Try Bohler Welding GroupFOX NICUCR for MMA.
Union Painax for MIG . Think they do flux cored wire.
Elga have cheaper alternatives
There is a lot of rumors\problems with CT embritlement of welds, rusting big time etc.
Read some where buildings getting demolished due to rust problems

I used to make wood stoves out of CorTen and used plain old rods and wire. But your answer is in Graham's link. The thickness is not too much, so that the weld pool will have enough of the dilution from the parent metal to gain the anti rust advantages.

Most of the ones I've seen are mild steel. There's a firm here that makes them and their stock looks like ordinary mild. If they were Corten why would they paint them ?

Aren't the corten rods designed to have the limited rusting and then blend into the parent metal for colour?

Found this from Archinsteel mag.If interested rest of write up

Using weathering steel in construction presents several challenges. Ensuring that weld-points weather at the same rate as the other materials may require special welding techniques or material. Weathering steel is not rustproof in itself. If water is allowed to accumulate in pockets, those areas will experience higher corrosion rates, so provision for drainage must be made. Weathering steel is sensitive to humid subtropical climates. In such environments, it is possible that the protective patina may not stabilize but instead continue to corrode. For example, the former Omni Coliseum, built in 1972 in Atlanta, never stopped rusting, and eventually large holes appeared in the structure. This was a major factor in the decision to demolish it just 25 years after construction. The same thing can happen in environments laden with sea salt. Hawaii's Aloha Stadium, built in 1975, is one example of this. Weathering steel's normal surface weathering can also lead to rust stains on nearby surfaces.
The U.S. Steel Tower in Pittsburgh, Pennsylvania was constructed by U.S. Steel in part to showcase COR-TEN steel. The initial weathering of the material resulted in a discoloration of the surrounding city sidewalks, as well as other nearby buildings. A cleanup effort was orchestrated by the corporation once weathering was complete to clean the markings. A few of the nearby sidewalks were left uncleaned, and remain a rust color. This problem has been reduced in newer formulations of weathering steel. Staining can be prevented if the structure can be designed so that water does not drain from the steel onto concrete where stains would be visible.

Both will corrode over time in a salty environment ie at sea.. Thats why they are painted inside and out. Yes the Corten will stand up to weather a bit longer than plain old mild steel, but when salt comes into the equation I cant see it making much difference personally

If you're not putting it back on the road then I can't see that the ultimate strength of the welds will matter all that much. As far as resistance to corrosion is concerned then there's little to beat building up layers of paint - primer, undercoat and top coat. For areas that aren't seen a good layer or two of underseal would do the job.
If it wasn't for the costs involved I would have bought an old container instead of the steel sectional garage I'm erecting as my new workshop. Even with all the mods I've made to it, it's coming in at around £500. Not bad considering it's going to be 3 metres wide X 7.5 metres long with 2 metre+ walls, has half the roof panelled in clear plastic, secure front and side doors and will have a full 40 amp (single phase only) mains consumer unit.

Obviously it's second hand, but there isn't a speck of rust anywhere on it. That is NOT an exaggeration! Although the seller even supplied a a pair of sliding front doors and a used uPVC door for the side I'll only be using the plastic one. I'll be fitting much stronger hardwood doors to the front in a single and 2-fold configuration for better security. As it was an all steel construction (since beefed up with a tonne or more of pre made roof trusses) I'm replacing half the roof panels with clear corrugated plastic to permit daylight into it. When you step in through the side door you can't even tell you're indoors! I'll post a couple of pics when it's finished.
Yes, I'm in the progress of adding some thin insulation to all the walls, but not the roof of course. In the short run I'll be heating it with a small Calor gas heater, but only until the 47Kilo propane cylinder runs out. Then I'll be cutting it up and turning it into a rocket wood burner. However I may have a source for some stainless beer barrels that would do a better job in that regard. I'll have to nip over and see if they're still there.
