Capability Overview

OEM Spot Welding Capabilities

Feiyu provides spot welding services for overseas OEM buyers that need stable thin sheet metal joining, repeatable weld points and controlled assembly dimensions. As an OEM spot welding manufacturer, we support custom spot welded parts from drawing review to batch manufacturing.

Our production route can combine sheet metal spot welding, laser cutting, punching, forming, welding, surface finishing and assembly for brackets, clips, cabinets, enclosures and OEM sheet metal assemblies. Feiyu also works as a resistance welding supplier and sheet metal assembly manufacturer China for export-focused projects.

Best Fit

When Spot Welding Is the Right Choice

Review your joint design

Thin Sheet Metal Parts

  • Suitable for overlapping sheet metal joints
  • Stable for repeat OEM production

High-Volume OEM Production

  • Fast welding cycle
  • Consistent weld points
  • Efficient for batch manufacturing

Clean Surface Appearance

  • Suitable for parts where minimal visible weld bead is required
  • Reduces grinding and finishing workload

Low Distortion Assemblies

  • Localized heat input
  • Better for thin metal assemblies than some fusion welding processes

Production Route

Spot Welding Manufacturing Workflow

01

Drawing Review

We review CAD files, weld point callouts, material, thickness, tolerance and surface treatment requirements before production planning.

02

Material Preparation

Material grade, thickness and sheet condition are checked for spot welding compatibility and assembly stability.

03

Laser Cutting / Punching

Sheet metal blanks, holes and features are prepared by laser cutting, punching or related fabrication processes.

04

Bending & Forming

Flat sheet parts are formed into brackets, covers, clips or enclosure components before joining.

05

Fixture Positioning

Fixtures locate overlapping joints so weld points remain repeatable across prototype and batch production.

06

Spot Welding

Welding current, pressure and time are controlled according to material and weld strength requirements.

07

Weld Point Inspection

Weld point position, appearance and consistency are checked before downstream finishing or assembly.

08

Surface Treatment

Parts can be powder coated, zinc plated, painted, brushed or finished according to project requirements.

09

Packaging & Shipment

Finished OEM sheet metal assemblies are protected, packed and prepared for export shipment.

Inspection

Quality Control for Spot Welded Parts

Spot welded parts are controlled through fixture checks, weld parameter monitoring, weld point inspection, dimensional inspection and final packaging review. Learn more about our quality control system.

Process Comparison

Spot Welding vs MIG Welding

Spot WeldingMIG Welding
Best for thin sheet metalBetter for thicker steel parts
Suitable for overlapping jointsSuitable for frames and structural components
Fast cycle timeStrong continuous welds
Clean appearanceCommon for brackets, frames, supports and fabricated assemblies
Low heat inputBetter for thicker welded structures
Common for enclosures, brackets, clips and cabinet partsCommon for structural welded components

Spot welding is often preferred for thin sheet metal assemblies and overlapping joints. MIG welding is usually better for thicker steel brackets, frames and structural welded components.
