Welding Services
Custom welding services for OEM metal products, welded assemblies, frames, enclosures, brackets, chassis and housings. From prototype samples to bulk production, Yishang helps buyers reduce weld defects, deformation, rework and supplier coordination risk.
What We Weld with Our Custom Welding Services
Built for OEM buyers who need stable weld quality across samples, pilot runs and repeat batch production.
Sheet Metal Enclosures
Welded boxes, panels, covers and cabinet structures for industrial equipment.
Equipment Frames
Fixture-welded frames, bases and support structures for repeat production.
Structural Assemblies
Multi-piece welded assemblies with controlled fit-up and welding sequence.
Metal Brackets
Welded brackets, mounts and supports with dimensional inspection.
Chassis & Housings
OEM chassis, housings, trays and welded product bodies.
Why Choose Yishang's Welding Services
Welding is where many OEM projects lose control: inconsistent bead quality, heat distortion, poor fixture planning, delayed finishing and parts that fail assembly after shipment. Yishang focuses on welding feasibility review, fixture control, sample approval and repeatable batch production.
You get one coordinated supplier for welding, finishing, assembly checks, packing and export communication.

Industrial Welding Processes for Custom Manufacturing
Choose a welding service based on material, thickness, strength requirements, cosmetic expectations and production quantity.
MIG Welding
Efficient welding for carbon steel, stainless steel and aluminum products where speed and stable strength matter.
TIG Welding
Clean weld appearance and better heat control for stainless steel, aluminum and visible welded products.
Spot Welding
Fast resistance welding for overlapping sheet metal, covers, brackets and light-gauge assemblies.
Arc Welding
Flexible welding option for thicker structures, frames and project-specific welded assemblies.
Materials for Welding Services
Material selection affects weld strength, heat input, deformation, corrosion resistance and finishing cost. Send your drawing and required material so we can review weldability before quoting.
Stainless Steel
Good for corrosion-resistant enclosures, covers and visible products.
Carbon Steel
Cost-effective for frames, brackets, bases and structural assemblies.
Aluminum
Lightweight welded products where heat control and surface protection matter.
DFM tip: weld gaps, bead size, access direction and fixture datum should be confirmed before bulk welding.
Welding Tolerances
Welding tolerances depend on product size, material, heat input, fixture control and post-weld finishing. Final requirements should be confirmed against your drawing.
Prototype samples, pilot runs and repeat OEM production
Drawing-specific target, commonly confirmed before production
Per drawing requirement or sample approval
Approx. 0.5 – 10.0 mm depending on material and process
Fixture support, sequence planning and local correction when needed
Visual weld check, dimensional inspection and surface review
Surface Finishes for Welded Products
After welding, Yishang can coordinate grinding, deburring and finishing so products arrive closer to final use.
As Welded
Fast economic state for hidden or internal welded areas.
Grinding
Weld bead smoothing for safer handling and cleaner appearance.
Brushing
Directional texture for visible stainless steel or aluminum surfaces.
Polishing
Improved cosmetic appearance for selected visible products.
Bead Blasting
Uniform matte surface before final finishing.
Powder Coating
Durable coating for cabinets, frames and industrial products.
Painting
Color finish for OEM housings and welded assemblies.
Passivation
Corrosion resistance support for stainless steel products.
Anodizing
Surface finish option for suitable aluminum welded products.
Electroplating
Functional or decorative metal coating when project requires.
Silk Screening
Printed logos, labels or instructions after finishing.
Heat Treatment
Project-specific mechanical property support.
Quality Assurance for Welding Services
Welded products can fail from poor fit-up, distortion, missing welds, weak seams or finish damage. Yishang builds checks around the points that matter for OEM buyers: drawing review, fixture planning, first-piece confirmation, weld appearance, dimensions and packing.
For repeat orders, we keep key process notes so the next batch can be produced more consistently.
Weld Appearance
Visual checks for bead continuity, obvious defects and surface condition.
Dimensional Check
Critical dimensions checked after welding and before finishing.
Fixture Review
Support for repeatable fit-up and distortion control.
Packing Review
Surface protection and export packing before shipment.
Welding Services FAQs
MIG welding is efficient for production and thicker structures. TIG welding offers cleaner appearance and better heat control for visible or precision-sensitive welded products.
Yes. Yishang can coordinate metal fabrication, welding, finishing, assembly checks and packing for OEM metal products.
We support MIG welding, TIG welding, spot welding, arc welding and project-specific welded assembly work depending on drawings, material and quantity.
Yes. Samples or pilot runs can be arranged so bend, fit-up, weld appearance, dimensions and finishing can be confirmed before bulk production.
