Four Welding Processes, One Supplier

The right process depends on material, thickness and what the joint has to survive. Our engineers pick it for you — free, with every quote.

HIGH VOLUME

MIG Welding

  • Best for: 1–20 mm carbon & stainless
  • Fast deposition, clean welds, low splatter

HIGH PRECISION

TIG Welding

  • Best for: 0.5–8 mm stainless & aluminum
  • Distortion-free, cosmetic-grade bead
  • Medical, food-grade, visible joints
  • Where the weld must look as good as it holds
MICRO JOINTS

Laser Welding

  • Best for: 0.3–3 mm thin gauge
  • Minimal heat-affected zone, no warping
  • Electronics, enclosures, sealed housings
  • Little to no post-weld finishing needed
HEAVY DUTY

Arc Welding

  • Best for: 6–20 mm thick plate
  • Deep penetration, high strength joints
  • Machine bases, heavy frames, structures
  • Cost-effective on thick structural steel

Weld Quality Verification

A weld that looks fine can still fail. Here is how we prove it will not — testing scope agreed with you before production.

Visual Inspection (VT)

100% of welds. Checks bead profile, undercut, porosity, spatter and dimensional conformity against drawing.

Dye Penetrant (PT)

Surface crack detection on critical joints. Standard for pressure-bearing and safety-critical parts.

Ultrasonic Testing (UT)

Internal defect detection in thick-section welds without cutting the part. Available on request.

X-Ray / Radiographic (RT)

Full internal weld imaging for high-stress structural and pressure applications. Arranged via certified partner.

Leak Testing

Pressure or immersion testing for sealed enclosures, tanks and housings that must hold fluid or gas.

Dimensional Report

Post-weld measurement against your drawing, accounting for shrinkage and distortion. Issued with every shipment.

Third-party welcome: SGS, BV and TUV inspection can be arranged at any production stage. We also accept your own nominated inspector on site.

Volume Pricing Guide

Indicative FOB Tianjin ranges for welded fabrication. Welding cost is driven by weld length, joint access and fixture complexity — not part count alone.

Assembly Type Typical Spec 10 pcs 100 pcs 1,000 pcs Volume Saving
Simple Weldment 2–4 parts, carbon steel 2–4 mm, MIG $12–30 $6–16 $4–11 up to −65%
Stainless Enclosure SS304 1.5–2 mm, TIG + polish $45–110 $25–60 $16–40 up to −64%
Machine Frame Q235 6–12 mm, arc weld + powder coat $90–260 $55–160 $38–110 up to −58%
Aluminum Assembly AL6061 2–5 mm, TIG + anodize $35–95 $20–52 $13–35 up to −63%
Riveted Panel Assembly SPCC 1–2 mm, riveting + hardware insert $8–22 $4–12 $2.5–8 up to −68%

Note: Ranges are indicative and for budgetary reference only. Welded assemblies vary widely — final pricing depends on weld length, number of components, fixture requirement, NDT scope and finish. Custom fixtures, when needed, are quoted separately. Request a firm quote for binding pricing.

How It Works

Send Assembly Drawing

2D/3D files showing joints and weld symbols. No weld callouts? We will specify them for you.

Process & DFM Review

We recommend MIG, TIG, laser or arc based on your material, thickness and joint access — free with the quote.

Fixture Design

Custom jigs built in-house to control distortion. This is what separates a flat assembly from a warped one.

Weld & Inspect

Certified welders, agreed NDT scope, post-weld dimensional check against your drawing.

Finish & Ship

Grinding, coating, plating and assembly. Export packaging engineered for freight.

Why Buyers Choose DEEPLINK for Welding

🔨Cut, Form & Weld In-House

Laser cutting, bending, stamping and welding under one roof. No coordinating three vendors, no finger-pointing when parts do not fit.

📏Fixtures Built In-House

Distortion is the number one welding failure. We design and build the jigs ourselves rather than welding freehand and hoping.

🔬NDT to Your Spec

VT, PT, UT, RT and leak testing available. You define the scope; we document every result and ship the report.

📝Free Weld DFM

We flag inaccessible joints, over-specified weld sizes and callouts that add cost without adding strength.

⚖Factory-Direct Pricing

No trading company markup. You talk to the engineer who assigns the welder to your job.

🔒IP Protection

NDA signed before you share drawings. Your assemblies are never reused or shown as portfolio samples.

Frequently Asked Questions

Which welding process should I choose?

It depends on material, thickness and what the joint must do. TIG for thin stainless and aluminum where appearance matters; MIG for carbon steel production volume; laser for thin-gauge electronics housings; arc for thick structural plate. Send your drawing and we recommend the process free of charge with your quote — you do not need to specify it yourself.

How do you prevent warping on welded assemblies?

Three ways: custom fixtures built in-house to hold alignment during welding, controlled weld sequence to balance heat input, and stress relief where geometry demands it. Post-weld dimensional inspection confirms the assembly is within tolerance before it ships.

Do you provide weld inspection reports?

Yes. Visual inspection is standard on 100% of welds, with a dimensional report issued for every shipment. Dye penetrant, ultrasonic, X-ray and leak testing are available — agree the scope with us upfront and results are documented in your file.

Are your welders certified?

Yes. Our welders are qualified for the processes and materials they run, working under ISO 9001:2015 documented procedures. If your project requires a specific qualification standard, tell us at enquiry stage and we will confirm compliance before quoting.

Can you weld dissimilar metals?

In many cases yes — stainless to carbon steel is routine with correct filler selection. Aluminum to steel requires transition joints or mechanical fastening. Send your requirement and our engineers will confirm feasibility rather than guess.

What is the minimum order quantity?

One piece. We build single prototype weldments and production batches on the same equipment, so your prototype reflects the real production process.

Do you handle the parts before welding too?

Yes — that is the main reason customers come to us. Laser cutting, bending, stamping, machining and welding all happen in-house. One supplier owns the whole assembly, so there is nobody to blame when parts do not fit.

What are your payment and shipping terms?

Samples: 100% before production. Volume orders: 30% deposit, 70% before shipment. L/C accepted above USD 50,000. We ship EXW, FOB, FCA, CIF, DAP and DDP worldwide via sea, air and express courier.
