Product DescriptionSpecificationDiscriptionOur professional welding services cover a full range of industry-standard processes, including Shielded Metal Arc Welding (SMAW)—also known as stick welding—using flux-coated electrodes for unmatched versatility in on-site fabrication, repair, and outdoor jobs. We utilize Gas Metal Arc Welding (GMAW/MIG welding), which feeds a continuous solid wire electrode with inert or active shielding gas (e.g., argon, CO2), delivering high efficiency for thin to medium-gauge materials and ensuring clean, spatter-free welds. For thick-section fabrication, our Submerged Arc Welding (SAW) process—where the arc is submerged in granular flux—enables high deposition rates, deep penetration, and minimal fume, making it ideal for heavy-duty structural work. Additionally, Flux-Cored Arc Welding (FCAW) is a go-to for outdoor or windy conditions, as its tubular flux-cored wire eliminates the need for external shielding gas while providing strong, corrosion-resistant welds.Welded steel structures fabricated through these precision processes are engineered for strength, durability, and reliability, serving critical roles across industries:In construction, they form the backbone of skyscrapers, bridges, stadiums, and industrial warehouses, leveraging high load-bearing capacity and weld integrity to withstand extreme forces.In manufacturing, welded frames, crane booms, and machinery bases rely on our high-deposition welding techniques to ensure rigidity and longevity in heavy operations.Automotive and shipbuilding sectors trust our MIG-welded and SMAW-welded components for chassis, hulls, and structural supports, where weld seam strength and dimensional accuracy are non-negotiable.Renewable energy projects, such as wind turbine towers and solar panel supports, depend on our welded structures for their balance of structural resilience, cost-effectiveness, and resistance to environmental stress.Whether you need stick welding for on-site repairs, MIG welding for precision fabrication, or SAW for heavy steel sections, our welding solutions deliver consistent quality and performance for your most demanding projects.ManufacturerZhejiang Puxing Precision Technology Co,.LTD.MaterialS355, S235, Steel, Stainless Steel, AluminumSizeCustomizedTolerance±0.1mmMeasuring equipmentArticulated Arm CMM ,CallipersSurface treatmentElectroplating, Anodization,Powder Coating, PaintingDrawing Format3D/CAD/Dwg/IGS/STPColorCustomizedApplicationMachinery, Construction,EquipmentSampleFree samples is available, customer pay the freightSample lead time20 daysBatch Lead time30 daysPackagingPallet, Woodenbox, Steel frameShipmentAir freight,Sea freight,Train,ExpressProduct DescriptionOur Advantages:1- As a direct manufacturer, we are able to offer more competitive pricing and superior service compared to trading companies. 2- Our workshop is equipped with top-tier machining and measuring equipment, ensuring strict quality control throughout the production process. 3- Boasting proprietary patents and unique technical expertise, we excel in manufacturing high-quality parts at a lower cost. 4- With rich industry experience and strong technical support, our engineering team comprises professionals with over 15 years of expertise. 5- We accept low minimum order quantities (MOQ) to accommodate your needs. 6- All products undergo 100% inspection prior to delivery to ensure quality. 7- Multiple transportation options are available from Shanghai to facilitate efficient delivery.Business workflowNo.ProcessDetails1Inquiry HandlingReceive your drawings/specs, conduct technical feasibility checks within 24hrs, and clarify details promptly.2QuotationProvide a detailed quote (price, lead time, terms) based on your requirements; adjust quickly if needed.3Order ConfirmationFinalize order with a formal contract upon your approval; start preparation after deposit receipt.4ProductionSource certified materials, execute CNC machining per standards, with in-process quality checks.5Quality Inspection100% final inspection against drawings/tolerances; issue inspection report.6ShipmentSecure packaging, arrange shipping from Shanghai (express/air/sea options), and handle customs docs.7After-Sales30-day quality warranty for machining-related issues; offer technical support and feedback follow-up.Quality Policy:1. Raw Material ControlSourcing: Cooperate with qualified suppliers ; demand material certificates (e.g., electrode/m wire test reports).Incoming Checks: Inspect welding materials for expiration dates, packaging integrity; verify base metal dimensions (using measuring tools) and surface conditions (visual checks for rust, cracks).2. In-Process ControlPre-Welding Setup: Welders confirm welding procedures (current, voltage, travel speed) match WPS; check equipment (welding machines, clamps) for proper functioning.Real-Time Checks: Monitor interpass temperature (infrared thermometers), weld bead shape (visual inspection), and root penetration (using ultrasonic testing for critical joints) every 30 minutes.Documentation: Record welding parameters, inspector comments, and any adjustments made to address issues promptly.3. Final InspectionWeld Integrity: non-destructive testing (NDT) including X-ray for internal defects, dye penetrant for surface cracks.Dimensional Checks: Measure weld dimensions (width, reinforcement) against drawings (using calipers, rulers) with tolerance within ±0.5mm.Mechanical Tests: Conduct tensile, bend, or impact tests on sample welds from each batch as required.4. Pre-Shipment InspectionBatch Sampling: Randomly select welds for rechecking of NDT results and dimensional accuracy.Surface Treatment: Ensure post-weld treatments (grinding, painting) meet standards; check for burrs, uneven surfaces.Docs: Attach welding inspection reports, NDT certificates, and material traceability records.Packing & DeliveryPacking Specs1. MaterialsOuter Packaging: Use sturdy steel-framed crates or fumigated wooden boxes (with certificate) based on product weight.Inner Protection: Wrap parts with anti-rust film; use foam pads for edges/corners to prevent collision.Fixing: Secure with steel straps; add braces inside to avoid shifting.2.
