In precision sheet metal fabrication, a single poor weld can compromise a whole product. From industrial enclosures to machine parts, durability isn’t negotiable — and that’s exactly where advanced welding services make the difference.
At Nhat Nam Sheet Metal, we don’t just “join” sheet metal. We engineer every weld to last through time, vibration, and use, especially in industries where failure isn’t an option.
When Standard Welding Just Isn’t Enough
In conventional workshops, welding sheet metal (especially thin stainless or aluminum) often leads to:
Distorted surfaces
Uneven penetration
Cracks during stress or polishing
Misalignments during assembly
For clients in pharma, food, and high-precision industries, these issues are unacceptable.
That’s why we developed our own in-house approach to sheet metal welding:
Pre-jig alignment for consistent tolerances
Pulse MIG and TIG for thin gauge control
Weld sequencing to eliminate heat warping
Seamless weld blending for hygienic and cosmetic surfaces
What Makes Our Welding “Advanced”?
We combine technical setup, operator skill, and quality control in one flow.
Pre-Welding Setup
Each job is pre-fixtured with laser-cut locating tabs or dowels to ensure zero movement during weld. This improves repeatability even for large batches.
TIG + MIG Hybrid Approach
We don’t stick to just one method. Instead, we combine MIG’s speed with TIG’s precision — choosing what works per joint, per material, per job.
Stainless Hygiene Welding
For pharma/food-grade projects, we meet requirements like:
Minimal crevices
Full weld penetration
Mirror-polish blending
We understand that in these applications, a clean weld = product safety.
Testing and Inspection That Go Beyond “Visual OK”
We inspect beyond just eye-checks:
Dye-penetrant tests for crack detection
Load or pressure testing (on request)
In-weld control using amperage tracking
Need full documentation for overseas customers or OEM compliance? We’ve handled it.
Designed for Scale – From 1 Part to 10,000
We handle everything from:
One-off prototypes with complex welding geometry
Medium batch assemblies requiring welding + bending + powder coating
High-volume production with fixture-based repeat welding
Our welding zone is integrated within our full fabrication line (laser cutting → bending → welding → finishing), meaning you don’t waste time between processes.
Where Do These Welded Parts Go?
Our parts are already in use across:
Stainless steel enclosures for cleanrooms
Machine frames shipped to Japan & Korea
Welded hoppers and trays for food factories
Custom brackets for automation systems
Whether your part is exposed, load-bearing, or hygienic, we weld it to fit real-world stress.
Work With Us
Most clients come to us after a bad supplier experience — warping, cracks, or just poor finish.
At Nhat Nam, we offer:
Welded samples for first article inspection (FAI)
Joint recommendations based on CAD or sketch
Material + weld compatibility consultation
Full-fabrication quotes — not just welding
