high spot help
I recently welded in a headlight trim ring to French them in.. Now that I'm blocking out the body work I'm finding little high spots in a few areas. These are right next to or in close proximity to a the weld (MIG weld. <- that's all I have) How do I go about lowering these down without cracking the MIG weld? Torch? Shrinking disc? Any help/advice is greatly appreciated.
Thanks TJ

Hi,
A picture would help, but it sounds like a job for a shrinking disk. Remember, if you shrink to much, you can always stretch back to shape. Bill

I'd have to ask, 'high spots next to or close to the weld' may not be highspots but the result of the areas adjacent are shrunk.
In any event, a shrinking disc would make things easier.

high spots
Anytime you weld (mig,tig,oxy) you are gonna get shrinkage.You should have hammer& dollied out this shrinkage at the HAZ area.

Every time I tried to hammer the haz it would crack around the welds

A doughnut dolly and a slapper might do you some good. Depends on how soft the metal is.

The problem with using a shrinking disc or a torch to shrink that is the heat is going to break the bond between the plastic filler and the panel which means you have to re-do a good portion of your plastic work. Looking at how small that spot is I’d think you should be able to tap it down with a hammer that has a small hit point unless there is a reinforcement under it. An alternative to a hammer is an automatic center punch with the tip blunted out……… my friend Lazy Danny swears by the method. The best idea of all is to lightly file all your metal work to find highs before using filler to avoid these type of problems before they even start. ~ John Buchtenkirch
