To piggy back on Bruce's questions about his sill/castle/rocker panel
replacement, I too have a few Q's.
I am not only replacing the full sill/castle/rocker panel setup on both
sides, I'm also replacing the floor.
Should I weld the floor in first then the sill/castle/rockers or
vis-a-versa? Also, I am thinking of spot welding the sill/rocker/castle
section together first then weld the whole thing to the body. Would this be
a bad thing or should I just stick to welding each part in one at a time?
Lastly, has anybody had marginal success with avoiding burning holes in the
metal while MIG welding them. I have several books that say the "trick" is
it a matter of setting the speed of the wire and the voltage properly. But,
I just have not been able to find that "Welding for Dummies" or "Welding
Tips and Tricks" books that seem so prevelent in other subjects at the
bookstores. I have had mixed results with various similar settings on the
voltage and wire setting. I would like to avoid additional panel purchases
if I can. Should I guestimate the drag speed of the weld, like five seconds
for every inch, then adjust timing, wire and voltage from that point, or is
it a matter of spacing between the butt ends (e.g., no spacing will reduce
putting holes in the metal)?
Thanks for any help,
