 If it's stainless you need to get the welds passivated to eliminate free iron in the welds. It won't affect the integrity but aesthetically doesn't look great.

 As andy said, its a simple process (if you havent refitted it already)

Just a matter of brushing on a pickling paste (Nitric acid?) and washing off after 20 min.

But it wont get off the rust your seeing, only stops it forming. So you need to get that clean.

Do NOT use a normal wire brush, or even a SS wire brush thats ever touched mild steel as it will do the same thing.

Dont get pickling paste on your boat!

 As above, and find out what filler rod was used on the weld. Sounds like the welder may not be familiar with SS welding.
