Good thread. I felt the need to chime in. 1) I am a certified welder and certified welding inspector. As with so many things in life, there is more than one "Right" way to accomplish a given task. People will tend to stay in their comfort zone, and that is fine. Each of the processes discussed above have advantages and disadvantages. What I will say is that on a very tangible level, I have tested and certified many welders over the past ten years, and one thing I can say with absolute certainty is that if you are going to be welding these chassis, if you have not had your eyes checked in a few years, do so. Probably 75% of the welders that fail a welding cert. test, do so because they cannot frankly see what they are doing properly. 2) I know this is a "locost" forum, and that welding equipment is a major investment for a hobby. I strongly encourage people to buy a name brand piece of equipment from a local distributor. Support and parts are much easier to deal with, and many distributors will even help you set up the machine for the intended purpose. That is invaluable for those that have never welded before. While the internet is a great source of information, as we all know there is also a LOT of misinformation. With respect to GMAW, or Mig, I also recommend that you clean all pieces before welding, and make a few test pieces to cut apart to make sure you are getting good penetration. Since these projects will most likely all be in short circuit mode, it is very easy to have a good looking fillet weld, and have absolutely zero penetration on one side or the other of the joint if it is not clean
