I have a child bicycle seat made so that a child can ride in a bike behind an adult. This seat has two legs made of steel, that are not long enough to properly fasten to bicycle frame neat the rear axle hub.
I would like to extend this piece and can use 304 stainless. Can I safely weld 304 to mild steel, with E308 filler rod?
The dealer told me to use 312 for mild & stainless. This is the job:

I found a way to do what I wanted, without welding. It would be a lot better in many respects. But thanks, I will remember it.

To weld stainless to carbon steel you can use basic 308L filler, but the welds may crack over time.
312, and 309 are better choices for dissimilar metals.
I have had good luck with 310 for general welding of 'difficult' steels. There was a time when it was quite common to use 310 ss for welding tip shanks on heavy digging buckets as it gave good life under high impact loading.
Good luck, YMMV
