Auto body repair & detailing: 1995 Jeep Cherokee Floor Pan Replacement, seam seal, jeep cherokee


Question
QUESTION: I am going to replace the floor pan in my 1995 Jeep.  I have ordered panels but am unsure how to anchor them.  I have a small welder with 2 heat settings 60 & 80 A and flux wire feeding.  The problem is the welder melts mor metal than welds.  Would body panel adhesives and rivets work?  Am I better looking for another welder that will go lower than 60 A?  Any help will be greatly appreciated.  Thanks. Matt

ANSWER: Welding is the way to go, but Only do small stitch welds, you are going way over board with heat. You can cut down how much juice you are putting oput by putting a long extension cord on the welder, also. Be sure the cord isn't wrapped into a coil, and is nicely stretched out onto the concrete floor for safety. Don't try to seam weld, like you are welding together 2 pieces of plate steel. Use half inch long stitch welds, and bounce around. Also, screw, clamp, and rivet the panels into position as close as possible, and cut away excess overlap. You only need a half inch or so overlap.

QUESTION: Great idea on the cord.  I am not exactly sure what you mean by a stitch weld.  How far apart should the half inch welds be? Should I drill holes and plug them?  Thanks again

Answer
Plug welding is an excellent option. Stitch welds are half inch long welds. If you stitch it all the way around, you should eventually completely weld the panel. Bounce around, don't let the heat build up. If the metal is clean, you can just put in 5/16 plug welds every half inch all the way around, then seam seal the panel once you are done with some automotive grade caulk. Bill
