HAZ is enhanced with the increase in energy input and cutting... Web29 de mar. de 2024 · Heat affected zones can be of varying size and strength. The extent and magnitude of the HAZ is inversely proportional to the thermal diffusivity and cooling rates of the material: Where thermal diffusivity is high, the material cooling rate is high and the HAZ is small.
