GE Aviation has demonstrated capability for a Cold Metal Transfer (CMT) repair – a new, low-heat metal build-up (additive technology) process for repairing seals on rotating parts that restores the seals to original dimensions.
Specifically, its low-heat input reduces crack sensitivity during the repair process – improving repair cycle time by 2.5X (vs. more conventional methods) and significantly improving yield, which translates to saving/repairing the part rather than having to purchase a completely new one.
Equipment has recently been installed in GE Aviation’s repair facility in Cincinnati, and the repair is expected to be offered to customers soon. For more information on CMT, contact Lorna Hyman.

“We first developed the process for GE90-94B hardware,” says Scott Fentress, GE Aviation’s Component Repair GM, “and its application is being expanded to other materials and engine components from various engine lines.”
