Re: Is this Weldable ???
My experience comes from 30 years as a Certified Welder from high pressure boiler tube to HDPE pipe. I have certified at 6G and all other positions and sizes, with bend test and x-rays. We have welded a little bit of everything in my industry and career.
MIG is a lot easier and much more prevalent for the home mechanic. TIG (which requires HF) is a much more expensive machine and generally not in most peoples garages. With a MIG you can run a across the top, down the side and back across the bottom. With a TIG, you are going to have an issue when you go upside down and weld it in an overhead position. I can do it, but no way would I when I can MIG it.
I like to TIG (and is required) for a root-pass on HP boiler pipe. In the old days it was with a 6010 and then we welded out with a 7018. I use to weld up aluminum props with a stick so I have done it a lot of ways, but for what you have there, a good quality MIG weld will serve you well. I have never ever had an issue with it from repairing frames, to extending DS's, to adding on brackets or braces on many many CC golf cats.
