How many are talking about?

Which end of the U pin is to be attached?

What are the loads to be imposed on the joint?

What are the materials?
 
Thanks uclesyd,
new product now hundreds could climb to thousands,
both ends of U pin are attached to support plate, i.e U pin forms bracket,
joint loading is 2 to 4 pounds
materials 304 stainless steel, application temp 250C (482F)
 
Your temperature and plate thickness precludes essentially everything except welding or brazing (furnace) with preforms.

From the back side:
I think that MIG Spot Welding is the best approach for the small numbers. The plate thickness of 5 mm may necessitate two small through plate holes, essentially a plug weld. The holes and weld would be small due to the load requirements. This would be an autogenous weld.

This could possibly be accomplished in a normal spot welder with a little set up.

From the front side:
I have also seen this accomplished with a stud welder(arc) with a special head.

MIG Spot Welding

How much distortion can you have in the plate?

Does the plate have any other holes in it?
