Sheet Metal Welding Services
TIG, MIG & Spot Welding for Production-Ready Assemblies
Rapidaccu provides professional sheet metal welding services for prototypes through mass production. We combine laser cutting + CNC bending + welding + finishing under one roof in Shenzhen to deliver strong, clean, and consistent weldments — supported by an ISO 9001 quality system and fast logistics.
Sheet Metal Assemblies Built for Real Products
From simple brackets to complex multi-part housings, we weld sheet metal assemblies that must pass fit, function, and appearance requirements.
Equipment Housings & Covers
Protective covers and housings for industrial and commercial equipment applications.
Chassis, Frames & Brackets
Structural welded assemblies for load-bearing and support applications.
Electrical Boxes & Cabinets
Control boxes and cabinets requiring precise fit and reliable sealing.
Battery Boxes & New Energy
Enclosures for battery packs and charging equipment in new energy applications.
Server & Communication Housings
Chassis and housings for server racks and communication infrastructure.
Panels, Mounts & Sub-Assemblies
Fixtures, mounting hardware, and welded sub-assemblies for diverse applications.
TIG / MIG / Spot Welding
We select the process based on material, thickness, joint design, cosmetic requirements, and throughput.
TIG Welding (GTAW)
Gas Tungsten Arc Welding
Best for fine control, clean beads, cosmetic surfaces, thin materials, and stainless steel/aluminum applications where appearance matters.
MIG Welding (GMAW)
Gas Metal Arc Welding
Efficient for production, strong joints, and repeatable weld quality on steel/stainless where speed and throughput matter.
Spot Welding
Resistance Spot Welding
Ideal for sheet-to-sheet lap joints, brackets, cabinet structures, and fast, consistent joining without continuous beads.
Have a drawing with welding symbols? Send it — we’ll match the required method and acceptance criteria.
Send Your DrawingMaterials We Weld
We support common sheet metals used in industrial manufacturing. If you have material grade, temper, and surface condition requirements, include them in the RFQ.
What “Good Welding” Means in Production
Professional customers don’t just want a weld that “holds” — they need predictable, inspectable results. We engineer for:
Correct Weld Spec
Correct weld size, location, and continuity per drawing specifications and callouts.
Stable Fit-Up
Controlled gaps and stable fit-up before welding to ensure joint integrity.
Distortion Control
Protect flatness and assembly alignment through controlled heat input and sequencing.
Clean Bead Profile
Especially important for cosmetic faces and surfaces requiring finishing treatment.
Smooth Transitions
For finishing compatibility — powder coat, paint, plating, and other treatments.
Dimensional Control & Distortion Management
Thin sheet metal can warp if heat input and sequence aren’t controlled. If your assembly has flatness, perpendicularity, or critical hole position requirements, mark them clearly as CTQ dimensions.
Proper Fixturing
Clamping strategies to hold parts in position during welding
Tack Strategy
Welding sequence planning for optimal stress distribution
Heat Input Control
Process parameters and travel speed management
Joint Design Review
Fit-up review during drawing evaluation phase
Post-Weld Correction
Straightening solutions when required and approved
Welding + Sheet Metal Fabrication — One Supplier, One Timeline
Welding quality depends on upstream processes. Rapidaccu supports the full workflow. This integration reduces miscommunication, shortens lead time, and improves final assembly fit.

Surface Treatment & Final QC
Complete finishing and quality verification before shipment
Post-Weld Surface Finishing
We provide post-weld finishing options to meet cosmetic and performance specs. For stainless assemblies, specify whether heat tint control/cleanup is required for appearance and corrosion performance.
ISO 9001 Quality System & Pre-Shipment Inspection
Our welding service is managed under an ISO 9001 quality system with full-process monitoring and final verification. If you require inspection reports, define the format and CTQ features in your RFQ.
Quality Controls Include:
Optional Weld Inspection Methods
Depending on product requirements, we can support common inspection approaches. Tell us your acceptance standard or internal requirements so we can align the inspection plan.
Visual Testing
For bead profile, discontinuities, and workmanship evaluation.
Liquid Penetrant Testing
For surface-breaking indications (material dependent).
Magnetic Particle Testing
For ferromagnetic materials (steel) — detecting subsurface indications.
Leak Testing
For sealed enclosures — define method and acceptance criteria.
