Last time I checked, steel is weldable.What could be those bumps in gridded pattern?Tiedowns?The advantage of welding is they can weld anywhere, no matter how the rocket lands on the deck. Doesn't make any sense for there to need to be any special welding points on the deck when the deck is steel.

Welding in the vicinity of a tank holding residual RP-1 near valves that just went through a mach 10 re-entry seems far riskier than tie-downs that have been used for decades on aircraft carriers. Aircraft tie-downs are quick to install, reliable, and easily disengaged. Carrier decks have padeyes every 3-5 feet so landing location should not be the issue, but the scale of the first stage may make them impractical.

Imagine a scenario where you have a partially disintegrated booster on deck that needs securing and sweet RP1 spill. And would it be a lightning magnet or something?

1. Welding won't be all that risky - particularly at a fair distance from the body of the stage. This is open ocean air and you can be sure they'll go around the rocket with a portable gas monitor in any case before they start up the welder.2. I'd imagine that, having actually landed the stage on the deck, in one piece, with no damage to anyone or anything, they'd be extremely happy to weld the stage down hard - given that the alternative means there's nothing to weld at all...

(Done some heavy welding on several truck projects.)The support crew would need to quickly removed the paints around the carbon leg's pads until the metal surface is bare and clean before the oversize steel shoes is dropped over.
