Broken welds on door window frame question

[langester]

Hello everyone!
I need to weld up a crack on the front side of my drivers door. The frame cracked just above the weld on the interior side. It is starting to vibrate when I am driving which is not making the crack any smaller. I want to try to save as much paint as possible from getting burnt up, I was going to try cold wet rags. Before I start does anyone have any better solutions?
Thanks in advance!

cold wet makes welded steel brittle. got to get the red out first. If you mig it do a bead cool it and lay the next bead 1/2 into the last one and cool it chicken peck it like it until your done. your still going to burn paint just not as bad. you can also hang a weld magnet in the area to act as a heat sink.

Primary, weld it good first. paint is secondary.

One of the POs of mine welded in a small metal brace over 30 years ago, not pretty but it has held all of these years!

I appreciate the replies. The welding is no problem, I have been doing that for a long time. What I am trying to keep under control is the paint on the outside of the door which is about an inch and a half away from where I am welding. I figured if I can keep that part cool while the actual welded part is still hot it will keep me from having a messed up section of paint on the outside of the door. I plan on using spray paint to fix the inside as best I can. I was just curious if anyone had a better solution.
Thanks again! I always appreciate the help!

That was a good idea. Unfortunately mine is on the front side of the door.

Careful you don't get the glass hot.

I'm assuming you are going to remove the window and felt to weld from the inside? I'd just prep it good with a wire wheel and make the welds quick.

Times 2 on the removing window felt. That stuff catches fire easily. %)

A blow gun nearby to cool the weld helps. You may also want to hold a steel dolly nearby to act as a heat sink. I have used a dolly and a cooling bucket of water to minimize heat distortion when welding sheetmetal.

what about just removing the window frame? that is what i am toying with... just keep the front bit around the triangle-shaped window.

I just repaired the window frame in my drivers door on my 66 this spring. Removed window frame, Wire feed welder, little bead cool skip little bead… sanded with a die grinder and 2” wheel and touch up Paint..
