This came up in conversation with a mate the other day who didnt agree you can weld up trim holes on a swage line and end up with a good finish. "Trim can hide a multitude of sins" he said. Yes it can but I dont want it, here is my solution, hopefully this might help someone else out there.

Take one HQ guard, this one is is a fair bit of a mess, going to take alot of repair work to get it straight again

Holes for trim (plus a few extras). First step is to ensure the swage is straight around where you are going to weld. Mig isnt all that forgiving when it comes to planishing

Much better

This helps alot, take your pick hammer, sit it in the back side of the hole and hit the face end with another hammer. This will flare out the otherside and help prevent any undercutting when you go to run the weld

Like so

Take a strip of copper (or alloy) and hole it on the back side of the hole so you have something to weld against

Weld. I usually do it as a couple of spots and melt the lot together in the final pass. Give yourself plenty of 'crown' on the weld to grind back

Posted Image

Grind back with a flap disc or sanding disc, only go along the swage not across it so you dont create a hollow

Spot the weld?

I go across with a panel file just to get rid of any highs and make sure the line is still there

Happy welding :buttrock:

yeah the copper works a treat hey. i did the same on a radiator support as all the hole didnt line up as it was of another torana, it took a little while but a hell of a lot quicker then trying to plug up the holes with no backing. you gaurd hole repairs came up nice and cant even tell they were there. job well done :buttrock:

So I've heard, want to learn to tig one day but also really want to learn to use the oxy for panel repairs. Copper strip prevents the weld blowing through at the edges makes it easier to form the weld pool. Yes I do, need to set myself up for roloc discs as well and try that out.
