Fiber Laser Welding Services
MJM Manufacturing operates nine IPG fiber laser welders — one of the largest fiber laser welding capacities in the Southeast — producing clean, low-distortion, high-strength welds for aerospace, defense, and precision sheet metal assemblies. Backed by AWS D17.1 (Lockheed Martin approved) and Lloyd’s Register certification.
Overview
Why Fiber Laser Welding
Fiber laser welding uses a tightly focused, high-intensity laser beam to fuse metal with a very small, precisely controlled heat-affected zone. Compared to conventional TIG and MIG welding, that concentrated energy means far less heat input, minimal distortion, and narrow, cosmetically clean weld seams — which is exactly what demanding aerospace, defense, and precision-enclosure work requires. It’s fast, repeatable, and ideal for thin-gauge materials that would warp or burn through under traditional processes.
With nine IPG fiber laser welding systems in-house, MJM has the capacity to run prototypes and production volumes without the bottleneck most shops hit with one or two stations. Every weld is performed under our AS9100 quality system and supported by qualified Weld Procedure Specifications (WPS) and Procedure Qualification Records (PQR).
Advantages
The Benefits for Your Parts
Low, concentrated heat input means thin and precision parts stay flat and dimensionally stable — critical for assemblies with tight tolerances.
Narrow, uniform seams need little to no post-weld finishing — ideal for visible, cosmetic, or Class-A surfaces.
Deep, consistent penetration produces strong, repeatable joints that meet aerospace and defense structural requirements.
Faster travel speeds and consistent parameters make it efficient for both prototypes and production runs.
Welds thin materials that would burn through or warp under conventional TIG/MIG — without sacrificing joint quality.
Nine IPG systems mean no single-station bottleneck — we scale from one prototype to full production.
Applications
What We Weld
Aerospace & defense components: Structural and non-structural assemblies, brackets, housings, and precision hardware welded to AWS D17.1 — the aerospace fusion welding standard MJM holds under Lockheed Martin program approval. Ideal for programs demanding low distortion, full traceability, and certified documentation.
Sheet metal enclosures & assemblies: Cabinets, chassis, boxes, and frames where clean, cosmetic seams and flatness matter — electronics enclosures, control panels, and equipment housings.
Precision & thin-gauge parts: Components where heat distortion would ruin fit or function — thin stainless and aluminum assemblies, medical and instrumentation hardware, and tight-tolerance weldments.
Materials: Stainless steel, aluminum, carbon steel, and other weldable alloys. Not sure if your material or joint is a fit? Send your drawings and our team will advise on the best process.
Certified Quality
Welding Credentials
MJM’s welding program is backed by credentials that matter for aerospace and defense work: AWS D17.1 aerospace fusion welding with Lockheed Martin program approval, plus AWS D1.1 (structural steel), D1.2 (structural aluminum), and D9.1M (sheet metal). Our welding procedures and welder qualifications also carry Lloyd’s Register third-party certification (LR 33932). Every process is supported by qualified WPS and PQR documentation and performed under our AS9100 quality system, with full material traceability and first article inspection available.

FAQ
Fiber Laser Welding FAQ
What is fiber laser welding?
Fiber laser welding uses a focused, high-intensity laser beam delivered through a fiber-optic system to fuse metal with a very small, precisely controlled heat-affected zone. It produces narrow, clean, high-strength welds with minimal distortion — making it ideal for thin-gauge, precision, and cosmetic applications where TIG or MIG would introduce too much heat.
How is fiber laser welding better than TIG or MIG?
The concentrated laser energy puts far less heat into the part, so there is much less warping and distortion, a narrower and more cosmetic weld seam, faster travel speeds, and the ability to weld thin materials that would burn through under conventional processes. For thin, precision, or visible welds, fiber laser welding usually produces a better result with less post-processing.
What materials can MJM fiber laser weld?
MJM fiber laser welds stainless steel, aluminum, carbon steel, and other weldable alloys, in both thin-gauge and heavier assemblies. If you are unsure whether your material or joint design is a good fit, send your drawings and our engineering team will advise on the optimal process.
Is MJM’s welding certified for aerospace and defense?
Yes. MJM holds AWS D17.1 aerospace fusion welding qualification with Lockheed Martin program approval, along with AWS D1.1, D1.2, and D9.1M, and Lloyd’s Register certification (LR 33932). All welding is performed under an AS9100 quality system with qualified WPS/PQR documentation, material traceability, and first article inspection available.
