AI-Powered supplier vetting

SummaryGuangzhou Dragon Welding Co., Limited is identified as a Chinese manufacturer/factory in Guangdong producing a broad range of welding, wire-processing, and related machinery. The supplier states that its products are exported to multiple international markets and that it provides professional sales and timely after-sales service, but detailed service infrastructure is not verified. ISO 9001 certification, 6–10 R&D engineers, 6–10 quality-control staff, and more than 10 production lines indicate established quality and manufacturing resources. A BV audit is documented as valid from May 22, 2025 to May 21, 2026. Evidence for OEM/ODM, 3D design, product-development activity, overseas facilities, raw-material traceability, and sustainability systems is unavailable. One associated buyer is identified, while broader customer-case evidence remains limited.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and is identified as Guangzhou Dragon Welding Co., Limited, based in Guangdong, China. Its listed primary products include multiple welding and wire-processing machine categories, supporting a direct manufacturing profile.

CertificationsThe supplier states that it holds a European CE Certificate, and ISO 9001 management-system certification is explicitly listed. A BV audit is also recorded with a stated validity period from May 22, 2025 to May 21, 2026, providing additional documented assessment evidence.

After-Sales capabilityThe company description explicitly claims professional sales and timely after-sales service and says it has built long-term cooperation with many customers. However, the available information does not verify overseas service locations, warehouses, showrooms, agents, or branches.

Production capacityThe supplier operates more than 10 production lines, employs 6–10 quality-control staff, and offers a broad portfolio of welding and wire-processing machinery. The documented product specification for a numerical-control bending machine further demonstrates defined manufacturing output, although capacity volume is not independently verified.

Client casesThe supplier states that it has exported to Italy, Germany, Russia, the United States, Canada, Argentina, Peru, Turkey, South Asia, and Middle Eastern countries, and one associated buyer is listed. It also claims long-term cooperation with many customers, but named customer-case detail and Fortune 500 cooperation are not verified.
