if your dead set on welding it,arc weld it,2.5 mm electrode short 1 or 2 second bursts chip the slag between runs,good luck,personally i would take it off or use the kneed it
h.e,

ignore my last post,unless you can arc weld you will end up with a hole and a bigger problem

Fill the crankcase with nitrogen or CO2.

+1 for the sellys knead-it. I put the same stuff over some big holes in my gearbox about 10 months ago, still holding up all good & no oil is leaking

Just mig weld it. It wont catch fire. I have done it myself on the same motor in a Nissan van.

Go the knead it for now and then do it properly or buy a second hand sump and fix it when you have time.

if you do weld it make sure you undo the battery and you weld the earth on the sump also so you dont weld accross bearings or you can throw the whole engine away before the holliday. oil has to be drained in any case for fixing thats for sure and asclean as pissibile dont use engine degreaser however as that brakes down oil to silide particle and thats not what you want the oil pickup to be feeding after.

Welded a number of sump plug surrounds in the past, oil out, filler lid off. and away you go, watch out hot drops pf hot oil. But then again I am old guy mehanic.
