Do you mean A516 gr65 and gr70[1]?

Given that these are all the same type of steel with processing limits that vary which result in the grade designations, there should be no reason why the different grades cannot be welded together. Their basic chemical compositions are the same.

Remember that when you weld the welding zone has is can no longer be considered to be normalized. The properties in that zone will be somewhat different from the bulk properties of the plate away from the weld zone.

When welding be sure to follow the procedures for A516 [1].
