Fill a small hole in a sheet using arc welder?

[ELL]

Is this possible? I'm talking a 10mm hole. How would it be done? Thanks.

Copper or aluminium backer clamped or pressed against it as a heat sink, strike on the edge of the hole and get moving, circle round the edge then into the middle and get out before everything gets too hot and starts blowing through

If it’s a thick sheet of steel put a countersink drill deep into the hole and weld your way out. If it’s just to get rid of the hole weave over the top of it.

I just done this job myself.

Just put a different vice roughly in the same spot on 10mm thick mild steel bench top - left me two holes to "plug". Third was covered with the new vice...

Dug into hole with grinder (same idea as @8ob countersink idea - but rougher) - few weaved runs into hole with a 6013 3.2mm MMA rod - let it cool - then dug the slag inclusion out with grinder - rewelded the top - pass next to pass - no slag inclusion at top of hole - ground it back with grinder - then sanded it back with rough flap disc.

It now looks shiney - like the holes were never there.
