Forging Replacements
Rings, flanges, and structural sections produced net-shape without a die or a queue.

Maritime & Naval
Naval sustainment fails on lead time more often than on capability. B-FSD produces forging replacements without a die, and deposits structural material onto parts already in service, including away from a shipyard.

Primary capability
Bobbin Friction Stir Deposition (B-FSD)
Because B-FSD is solid-state and needs no furnace, no die, and no shielding gas, it travels. That is what makes it viable for repair of parts in service (naval vessels, remote bases, forward operating locations) where the alternative is removing the structure or waiting on a replacement that may no longer be manufactured.
The problem
If Any of These Is True, It Is Worth a Conversation.
01A replacement part is obsolete, sole-sourced, or no longer tooled
02Forging lead time exceeds the maintenance window
03Corrosion or wear damage that currently means replacing a whole structure
04Repairs that must happen at the point of need, not in a shipyard
05Fusion weld repairs introducing distortion, porosity, or cracking
06Dissimilar-metal joints currently carried by bolted or bonded assemblies
Applications
What We Build for Maritime & Naval
02
Repair of Parts in Service
Restoring worn or damaged aluminum structures on vessels and at remote bases.
03
Monolithic Pressure Vessels
Cylindrical structures without a longitudinal seam, removing the joint that drives inspection cost.
04
Feature Addition
Adding bosses, pads, and local thickness to existing structures.
Also for maritime programs
Beyond the Primary Capability
ALSO
Friction Stir Welding
Hull structures, tailored welded blanks, and multi-material joints. Solid-state joints with long fatigue life, minimal distortion, and no filler, and hermetic sealing that gasketed and brazed joints cannot reliably deliver.
Why us
What Stands Behind the Claim
- Solid State, No Melt
- No solidification porosity and no hot cracking, because nothing solidifies from liquid.
- Point-of-Need Capable
- A process that needs no furnace, die, or shielding gas can be deployed where the structure is.
- CMMC Compliant
- Compliant today; ISO in progress. We work to AWS D17.3 or to customer-furnished specifications.
- Federal Contracting
- CAGE 119K1 · UEI U7HMV6HJNF14, across 13 NAICS codes including 336390 and 336414.
Questions
Straight Answers
Do We Need to Buy Any Equipment?
No. You send us a drawing, we manufacture the part, and we send it back. LeapFast does not sell machines.
Can You Deposit Onto a Part Already in Service?
Yes, repair and feature addition onto existing aluminum structure is a core application. Substrate condition and alloy compatibility are assessed as part of the feasibility study.
How Do You Qualify a Repair?
To AWS D17.3 or to the customer specification, with a first-article and test plan agreed before work starts.
Next step
Send Us the Part That Is Holding Up Your Program.
A drawing, a STEP file, or a sketch and a size is enough. We reply within 3 business days, including when the answer is no.
