whats the difference? im trying to buy some mandrel bends on jegs and the aluminized looks cheaper. why is that. still weldable the same way? ---

WELDING IT IS MORE OF A PITA BUT IT DOES RUST MORE SLOWLY. BUT STILL RUSTS. ---

[quote=“boardjnky4,post:3,topic:27582"”] gotcha, but does it weld with standard mild steel wire? [/quote] yes, but it tends to burn through if you are trying to weld pipe to pipe, be very carfule with teh edges, your going to have to stich the welds, if you overheat teh edges they will cave in and ull spend the next 20 minutes trying to fill the weld… its annoying, i bought them accidently on jegs and tried to pie cut them for a complex bend in a DP and gave up after all teh uglyness ---

Welding aluminized gives off some really nasty fumes. Even when you clean it well. It will mess with you. ---

[quote=“Carnut,post:8,topic:27582"”] Welding aluminized gives off some really nasty fumes. Even when you clean it well. It will mess with you. [/quote] Yeah, the zinc coating BLOWZZZZ, even if cleaned, there still will be residual zinc inbended into the base metal. Turns into nasty gas (phosgene? i believe). But in anycase, it is the suck. Weld quality will suffer as well (welds tend to be pourous, and brittle). ---

Personally I have never had a problem with welding aluminized pipe with the MIG welder. If you are picky you can clean it off with a brown roloc and then wipe it with acetone. I guess it would depend on what you are looking to build. Just a cheap custom exhaust get the aluminized. If you want something nice get the mild steel, weld it up then ship it to JetHot to be coated
