How does this compare to the strength of DSFC

Have you considered a induction heating coil? JD Brewer had one in his latest podcast. If all your parts are smallish i would consider that route.

If the customer will go for it offer them a discount to develop the process? Maybe they can send you some test parts to braze/ silver solder. You can send them back for testing and approval.

Tell them your developing a new process to be more efficient, if thier willing to work with you it's mutually beneficial

I'm no CWI, but a series of overlapping spot welds with craters seems problematic. Lack of fusion, stess cracks all seem highly probable. But hey it's just a role cage, what could go wrong...........

Yes the bottom of the weld would be 4F I believe. I cleaned everything back to bright clean material.

Thank you

Hey guys, I need some Dual Sheild help.
Dual Sheild Flux Core, Lincoln ultra core .045 71T
-22v @ 240in/min 75/25 @ 45cfh- 3/16 square tube
-25v @ 250 in/min 75/25 @ 45 cfh- 1/4- 5/16" D ring tabs

If I have a problem with the weld falling out, large balls of weld, would that generally indicate running too cold? Not enough arc force. I tend to weld alot of D Rings. The top weld goes in perfect, the bottom 4f t joint I always have problems.

I appreciate any advice

Kevin Fox thanks, I pulled off some decent welds.

I can't seem to get overhead figured out. It wants to fall out bad. Maybe hotter with more arc force?

That's more then I have seen without a contaminated tungsten.

Post flow, bad gas, air leak, contaminated tungsten

Any tips to diagnose worm hole porosity? I seem to always get it.
