Theres a lot of factors and diffrent opinions when it comes down to which welding process to use when doing high SKILLED and very important structural welds like such. Seeing that i weld for a living and specialize in welding stainless, i would never use a mig on a cage. Does this mean that MIG is not up to par? No, if done right and edges beveled and welded at the correct heat and you beads tied together correctly it will work just fine. But Tig onthe other hand is a very more stable and controllable weld, plus its cleaner and quite also..just my .02

 

+1...if you are having to bondo( i thought all body men called it filler) and grind over your welds...you might need some more practice. lol

 

thats kinda what i was trying to say you can mig a cage but a tig imo looks better and is just a better weld

 

The idea that 'TIG' welds 'look better' is the fact that there is a much smaller 'HEZ' than with MIG welding.
'HEZ'= Heat Effected Zone
I'm still thinking that PROPERLY MIG welded would be the way to go in this case.
BTW, be ready to pay about $120 per point for a good welding job.
I.E. installed 8 point bar cost about $800......

 

Tinman, I agree that MIG is probably the better process in this case. Sure TIG is great, but it will end up being more costly and in the end be just as strong as a properly MIG'ed cage (key word PROPERLY). From all the cages I have seen, the weak points are more often not the welds, but the way the tubes are attached to the floor or the design itself.

 

thanks for the tips guys, looks like I will hold off on the cage for a bit... or maybe buy it and put it in later. as for the long reply, I was out of town for a while and didnt really have time to get on here.

anyway, im tossing the ideas around for big projects as I may have myself a winter beater for next to nothing coming my way, so the mustang can finally be really wrenched on, pending funding of course.

 

get the best cage and welds you can , do not put a price on such an important safety item.....if you happen to roll your car the extra money you spent will be well worth it !and the whole bondo on the welds ..good luck with that at the track.

 

Bill I picked up my cage from S & W while I was still in shippensburg, and a friend of mine and myself welded it using MIG. The cage is holding up fine and won't have a problem with passing tech.
