We also appreciate the open communication between our companies which has allowed us to meet critical program objectives.

The RS-68 Team would like to thank Weldmac for a job well done, and look forward to a long-lasting relationship.”


Supplier Recognition Award: LOCKHEED MARTIN

“During late 2001 and early 2002, Weldmac Manufacturing Company went above and beyond the call of duty by developing a new process for manufacturing the F-22 Engine Inlet K-Seal Titanium Inserts. Not only is the process they developed 70% faster than the prior process, it is also easier, cost effective and more accurate. While this in itself is commendable, this award nomination is for the expedited effort that solved a significant schedule problem. Weldmac went out on risk to manufacture the tools before the official drawings were available, worked long hours and weekends, utilized all of their in-house talent, and pulled favors from local manufacturers and businesses to support the F-22 programs schedule as much as possible.

Weldmac’s achievement is important because the difficulty in manufacturing the inserts had caused a serious shortage in deliveries of the Inlet K-Seal. The K-Seal is the last part incorporated before the engines can be installed during final assembly. With the K-Seal six months late to the 4011 need date and no relief in sight for follow-on aircraft, Weldmac in five short months recovered the schedule for subsequent aircraft and is now in sequence for 4016.

Overall the company has demonstrated the will and the ability to do whatever needs to be done to provide quality hardware on time. We believe that Weldmac deserving of recognition as an outstanding team player.
