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.

Custom welding applications

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

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.

Welding processes

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

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.

Weldable metals

Stainless Steel

Good for corrosion-resistant enclosures, covers and visible products.

Weldable metals

Carbon Steel

Cost-effective for frames, brackets, bases and structural assemblies.

Weldable metals

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.

Tolerances

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.

Capability

Prototype samples, pilot runs and repeat OEM production

General Fabrication Tolerance

Drawing-specific target, commonly confirmed before production

Weld Size

Per drawing requirement or sample approval

Welding Thickness

Approx. 0.5 – 10.0 mm depending on material and process

Distortion Control

Fixture support, sequence planning and local correction when needed

Inspection Methods

Visual weld check, dimensional inspection and surface review

Quality assurance

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.

QC

Weld Appearance

Visual checks for bead continuity, obvious defects and surface condition.

QC

Dimensional Check

Critical dimensions checked after welding and before finishing.

QC

Fixture Review

Support for repeatable fit-up and distortion control.

QC

Packing Review

Surface protection and export packing before shipment.

FAQ

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.
