Weld Heat Affected Zone definition
Weld Heat Affected Zone definition
(OP)
On what parameters is a Heat Affected Zone defined, compliant to the ASME Codes??
Is it on the thikness like t/4 + weld width?
Is it on the weld width itself, like weld width + 1/4 of it??
Thanks to everyone!

Expect in most cases that the HAZ is going to be very narrow, probably less than 1/8"

welds?
As part of good engineering practice, we usually keep a gap of: -
Maximum of "5 times the thickness of thicker member" and "50 mm" between the two welds.
