Stainless Steel Welding Services
Zibo Cook offers professional stainless steel welding services for commercial kitchen equipment and custom fabrication projects. Our certified welders perform TIG and MIG welding on 201, 304, and 316 stainless steel, delivering sanitary-grade welds for food contact surfaces and structural welds for heavy-duty equipment.
Welding Capabilities
Automatic welding station used for repeat welded assemblies.
- TIG Welding – Precision welding for thin-gauge stainless steel, sanitary tubing, and visible joints requiring cosmetic finish
- MIG Welding – High-productivity welding for thicker materials and structural components
- Automatic Welding Line – Robotic welding for consistent repeatability on batch production
Quality Standards
Weld dressed to a food-safe finish.
- Food-grade sanitary welds with no crevices or bacteria traps
- Full penetration welds for structural integrity
- Passivated and pickled finish for corrosion resistance
- Visual and dimensional inspection on every weld
Applications
Frame assembly tacked square before final welding.
Custom sink fabrication, work table assembly, exhaust hood ductwork, food processing equipment, and stainless steel structural frames.

Frequently Asked Questions
What is the difference between TIG and MIG welding?
TIG welding provides higher precision and cleaner welds, ideal for food-grade sanitary applications. MIG welding is faster and better suited for thicker materials and structural components.
Do you provide on-site welding services?
We primarily perform welding in our factory. For large projects requiring on-site installation, please contact us to discuss arrangements.
Can you weld 316 stainless steel?
Yes. We weld 304, 201, and 316 regularly, with filler selection and post-weld treatment matched to the grade – see our 316 fabrication page.
How do you ensure weld quality?
Every seam is visually inspected, and liquid-bearing products such as sinks and bain-maries are leak-tested before packing. Material mill test certificates are available on request.
What is the MOQ and lead time for welded assemblies?
One unit, with standard production in 3-5 working days. Samples are ready in 3 days, and large-volume orders add about 5 days – see our custom order and lead time page.
Can you weld from customer drawings?
Yes. Our OEM manufacturing service covers welded assemblies built to your drawings, branding, and tolerances.
Do you ship finished weldments internationally?
Yes – worldwide shipping with DDP door-to-door to the US and EU. Our packaging and shipping page covers how finished fabrications are packed.

Our Welding Expertise
Zibo Cook employs certified welders with extensive experience in stainless steel fabrication. Our team is skilled in both TIG and MIG welding processes, allowing us to select the most appropriate method for each application. TIG welding is our primary method for visible joints and sanitary applications, as it produces clean, precise welds with excellent control over heat input and penetration.
For heavier structural components and longer weld seams, MIG welding offers higher deposition rates and faster production speeds. Our welders are trained to work with various stainless steel grades and thicknesses, ensuring proper fusion and minimal distortion regardless of the project requirements.
Quality Assurance in Welding
Weld quality is critical for both the appearance and performance of stainless steel equipment. We follow established welding procedures for each material grade and thickness combination. Visual inspection is performed on every weld to check for proper penetration, consistent bead appearance, and absence of defects such as porosity or undercut.
For food contact surfaces, we ensure that welds are smooth and free of crevices where bacteria could accumulate. This sanitary weld finish is achieved through careful technique and post-weld grinding and polishing when required. Our quality standards meet the requirements of commercial kitchen equipment and food processing applications.
Custom Welding Projects
Beyond standard fabrication, we take on custom welding projects that require specialized approaches. Whether you need custom brackets, frames, enclosures, or structural supports, our welding team can deliver. We work from your drawings or samples to produce welded assemblies that meet your exact specifications.
