BQCIS

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.
