Patching unused bolt holes in Aluminum

[Randy V]

Thx for the concern. I will practice on some scrap 3/16 plate with 1/2” plugs and will use a series of tack welds so plenty of time for cooling.

Cooling wasn’t really one of my issues, other than trying to contain warpage. My Miller Dynasty 200DX AC TIG and air-cooled torch would not generate the heat needed for proper aluminum welds on my RCR. I had to add supplemental heat with MAP gas torch.

Randy, Thx much. Given the heat sink mass of the chassis, preheating to 200F makes sense. These welds are only going to be tack welds and the patch is not structural so all I need is a little penetration to hold the plug and allow for grinding the tacks flush with chassis. I am going to get a professional to add mounts and bungs to the fuel tanks. I am not taking any chances with crucial welds. Cheers, Randy.

Everything you need to know right here. I learned how to TIG with an Eastwood unit in order to build the front spoiler on my 69 Firebird. Sold that a few years ago and decided to buy a Prime Tig unit from Jodie's site at xmas time. I'll use it to do my bundle of snakes.
