welding question

thanks for the concern bob but its not just to save money its also just cause i wanna do it, and if i make some good ones you guys will be able to get them from me if you need them at a really low price. i am a pretty good welder and have welded on suspensions before in school and those people are still alive, i have fixed control arms before just not built my own completely and i used a tig then. i know a strong weld when i see it and all. the only reason i asked these questions is because a) if i had to use a tig i would have had to use my friends shop when he doesnt have anything going on where as with a mig im getting one anyway. and B) even though i know a strong weld when i see it its just safer to test these things beforehand just in case rather than risk injury to myself and someone else
