Projection Welding

Projection Welding

Projection Welding

I need to have 6 bushings welded to a plate and projection welding appears to be the most cost effective solution.  My problem is I cannot find bushings that are commercially available, and I'm not exactly sure how to design the bushing for this process.  Can anyone suggest a vendor or advise on the design for the bushings

RE: Projection Welding

Projection welding (similar to spot welding) works well with materials usually no thicker than 1/8".

What is the function of your bushings and their size?  Can you use a self-clinching bushing that is pressed into your plate?

RE: Projection Welding

Unfortunately no.  The plate is really a standard sprocket for a stamping supplier and the quantities that are required are too low to invest in new tooling.  The spacers are going to be used as offsets for the sprocket.  I don't want to get into tacking all the spacers on the sprocket and a full weld is overkill.  I thought that projection welding would be a good solution.  Thanks for the input.

RE: Projection Welding

Try posting in forum725 for other users to comment since your question is more geared towards projection welding.  But make sure you provide a link back to this topic too.

Can you design a one-piece spacer instead of 3 separate bushings?
