Edit: Can't find it on the page, but does mention GMAW welding in the testimonials....http://www.sigmalabsinc.com/index.php?page=testimonials
Applied to welding, Sigma's IPQA is fully closed loop and is what they originally did before applying it to Additive Manufacturing which is basically welding, but with lasers. That's why they re-applied for the closed loop control patent specifically for AM-- but it got rejected because the USPTO said that it overlapped/ was already covered by their existing patent that stated welding. I believe they mentioned additive processes in their current patent-- but they wanted it in the title or something so there would be absolutely no mistaking their IP. I'm pretty sure it was the welding IPQA that they sold to....Boeing? or one of those people they were working with in 2011/12.
