I’m playing around making little thing out of stuff I have laying around.From my little experience, wire feed welding is difficult on small thin metal.I’ve switched over to brazing, which gives me more control with the amount of heat.Thats my opinion and it’s limited at best.

For steel sculptures, I would recommend learning MIG welding. It’s practical for joining steel parts and provides strong joints when done correctly. Brazing can also work for smaller decorative pieces, depending on the design. Always use proper safety equipment and practice on scrap metal first. 🇨🇱⚙️

Mig is fairly easy to learn but your welds will probably be ugly. Mine still are.

Tig gives you better control but is harder to learn.

Just a thought, but why do you feel the need to pick one method?

The tools for these techniques aren’t that expensive these days, so why not learn several and then be able to pick the best o e for the project you want to do? Or use a couple for one project - I could see mig for building a basic structure and something like brazing or silver solder for building and adding decorative elements.

You should probably pick one to start with and learn to do that reasonably well (but it’s not like you need to get to the level of a certified welder for nuclear power plants) and then figure out the next useful one and try that - like get a multi mode welder and learn mig since it’s probably quickest and must useful to start then maybe try tig.

Learning this stuff should be half the fun!
