Custom Sheet Metal Welding Services
Get precision joining for your sheet metal assemblies, from single prototypes to 100,000+ monthly units, our IATF 16949 certified welding integrated with your fabrication for complete, ready-to-use components.
What is Sheet Metal Welding
Welding permanently joins metal components through controlled heat and pressure, creating bonds as strong as the base material itself. As a critical step in our sheet metal fabrication process, welding transforms your laser-cut and CNC-bent parts into complete, production-ready assemblies.
Common Welding Applications in Sheet Metal Fabrication
- Structural Joining
- Enclosure & Housing Assembly
- Component Attachment
- Sub-Assembly Creation
- Cosmetic & Visible Joints
- Functional Requirements
The Right Weld for Every Application
Not every joint needs the same approach. We match the optimal welding method to your part’s requirements—balancing strength, appearance, speed, and cost.
When you need thousands of consistent joints per day without consumables eating into your margins, spot welding delivers. Each weld takes under a second, and our 18 stations mean your order won't wait in queue.
No filler material—eliminates wire/gas costs on high-volume runs
Sub-second cycle—keeps your unit cost low at scale
Minimal heat zone—no warping on thin panels
18 dedicated stations—capacity when you need it
HVAC condenser frames, automotive brackets, appliance housings, or any assembly requiring dozens of joints per part at production volumes.
When your weld will be visible to end customers—or your geometry demands precision a human hand can't sustain across 10,000 parts—our FANUC robotic cells deliver ±0.1mm repeatability, batch after batch.
±0.1mm accuracy—cosmetic welds that don't need grinding
Minimal distortion—thin materials stay flat
Complex 3D paths—reaches angles manual welders can't
Batch consistency—part 10,000 matches part 1
Automotive sunroof frames, visible consumer product seams, intricate bracket geometries, or any application where inconsistency means rejects.
When your assembly needs to bear serious loads—equipment frames, structural supports, heavy-gauge enclosures—MIG welding deposits strong, deep-penetrating joints that won't fail under stress.
Deep penetration—structural joints that hold under load
High deposition rate—faster on thick materials
Versatile materials—carbon and stainless steel
Cost-effective—economical for larger weld beads
Equipment frames, machine guards, structural brackets, industrial enclosures, or any assembly where joint strength matters more than aesthetics.
When the weld IS the product—architectural metalwork, premium appliances, visible stainless joints—our certified TIG welders create smooth, clean beads that require zero post-processing. Also your go-to for aluminum.
Show-quality finish—welds you're proud to display
No spatter—clean surrounding surfaces
Aluminum capable—your lightweight material option
Prototype friendly—perfect for development runs
Architectural metalwork, food equipment (sanitary welds), aluminum enclosures, prototype development, or any application where the weld must look as good as it performs.

Frequently Asked Questions
What types of welding does ZAKFAB offer?
We offer spot welding (resistance), robotic laser welding, MIG welding, and TIG welding. Our primary capability is high-volume spot welding with 18 dedicated stations, complemented by FANUC robotic laser welding for precision applications.
What's the minimum order quantity for welded assemblies?
We support everything from prototype quantities (1-10 pieces) to production volumes (100,000+ per month). Our flexible capacity allows us to scale with your project needs.
Can you weld my laser-cut parts from another supplier?
While we can accommodate this, the best results come from our integrated process where we control cutting, bending, and welding tolerances together. This eliminates fit-up issues and ensures consistent quality.
Do you provide weld samples before production?
Yes, we provide first-article samples with full dimensional reports. If specified, we can also include destructive test results showing weld cross-sections and pull-test data.
What certifications cover your welding process?
Our welding operations are covered under IATF 16949:2016 and ISO 9001:2015 quality management systems. All welders are certified per applicable standards.
Can you weld aluminum?
Yes, we have TIG welding capability for aluminum up to 2mm thickness. For aluminum applications, we recommend discussing your specific requirements with our engineering team.
