MIG welding isn’t hard. Not really. Especially with all the new automatic welders that allow you to set your material thickness and forget it. Like anything it is all about practice. And luckily getting in some good practice with a MIG welder is pretty easy. Setup isn’t hard, you can weld any two pieces of scrap together, and with enough time you can be putting down beads that are clean and functional. Here’s the catch.
Welding flat plates together, or angle iron, or even tubing, isn’t hard when it is all at 90 degree angles. And on a bench. But when you start talking about 30, 45, and 60 degree angles, which are very common when building roll bars and roll cages, then things get trickier. Especially when said joints are inside a car that you have to get yourself into. In order to become an expert at the angles, so that the variable of welding inside the car becomes less of a hindrance, getting tips and trick and practice in on joints like this is key to making nice passes inside the vehicle.
This is where having someone with experience give you the tips and tricks can really make a difference. Thankfully Miller is all over it, and in this video they have Chris Jarman from Eliminator Kustoms giving some very good advice on how to weld these particular joints. It’s the little things, like where to start and stop the weld, that can make the difference between a roll bar or cage that will pass inspection and save your life, vs one that won’t do either.
In addition, this video also discusses welding techniques and welder settings based on these joints. Lots of good info in just a few minutes.
Watch and learn.
