You can use UpdateRecord and add a user-defined property something like /field3 set to concat( /field1, /field2 ). You can change /field3 to be whatever you want the output field name to be, and if you want to remove the other fields you can specify a schema in your Record Writer that only has the field(s) you want, such as:

{
    "type": "record",
    "name": "nifiRecord",
    "namespace": "org.apache.nifi",
    "fields": [{
        "name": "field3",
        "type": ["string", "null"]
    }]
}
