// Overview
International welding quality certification for manufacturing excellence
In today’s competitive fabrication and manufacturing industry, quality welding is not just a requirement — it is a critical factor for safety, compliance and customer satisfaction. ISO 3834, Quality Requirements for Fusion Welding of Metallic Materials, is the internationally recognised standard that defines comprehensive quality requirements for welding processes.
At WeldFab Tech we provide end-to-end ISO 3834 certification consultancy, pre-audit assessment, documentation support, training, implementation and certification assistance to help organisations achieve global recognition and meet customer and statutory requirements.
Whether you are a pressure vessel manufacturer, structural steel fabricator, shipbuilder, railway manufacturer, oil & gas contractor, heavy engineering company or EPC contractor, our experts ensure a smooth certification journey from gap analysis to successful certification.
Certification provides confidence to customers, consultants, EPC companies and international buyers that your welding operations comply with globally accepted quality requirements.

What is ISO 3834?
ISO 3834 is an internationally accepted quality management standard developed specifically for organisations involved in fusion welding of metallic materials. Unlike a general quality management system, it focuses entirely on welding quality, establishing requirements for:
- Welding coordination
- Qualified welding personnel
- Welding Procedure Specifications (WPS)
- Procedure Qualification Records (PQR)
- Welder Qualification (WPQ)
- Welding consumable control
- Material traceability
- Inspection & testing
- Non-Destructive Testing (NDT)
- Equipment calibration and maintenance
- Welding documentation
- Quality records and compliance

Choosing the level
The level follows the criticality of what you fabricate. Certifying higher than the work requires costs more to maintain without winning more work.
LevelTypical scope
- ISO 3834-2 — Comprehensive
Pressure equipment and safety-critical fabrication
- ISO 3834-3 — Standard
General structural fabrication
- ISO 3834-4 — Elementary
Simple, non-critical work
