Dear Antony, What do you mean from HAZ calculation? are you trying to calculate the width of HAZ? There is no such direct calculation or ready made formula available to calculate the width of HAZ, generally the width of HAZ depends on several factors. - Welding Process used, - Welding parameters / Heat input used, - Preheat / Interpass temperatures, - Material and Thickness used, etc., Hope this helps, Regards, A.Praveen Muscat If you wanted to calculate the exact width, then weld a coupon and send it your lab for macro examination, after you etch the polished specimen you'll be able to clearly see the width of the HAZ. --- On Mon, 2/7/11, antony jenis <antonyjenis@gmail.com> wrote:
