As everybody informed that HAZ is largely depend on the process and other parameter is correct but my experience HAZ in manual welding is less than 3 mm and Auto (SAW and other high heat input process) it will be less than 5 mm for carbon steel and LAS. For SS I have not observed HAZ bigger than 1 mm (we can see after etching too). I hope experienced people like Mr Kalayan can comment on statement as he might have seen many cross section HAZ after etching….. Regards. C. K.

Subject: [MW:1250] Re: HAZ There is no thumb rule for the formation of HAZ. This largely depends on welding procedure, equipment used, various consumables, electrical parameters, operators skill and the uncertainities contributed by them. Normally one should expect minimum HAZ as is it not a desirable phenomena in any welding process. ----- Original Message ----- Sent: Monday, October 27, 2008 6:53 PM Subject: [MW:1247] Re: HAZ LET ME MAKE MY QUESTION CLEAR TO YOU.
