- Materials: carbon steel, stainless steel, aluminum; thickness from 1 mm to 25 mm.
- WPS/PQR documented; welders qualified to AWS/ISO standards for repeatable quality.
Technical Advantages
Process Engineering
DFM for weldment design, distortion control, and fixture development—optimized bead path, heat input, and cycle time for stable quality.
Precision & Automation
Robotic welding with seam tracking and pulse control; CNC post-machining ensures datums and holes meet tight tolerances.
Finishing & Traceability
Bead grinding, shot blasting, powder coating, and zinc plating available; full lot traceability and material certificates supplied.
Quality Control
Comprehensive Quality Assurance
Welds verified by visual inspection, macro etch, and NDT (UT/MT/PT) where required; dimensional checks performed on CMM with full reports.
High-Performance Custom Welded Parts for All Industries
Turnkey welded assemblies engineered for strength, flatness, and repeatability—trusted in machinery, construction, transportation, and energy applications.
Welded Brackets & Frames
MIG/TIG welded brackets and rigid frames built on precision fixtures for stable geometry and load-bearing performance.
Structural Weldments
Heavy-duty bases and columns with controlled distortion, verified by NDT when required for safety-critical use.
Sheet-Metal Welded Assemblies
Enclosures, guards, and housings with TIG seams, deburring, and cosmetic finishing for visible surfaces.
Stainless Steel Weldments
Clean TIG welding with passivation and brushing; ideal for food, medical, and corrosive environments.
Aluminum Welded Assemblies
Lightweight frames and fixtures with controlled heat input to preserve strength and dimensional stability.
Custom Welded Fabrications
Built-to-print assemblies with machining, tapping, and finishing—powder coat, zinc plating, or e-coat available.
Prime Custom Metal Welding Process
From fixture design to final coating, our welding workflow delivers strong, dimensionally stable assemblies with full traceability and repeatable quality—ready for your production lines.
1. Requirements & Weldability Review
Align CTQs, loads, materials, and standards (AWS D1.1 / ISO 3834). DFM recommendations cover joint design, access, and tolerance stack-up to minimize cost and risk.
2. Process Plan & Quotation
Provide WPS/PQR route, heat input targets, sequence, and cycle times. You receive a detailed quotation including timeline, inspection plan, and documentation package.
3. Fixture Design & Tooling
Engineer modular jigs with 3-2-1 locating to control flatness and parallelism. Fixtures accelerate changeovers and stabilize dimensions for both robotic and manual cells.
4. Material Prep & Edge Conditioning
Source certified steels, stainless, or aluminum. Laser/plasma cut, machine, and bevel; clean edges and set root gaps to spec for consistent penetration.
5. Fit-Up & Tack
Components are clamped in fixtures to control gaps and squareness. Tack welds lock geometry and reduce cumulative distortion prior to final welding.
6. Welding Execution (Robotic & Manual)
MIG/MAG, TIG, spot, or stud welding executed to WPS parameters with monitored voltage, current, wire feed, and travel speed for repeatable bead quality.
7. Distortion & Metallurgy Control
Apply optimized sequence, back-stepping, pulse modes, and interpass temperature control. Stress-relief or normalizing is added where required by spec.
8. NDT & Dimensional Inspection
Visual inspection plus MT/PT/UT as specified. Datums, holes, and flatness verified on CMM; full reports (FAI/PPAP/COC) available.
9. CNC Post-Machining & Hardware
Machine critical faces and bores; drill and tap to tolerance. Install PEMs/studs or bushings where specified to finalize the assembly.
10. Surface Finishing & Corrosion Protection
Bead grinding, shot blasting, powder coat, e-coat, zinc plating, or passivation. Coating thickness and cosmetics verified to spec.
11. Packaging, Logistics & Support
VCI bags, foam, and reinforced crates with barcode labels and full traceability. Terms EXW/FOB/CIF/DDP; ongoing engineering support and fixture maintenance included.
