Yeah with a stick welder E7018 works real good,or for tig use 309L stainless filler wire. Personally,I would pre-heat it before welding and when your done let it cool down very slowly.

Buy an electric hotplate!

I use my oven but then again I'm a single guy!

I was referring to use the hot plate as a method I use to pre and post heat when welding..stick the housing on the hotplate....

Yes. I would think the hotplate would allow the part to coll rather quickly as opposed to having the part in an oven where it would be brought back down to room room temp much more slowly. I'll give the hot plate a try in the future. Havent been welding as much as Id like to lately
