Sigma Labs Receives Contract From Alcoa For Advanced Manufacturing Process Development

August 3，Sigma Labs, Inc. announced  that it received a contract from Alcoa, Inc. (NYSE: AA) to demonstrate the feasibility of applying Sigma Labs' In-Process Quality Assurance (IPQA) technology to the welding of advanced aluminum structures.  Sigma Labs expects this exploratory contract to generate up to $36,859 in revenues.

Vivek Dave, Executive Vice President of Sigma Labs, states, "Alcoa demands very high quality control requirements for materials joining.  As such, they require advanced quality assurance technology like IPQA to make acceptable parts initially, and continuously, thereby avoiding costly inspection of joints.  Sigma Labs was engaged by Alcoa because of our world-wide expertise in process monitoring." Mark Cola, President of Sigma Labs, states: "The IPQA preliminary trials with Alcoa showed that the technology performed remarkably well.  The trials found subtle defects intentionally introduced into welds.  Based on these results, Alcoa is considering further evaluation of IPQA's capabilities with other welding processes."
