Hi Laukejas:
I would not cut it with a plasma cutter; I would cut it with a portable circular saw running in a home made timber frame to guide it and with a thin kerf, anti kickback blade.
If you are going to TIG or MIG weld it, your cuts will have to be clean so you cannot lubricate the blade with anything you can't dissolve away again with acetone or some other solvent (like water!).
Best for welding if you cut dry but that may be impossible.
You may try ordinary cow's milk and then wash the aluminum thoroughly with a hose and running water...try on a test piece first.
Use your wooden sawing frame as a compression rig too, so you can close the sawn joint(s) with clamps, ready for welding.
If you're careful you won't catch it on fire.
Use the same rig with a little wooden sled for your welding rig, so the weld(s) are easier to do.
For your oven you only need 200 degrees Celsius, so ordinary building bricks loosely stacked into a long box shape and buried in a trench with sand, on top of which you can build a long charcoal firepit should work...the hardest part will be to gauge the temperature and rake the coals around to keep from overheating it in localized spots, so you have to make your trench wide enough that you can rake the coals away from the roof of the brick box if the interior is getting too hot.
Ten hours of tending the fire will be tedious, but old time potters and brickmakers did it so you can do it too.
You may have to get something that will melt at the proper temperature; Tempil sticks are the industry standard for these kinds of things, but you may not have those in Lithuania, so maybe old plastic bottles, or toothbrush bristles or something can be found that melts at the proper temperature.
Do a test run of the kiln before you put in your mast so you're sure you've learned how to control it decently.
The rest is hand work with a file to dress the weld(s) and some patience.
Cheers
