Re: Wood vs. Metal racks

I’ve done everything from TIG to submerged (not to be confused with underwater) and thermoplastic. For piddling around the house, making simple projects and doing some minor structural work, the SMAW is IMHO the most cost effective and better all around. And if you are good with a torch, you can make clean cuts, and it is not only cheaper, but takes up less room when your shop consists of a 12 foot by 12 foot shed.
But to each their own. We all have our preferences. 
dude we are building racks not skyscrapers and its not 8020 its 8018 either way (cliped from lincoln's site)SuperArc® LA-90 is our premium copper coated, low alloy MIG wire manufactured to meet tensile strength requirements of 80,000 to 90,000 psi (552-620 MPa) minimum. The addition of 0.5% molybdenum provides strength after stress relief. Ideal selection when welding ASTM A182, A217, A234 and A335 high temperature pipe, fittings, flanges and valves and A336 pressure vessel forgings. Best mechanical properties are achieved with an 98-95% argon, 2-5% oxygen shielding gas blend.
they also have higher strength than that.
i said mig not fcaw
and id like to see cuts in 16 gauge or less with a torch without major warpage!
around the house most ppl would weld usually thin metals typically under 1/4 inch.
on another note ive been welding for along time and ive been certified since 96 with gmaw tig smaw pulsearc fcaw by both the AAR and AWS. im a union ironworker used to be a union boilermaker and i have a degree in Metallurgy and used to build railroad pressure vessels.
