It will, but to a far lesser extent. Depending on who is doing the TIG welding. Our frames are pretty beefy anyways, so it isn't likely to be anywhere near as big of a problem as some would have you believe. Make sure if you do weld it though to avoid vertical welds, always go at an angle. Doing that reduces the chances of it cracking and failing. Just imagine if you land on a rock, and there is a small crack in your vertical weld. The next time you land on a rock, all the shcock forces are able to travel straight up the established crack, right up the weld and cause a failure. With an angled weld, the upward force can't tavel the weld as easily. The method I would recommend is for someone to just come out and make a belly pan with attached sliders. That way it bolts up nicely and if you damaged a slider, it can be worked on with no vehicle down time and you wouldn't have to cut it off of the frame. If you are wheeling hard enough to need sliders, then you are wheeling hard enough to need a better skidplate too
