Is post heating required for carbon steel material above 19.05mm thickness?

Answer 1

It depends on how hot it gets, but if you are talking about welding temperature then most definately.

Answer 2

Post heating is generally recommended for carbon steel material above 19.05mm thickness to reduce the risk of cracking during welding and to promote better mechanical properties. The specific post-heating requirements may vary based on the material and welding process being used. It is best to consult the specific welding procedure specifications to determine the exact post-heating requirements for the application.
