Welding processes

Industrial Welding Processes for Custom Metal Products

We select welding methods based on material, structure, thickness, appearance requirements, and product use.

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

We weld different metals based on product use, strength requirements, surface finish, and assembly needs. Material selection can be reviewed according to your drawings or samples.

DFM tip: weld gaps, bead size, access direction and fixture datum should be confirmed before bulk welding.

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.

Surface finishes

Surface Finishes for Welded Products

After welding, Yishang can coordinate grinding, deburring and finishing so products arrive closer to final use.

Finish

Grinding

Smooths weld areas and sharp edges before finishing or assembly.

Finish

Polishing

Improves appearance for stainless steel and visible metal surfaces.

Finish

Brushing

Creates a clean directional finish for stainless steel products.

Finish

Powder Coating

Provides color, protection, and durable surface coverage for welded metal products.

Finish

Painting

Suitable for industrial frames, cabinets, racks, and structural welded parts.

Finish

Zinc Plating

Adds basic corrosion protection for small steel components and hardware-related parts.

Finish

Anodizing

Used for aluminum parts where appearance and corrosion resistance are required.

Finish

Passivation

Helps improve corrosion resistance for stainless steel welded products.

Quality assurance

Welding Quality Checks Before Shipment

For welded products, small problems can lead to poor assembly, weak structure, surface defects, or installation delays. Before shipment, we check weld appearance, key dimensions, assembly fit, surface condition, quantity, labeling, and packaging to help reduce after-sales issues.

QC

Weld Appearance

Checks for visible defects, rough welds, burn marks, and areas needing grinding or finishing.

QC

Dimensional Check

Key dimensions, hole positions, and assembly-related features are checked against drawings.

QC

Assembly Fit

Important connection points and installation areas are reviewed before packing.

QC

Packing Review

Finished welded products are packed according to size, surface finish, and export handling needs.
