AMK has a well-earned reputation for welding complex assemblies. Our plant encompasses 40,000 square feet in South Windsor, CT.

Our range of services includes electronic beam (EB) welding, GTAW welding, GTAW semi-automatic welding, robotic, 7-axis GTAW welding, and vacuum heat treatment. Our large inert chambers create a controlled environmental for the welding of specialty metals, and they are supplied by a central manifold system.
We are certified to AS9100C and ISO 9001: 2008. Acquired by Air Industries Group in October of 2014, AMK is fortified for growth. We have the resources available to finance major projects, and to capitalize as required to support new programs.
