Rene:
I am in the process of MIG welding rocker panels, etc. The MIG unit is on
loan from a friend who welds for a living. He gave me the following advice
for using MIG to do spots. He also loaned me a hole punch which makes a
very clean 1/8 inch hole. Punch holes in the desired locations. Be sure
base metal is clean and smooth. Clamp the weld spot tightly, ie across the
door sill. Start the MIG point in the center on the base metal and with
small circular motion spread out to touch the top piece. Any excess weld
materials can be ground away. I have tried this on several scrap pieces and
it works great. In fact, today I will be welding the inner baffle and
rocker panels. I'll let you know my success. I'm a novice at welding, a
real test.
He also said that the inner baffle, and rocker panel joint, along the top
door opening, could be done the same. Just line up and punch holes in the
baffle and rocker at the same place and weld all three layers together. Its
a slower process than spot welding as each spot needs to be clamped very
tightly. I guess this technique can only be used when parts can be clamped
or held tightly together. He also recommended drilling and using pop rivets
to hold the parts in place and then weld for strength.
