Whether soldered or brazed or welded, so long as they are fused to the barrels they will "ring"
Too much emphasis is put on this ringing. Most soldered barrels are not 100% soldered the whole length and they still ring. If you want to know for sure, take a.002 shim and slide it down both sides of the ribs top and bottom and see how many places it fits. Yet these barrels will ring.
It is the ribs that are away from the barrel and won't ring as well, you will get a dull sound.
This ringing is similar to thumping a watermelon to see if it is ripe.
