Hey Guys,
After seeing a little bit of fine welding by others in the forum, I figured I'd show you a pretty neat little machine.

My apologies for such shit pictures, they were taken with my iPhone. But, what you see here is two different paperclips. I'm not a paperclip expert, but one seems to be plated, and one almost seems like it's galvanized. I've no idea, and no real interest anyways, as it was just fun to play. They were shear cut on the end and then I welded them together. One picture shows a little beaded seam weld.

What machine did you use

.


It's gum wrappers at high noon. You will be judged on neatness and penetration of stringer beads and butt welds. All welds WILL be X-Rayed and burning the paper on the back is an automatic disqualification !

Niiiiice!

Laser?

Needs a better manicurist.

Nice job. I had a welding instructor that would TIG razor blades together, edge to edge. He too was an artist in the field.

I did this with a 150J Laser. Settings turned down to about 10% power or so, as this could easily blow all the way thru.

Parent metal fused with no filler I presume

Or powdered metal fusion

No filler. Hold the pieces together, zap, you're done.

That's what I thought looking at them

It is astonishing what can be done with Tig. The butt splice on the paperclip is quite amazing.

I measured the thickness of a paperclip. The ones I have are around .040" in diameter.

We just completed a project welding Super Duplex tubing that was .051 wall thickness and .602" OD. We could not perform autogenous welding, therefore had to use filler metal. The welds were examined with liquid penetrant and then X-Ray was performed with a Selenium tube. Hydrotest pressure is over 10,000 PSI. Prior to production we spent 10s of thousands of dollars on welding procedure testing, performing all Section IX tests plus Ferrite Point Counts, tensiles, yields, etc. etc.
