There is a weld evaluation for Q345R, but none for 16MnDR. Is it necessary to obtain a weld evaluation for a 4-mm-thick material?

If a weld assessment for 16MnDR after thickening to 4mm is to be prepared, is it necessary to carry out such an assessment? After all, 4mm test plates cannot be used for impact tests
I really don’t understand; what exactly is it that you’re asking about?
Is it necessary to use 16MnDR with a thickness of 4mm?
The two fall into the same category and group; if neither requires a shock test or both require one, they can cover each other.
All require impact testing; the temperature for the impact testing varies, and 4mm thick plates cannot be subjected to impact testing
First, tell me the thickness of the products that need to be covered
The thickness of the test plate has been taken into account; the main consideration is whether to conduct this weld evaluation
The welding materials used for these two materials are different, and the temperature conditions under which they are used are also different; how can they be substituted for one another?
It is an important factor; when the supplementary factors are the same, no further action is needed.
