Dear Sir,
Really Heat affected zone is measured regarding the micro-structure changes in the weld and also according to the experts. The theoretically calculation of HAZ may be not accurate to depend.
You can find such formula in chapter three of AWS Welding Handbook {Heat Flow in Welding}
1/Tp-To = 4.13pchY/ Hnet + 1/Tm-To;
where,
Y is width of HAZ in mm
h: plate thickness in mm
Tp is peak temperature,
To is initial plate temp (room temp or preheat temp),
pc-volumetric specific heat (J/mm3.C),
Tm is melting temp;
Hnet: net heat input (J/mm)
