The "best" process is subjective, but most professional welders can weld almost anything almost anywhere with almost any process. That said, the ones I work with clearly prefer TIG over MIG, and MIG over stick, and stick over torches. I suggest you find someone to teach you whose equipment you can also borrow, and follow their guidance - there are enough ...


Tig welding should be fine as long as your machine is designed for welding at that thickness. For example if your frame rails are formed from 1/4" thick steel, you should be using something like a 300 amp tig setup.


You have a couple of options: Open butt joint Butt joint with backing Lap Joint Offset joint Open Butt Joint Source I would not recommend this for joining frame rails, even though some manufactures (Toyota for example) recommend this type joint for sectioning procedures. Butt joint with a backing Can be made from a piece of one of the frame rails, ...


I was watching the show called Stacey David's Gearz ... it's one of those Saturday morning vehicle shows (at least that's the time I see it). He's been around the block a couple of times and his shows are a little cheezy, but he seems very knowledgeable. This one episode I saw, he was shortening the frame of a C10 to take it from a long bed to a short bed ...


TIG (Tungsten Inert Gas) is used generally on thinner metals and or aluminum. It would have less penetration than MIG (Metal Inert Gas) Welding. I would not recommend TIG welding the Frame on any vehicle.


I would recommend checking the regulations of an appropriate race series, as anything that meets or exceeds these specifications should also be suitable for road use. For example, the UK MSA regulations on Roll-over protection state: K1.3.8. Guidance on Welding. All welding should be of the highest possible quality with full penetration and preferably ...


Fish plating a frame is typically used when someone is building a custom frame and two pieces of steel are met and a plate is created to overlap both pieces to add structure support:


You could run a tap through the bolt after powder coating You could add a step to your process. After everything is complete. Nut welded to frame Complete Powder coating Run a tap through the nut to clear out any powder coating in the threads so you have good metal to metal contact with your grounding bolt. The tap should not have any negative effect ...


If there is no metal to metal contact, there is no ground. That applies to both of your scenarios. The powder-coating will act as an insulator. Personally, I would drill the hole in the frame, install a bolt through the hole. Powder-coat that so that there is a bare spot under the head of the bolt that doesn't get covered. Then use that bolt to install ...
