shipping container

[johnik]

me again
ive been asked to weld some tabs on a shipping container,they are to take some hefty pad locks,i believe the containers are made from a special steel?
i have the choice of arc or mig,any advice?

thanks for that,now to find some rods

i dont think its too dificult to weld as normal steel
will just rust different

i would certinaly try conventional methods first

thanks for that,now to find some rods

Last time i welded Cor ten, i used E8018s. Can't remember if it was anything to do with the structural properties, or to get a colour match with the parent metal/welds when it rusted.

Last time i did any it was just plain ol wire for what it was.

I think the rods have a bit of nickelin them from memory....
TechnicAL will have the answer to this one im sure....

According to this forum wot we're on, it's 7018 for under 10mm, or A18 mig wire; and 8018 (I assume, but don't take my word for it) for over 10mm or multi-pass. UKW also says 8018.

So for containers it's 7018 ir A18.

It's for the weathering properties.

You learn something every day.
I've welded loads and never realised it was different

if its not going to sea & only for storage or whatever, does it really matter?
