heat input & cooling rate

(OP)
in AWS and ASME sec IX says that if heat input increase ,the cooling rate decrease .
my question how can i produce slow cooling rate to keep the weld material in perlite phase where it must increasing heat input to do that (by understanding from above reverse proportion

RE: heat input & cooling rate

Addition of preheat with heating pads.

RE: heat input & cooling rate

HEAT RETENTION BLANKET

use of these blanket as soon as finish welding to reduce the cooling time , the pearlite structure requirements can be achievable..

Sorry but my question was in[u] reverse proportion between heat input and cooling rate, were all them should keep in lowest.!!!
