NADCAP Approvals
Offering NADCAP approved welding services and currently holding 24 month merit status.
Lynn Welding provides NADCAP Approved GTAW Welding & NADCAP Brazing services.
Lynn Welding provides NADCAP approved welding services for most aerospace primes. Lynn Welding has 16 NADCAP approved welders and 18 Nadcap approved resistance spot welding machines. We have an excellent reputation throughout the aerospace community, and we are known as the most responsive and transparent aerospace welding company. Lynn Welding has certified welding inspectors (CWI’s) on staff which is now becoming a requirement from various aerospace primes.
Lynn Welding also has department managers for each welding service that we provide. You can contact our fusion, resistance and brazing managers anytime for immediate technical assistance or status of your order.
In 2018 Lynn Welding processed over 160,000 parts for our various customers with minimal quality and delivery issues. In the rare case that a delivery or quality issue should arise, our department managers are trained to notify the customer well before the actual due date so that an appropriate recovery plan can be implemented.
Lynn Welding is currently on Merritt status with NADCAP brazing. This means that our processes are very robust, and we have less than 2 minor findings during our typical 4-day audits. Merrit status allows us to extend our audit cycle which in turn reduces costs to Lynn Welding and our customers.
