Some time when you go to a fair size car show, crawl under some of the home built, kinda rough cars and you will be surprised at the spit, baling wire assembly and welds holding them together. I'm a mediocre welder at best, but when I bought my little mig, I took a course at the local welding school. Six evenings over 3 weeks - a half hour of classroom, 2-1/2 hours of burning wire.
