For steel with a surfacing layer or composite steel plates, is it the thickness of the base steel layer or the total thickness of the steel that determines whether post-weld heat treatment is required?

Whether heat treatment is required shall be determined in accordance with the GB150 standard; heat treatment is necessary when the thickness of the base layer reaches a certain level

Your answer is too casual; it’s common knowledge that a certain thickness at the base level requires heat treatment. So, if the thickness of the base layer does not reach the level required for heat treatment, but the thickness of the composite layer or weld-on layer combined with it does reach that level, is heat treatment still necessary in such a case?
