Demonstrating Excellence in Welding Fabrication
ISO 3834 defines quality requirements for fusion welding of metallic materials. Certification confirms that your organization maintains robust controls and qualified personnel capable of delivering consistent welded-product quality.
Unlike individual welder or procedure qualifications, ISO 3834 certifies the entire welding quality management system—covering contract review, competence, equipment maintenance, consumables control, inspection and testing, and non-conformance handling.
BQCIS performs accredited audits against ISO 3834 Parts 2 (Comprehensive), 3 (Standard), and 4 (Elementary). Certification assures clients and regulators that your welding operations are capable and compliant with international standards.
Key ISO 3834 Audit Activities
System & Documentation Review
Auditing welding manuals, WPS/PQR records, welder qualifications, inspection plans, and equipment calibration to verify system control and compliance.
Implementation Assessment
Observing welding operations, verifying procedure adherence, consumable control, and competence of welding coordinators and inspectors during production.
Key Benefits of ISO 3834 Certification
Assure Consistent Weld Quality
Confirms your welding operations are systematically controlled and meet defined quality standards.
Meet Contractual Requirements
Recognized by major clients and standards such as EN 1090 and PED, often mandated for supplier qualification.
Reduce Rework & Failures
Prevents defects and rework through systematic process control, leading to higher efficiency and lower cost.
Enhance Market Reputation
Demonstrates technical competence and commitment to international welding quality standards.
Success Story
ISO 3834 Certification Empowers Structural Fabricator
A steel fabricator sought to qualify for projects requiring EN 1090 CE Marking, which mandates ISO 3834 certification for welding quality systems.
BQCIS performed a gap analysis and certification audit against ISO 3834-2, verifying welding coordination, qualifications, and quality records.
The company achieved ISO 3834 certification, enhancing its credibility and unlocking eligibility for high-spec engineering contracts across Europe.
