Welding Engineering & Certification Services

At High Technology Nondestructive Testing Service Co., Ltd, we provide a holistic approach to welding quality. Our services go beyond simple inspection; we ensure that every weld is engineered for excellence, from initial procedure design to final welder certification.

1. Welding Supervision Services

Our certified Welding Supervisors and Coordinators act as your on-site quality guardians. We oversee the entire fabrication process to ensure strict adherence to project specifications and international codes.

• Real-time Monitoring: Monitoring pre-heating, interpass temperatures, and gas flow.

• Compliance Oversight: Ensuring that only approved materials, consumables, and qualified personnel are used on the shop floor.

• Defect Prevention: Identifying potential issues early to minimize rework and ensure structural integrity.

2. Welding Procedure Establishment (WPS & PQR)

We assist manufacturers in developing and validating technical documentation that forms the backbone of any welding project.

• WPS Development: Drafting Welding Procedure Specifications (WPS) tailored to your specific materials and applications.

• PQR Management: Coordinating Procedure Qualification Records (PQR), including the supervision of test coupons and destructive/non-destructive testing to verify mechanical properties.

• Code Compliance: Expertise in major standards including ASME Section IX, AWS D1.1, ISO 15614, and API 1104.

3. TPI Certification for Welders (WPQ)

As an independent Third-Party Inspection (TPI) provider, we offer unbiased qualification services to certify the skill levels of your welding workforce.

• Welder Performance Qualification (WPQ): Testing welders in various positions and processes (GMAW, GTAW, SMAW, SAW) to confirm their competence.

• Certification Issuance: Providing internationally recognized welder certificates that satisfy auditors and clients.

• Continuity Management: Helping firms maintain welder logs and re-certification schedules to remain audit-ready.
