> thin metal weld question

I've got a little DIY/hobby project on the go. Part of the job requires fixing a stainless steel washer or small plate to a ss tube. The washer needs to be attached to one end of a short length of the tube (about 5cm) and allows the tube to then be fixed at right angles to a piece of wood. I'll have a go at posting a picture if all that's not very clear.

Now, the wall thickness of the ss tube is only 0.5mm. Is this a job that could be done with a weld?

You will need to TIG it....or find someone that can

Thanks, Al
I'd suspected that the cheaper and simpler options might not be available.
D'y think silver brazing might give me a servicable joint? There's no huge physical stress involve here.

Yes but you will need a special flux which I believe is expensive and very aggressive / nasty.

Thank again.
Just been looking at the flux. Bit pricey but managable. The 'nasty' bit is more of a problem.
The project application calls for food-grade user safety and that might be hard to guarantee with the
flux's chemical components. I'll look into it a bit further but atm it's looking like a friendy TIG
welder's gonna be my best bet.

Happy New year,
