Hi all,
I know there are many differing opinions on Aluminum vs. Steel trailers but I was hoping for some opinions from those that have welded aluminum trailers (versus bolted). As an Engineer who has worked with a fair bit of aluminum I know how soft it becomes in it's annealed state (at the weld joints post welding). I'm assuming these trailers are made out of 6061-T6 which is overall a great choice but how do they retain there strength at the weld joints after welding? I'm assuming the majority of the trailer manufactures aren't retreating the trailers (would need a fairly large oven). Are there any issues with cracking/breaking at the weld joint?
Thanks,
Matt
