It's not easy to summarize metal fabrication/welding in a few words. We might be able to be more specific if we knew your level of experience. However, the following points may help get started: Match your weld metal to the material being used. Regular mild steel (60k psi) in normally welded with common weld metals that have a 70K psi strength. TIG welding is great for many uses, but usually requires more experience and is generally considered a slower weld process compared to stick or MIG. MIG welding equipment is readily available and easily operated by beginners with minimal practice. I recommend using a shielding gas, rather than using 'flux-cored wires'. And several alloy wires are available to match your material & meet your strength requirments. Hope this helps develop more specific questions, LL

I agree 100%. The best thing to do with this project is to look for books on metal frabrication, welding, and meterial selection to better equip yourself for the task. There are far too many skills and methods used in fabrication and welding to even do a hint of justice on this fourm. The best advice I can give is to plan it several times and do it once. You can experment on small pieces before you weld. BUT, if you weld it with no experience with depth of weld, heat selection, and electrode selection you may find your project falling apart at the most dangerous moments. I recommend you use a welder (person that welds). The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

We have had the best experiences TIG welding using mar-aging rod (XX.977.T). This rod joins metals without becoming brittle. It is very forgiving of conditions not being ideal as well.
