Custom Fabrication and Welding
Laser cutting, CNC bending and stamping through TIG, MIG, laser and resistance welding. Weldments, enclosures and structural parts from one supplier.
What Is Custom Fabrication?
Custom fabrication is cutting, forming and joining metal stock into finished parts, with no casting or moulding. Meco runs seven of those processes in house: laser cutting, CNC bending, stamping, TIG, MIG, laser and resistance welding.
Most parts use several at once. An enclosure is cut, bent, spot welded, then hardware installed and coated. That full route is covered on our sheet metal assemblies page. Pair it with CNC machining and surface finishing and the part ships finished.
Why Buyers Choose Meco
Splitting a fabricated part across a cutter, a welder and a coater is where cost and fit problems start. Here is what changes when one shop owns the build.

Which Process Fits Your Part?
Volume, tooling and tolerance decide the cheapest route. Send a drawing and we will price two options side by side.
| Process | Best Volume | Tooling | Thickness | Tolerance |
|---|---|---|---|---|
| Laser Cutting | 1 to 100k | None | 0.5 to 25 mm | 0.1 mm |
| CNC Bending | 1 to 100k | Low | 0.5 to 10 mm | 0.5 deg |
| Metal Stamping | 10k to 1M+ | High | 0.3 to 6 mm | 0.05 mm |
| TIG Welding | 1 to 10k | None | 0.8 to 10 mm | 0.5 mm |
| MIG Welding | 1 to 50k | None | 1.5 to 25 mm | 1 mm |
| Laser Welding | 1k to 500k | Fixture | 0.3 to 6 mm | 0.2 mm |
| Resistance Welding | 10k to 1M+ | Fixture | 0.3 to 6 mm | 0.3 mm |
Building a formed and joined enclosure rather than a single part? Start with sheet metal assemblies for stack-up and gap guidance.

First Article Inspection
Full dimensional report before production is released.
Weld Inspection & NDT
Visual, dye penetrant, ultrasonic and X-ray on critical joints.
Material Certs
Mill test reports and EN 10204 3.1 certs on request.
CMM Verification
Critical features and hole patterns checked against your GD&T.
Questions People Ask
What does custom fabrication cost?
Roughly $3 to $15 for a cut and bent bracket, $0.30 to $5 for a stamped part, and $40 to $500 or more for a weldment. Drivers are broken down in our pricing guide.
What is the lead time?
Laser cut prototypes in 5 to 10 days, welded prototypes in 2 to 3 weeks. Stamping tooling takes 4 to 10 weeks, then 1 to 2 weeks per batch.
Which welding processes do you offer?
TIG, MIG, laser and resistance welding, all qualified to AWS D1.1 with NDT available.
What tolerances can you hold?
0.1 mm on laser cut features, 0.5 degrees on bend angle, 0.05 mm on stamped parts, and about 0.5 mm across a welded assembly. ISO 2768-mK applies unless your drawing says otherwise.
Is there a minimum order?
No MOQ on cutting, bending or welding. Stamping needs 5,000 to 10,000 parts to justify hard tooling, though soft-tool samples of 100 to 500 are possible.
Do you build complete assemblies?
Yes. We weld, install hardware, finish and assemble complete units. See sheet metal assemblies or mechanical assembly.
Can you weld aluminum and stainless?
Yes. TIG covers aluminum 3003, 5052 and 6061 and stainless 304 and 316, with correct purging for cosmetic thin-gauge seams.
