Custom Metal Welding Manufacturing Service

Manufacturing Insight: Custom Metal Welding

Precision Metal Welding Integrated Within Honyo’s Comprehensive Sheet Metal Fabrication Solution

At Honyo Prototype, custom metal welding is not an isolated process but a critical, seamlessly integrated capability within our end-to-end sheet metal fabrication ecosystem. We engineer precision-welded assemblies for demanding industrial, aerospace, and medical applications where structural integrity, dimensional accuracy, and material compatibility are non-negotiable. Our certified welders deploy TIG, MIG, and laser welding techniques across stainless steel, aluminum, titanium, and specialty alloys, ensuring metallurgical soundness and adherence to AWS D1.1/D1.3 and ISO 9001 standards. This integration eliminates supply chain fragmentation, reducing lead times by up to 30% compared to outsourcing welding separately.

Honyo’s sheet metal fabrication services encompass every stage from initial design analysis through forming, CNC punching, bending, finishing, and final assembly. Our in-house capabilities include laser cutting tolerances of ±0.1mm, precision press braking for complex geometries, and rigorous in-process inspection using CMM and vision systems. Material traceability and weld procedure specifications (WPS) are documented for full compliance, providing clients with auditable quality control from raw material to finished component. This holistic approach ensures welded joints meet exact mechanical and aesthetic requirements without secondary handling delays.

Technical Capabilities

Custom metal welding services at Honyo Prototype integrate precision laser cutting, CNC bending, and advanced welding techniques to deliver high-integrity fabricated components. These processes are optimized for a range of materials including aluminum, steel, and compatible thermoplastics such as ABS and nylon—though welding methods differ significantly between metals and plastics.

While metals like aluminum and steel are joined using laser, MIG, or TIG welding, thermoplastics such as ABS and nylon are typically fused using hot gas, ultrasonic, or solvent welding methods. Laser cutting and CNC bending are primarily applicable to sheet metals and are not used with thermoplastic sheets in the same manner as metal.

Below is a detailed technical specification table outlining process capabilities and material compatibility:

Process	Laser Cutting	CNC Bending	Welding Techniques
Material Compatibility	Aluminum, Steel	Aluminum, Steel	Aluminum, Steel, ABS, Nylon
Thickness Range	0.5 mm – 25 mm (Al), 0.5 mm – 20 mm (Steel)	0.8 mm – 12 mm (Al), 0.5 mm – 15 mm (Steel)	0.8 mm – 10 mm (Al/Steel), up to 6 mm (ABS/Nylon)
Tolerance	±0.1 mm	±0.2° angular, ±0.1 mm linear	±0.5 mm fit-up, ±1° alignment
Tooling	Fiber laser (up to 4 kW)	CNC press brakes with 100–300 ton force	Laser welders, TIG/MIG systems, plastic welders
Surface Finish	Smooth, oxide-free edge (Al), minimal dross (Steel)	Clean bend lines, no tool marks	Smooth weld beads, post-grind optional
Joint Types	Not applicable	Not applicable	Butt, T-joint, lap, corner (metal); scarf, lap (plastic)
Notes	No kerf on plastics; plastics require CO2 laser or alternative	Not suitable for ABS/Nylon	ABS/Nylon: hot gas or ultrasonic welding only

All fabricated components undergo in-process inspection and final quality verification to ensure dimensional accuracy and structural integrity. Honyo Prototype supports full DFM feedback and rapid prototyping for complex welded assemblies across industrial, automotive, and consumer applications.

From CAD to Part: The Process

Honyo Prototype Custom Metal Welding Process Overview
Honyo Prototype delivers precision custom metal welding services through a streamlined, technology-driven workflow designed for engineering accuracy and manufacturing efficiency. Our process eliminates traditional quoting delays and integrates proactive design validation to ensure weld integrity and cost-effectiveness from initial concept to final shipment.

CAD File Upload and Initial Processing
Clients initiate the process by uploading native or neutral CAD files (STEP, IGES, Parasolid, SolidWorks) via our secure customer portal. The system performs immediate format validation and geometric integrity checks. Proprietary file formats are converted to neutral standards without feature loss, and any topology errors are flagged for client review before proceeding. This stage typically completes within 15 minutes of submission.

AI-Assisted Quoting with Engineering Oversight
Uploaded geometry is analyzed by our proprietary AI engine trained on 12+ years of welding production data. The system identifies material types, joint geometries, tolerances, and weld access requirements to generate a preliminary cost model. Crucially, this is not a fully automated quote; a Senior Welding Engineer validates the AI output within 2 business hours, adjusting for factors like residual stress implications, fixturing complexity, or specialized certifications (e.g., AWS D1.1, ASME IX). Clients receive a formal quotation with material traceability documentation and weld procedure specifications (WPS) within 24 business hours.

Design for Manufacturability (DFM) Weld-Specific Analysis
Upon quote acceptance, our DFM team conducts a rigorous weld-focused review. This phase identifies potential fabrication risks and optimizes joint design for structural performance and production efficiency. Key elements analyzed include:

Feedback Category	Specific Checks	Resolution Path
Joint Geometry	Root gap consistency, bevel angle feasibility	Recommend GTAW root pass for tight gaps
Material Compatibility	Dissimilar metal weldability, HAZ sensitization	Propose nickel-based filler for 304-6061 join
Distortion Risk	Asymmetrical weld sequencing, restraint adequacy	Add temporary stiffeners in CAM programming
Accessibility	Torch clearance, in-position weld feasibility	Suggest fixture rotation or alternate joint

Clients receive a detailed DFM report with annotated CAD visuals and engineering rationale. 92% of projects require 1-2 revision cycles, typically resolved within 48 hours.

Production Execution and Quality Control
Approved designs move to production in our climate-controlled welding bay. All welders hold active AWS certifications, and procedures are pre-qualified per client specifications. Key production stages include:
Precision CNC cutting of base materials using fiber laser systems with ±0.1mm tolerance. Fixturing via modular jigs designed from DFM recommendations to minimize distortion. Weld execution with real-time monitoring of amperage, voltage, and travel speed. Post-weld heat treatment applied per material requirements when specified. Comprehensive NDT including 100% visual inspection, dye penetrant testing for critical joints, and X-ray on aerospace/medical components. Final dimensional verification against original CAD via CMM or laser tracker.

Delivery and Documentation
Completed assemblies undergo final cleaning and protective coating if specified. Each shipment includes:
Material test reports (MTRs) with full chemical and mechanical properties
Weld procedure qualification records (PQRs) and welder certification documentation
As-built dimensional inspection report with deviation analysis
Packaging engineered for shock and moisture protection during transit
Standard lead time from DFM sign-off to delivery is 7-12 business days for low-complexity assemblies, with expedited options available.

This integrated process reduces welding rework by 68% compared to industry averages and ensures first-article compliance with stringent industry standards. The combination of AI-driven initial analysis and deep engineering oversight in DFM and production delivers predictable quality while accelerating time-to-prototype for complex metal fabrications.
