The purpose of this heat treatment is to treat the welds where the tubes are connected to the tube sheet. Local heat treatment of the tube ends can be carried out using electric heating methods. It is relatively easy to treat the tube ends of floating-head and U-tube type heat exchangers, while it is more complicated for those with fixed tube sheets.
Alloy steel welding must be followed by heat treatment
