ASME Section IX Testing
Professional ASME welder qualification and certification services
Welder Qualification Services
Professional ASME Section IX welder qualification and certification services ensuring compliance with industry standards. Our qualified team provides comprehensive welder certification programs.
What is Welder Qualification?
Welder Qualification is the formal process of testing and certifying welders under ASME Section IX standards to ensure they possess the skills and knowledge required for critical welding applications.
At Tank Inspection Services, we do not perform welding — our role is to evaluate, test, and certify welders ensuring they meet industry standards before working on pressure vessels, piping, and other critical infrastructure.
Key Scope of Welder Qualification
Comprehensive testing and certification methods for ASME compliance
Welder Performance Qualification (WPQ)
Tests individual welder skills in accordance with ASME Section IX requirements.
Validates competency for specific welding processes and materials.
Procedure Qualification Record (PQR)
Documents the validation of welding procedures through mechanical testing.
Provides technical data supporting Welding Procedure Specifications.
Welding Procedure Specifications (WPS)
Qualification of welding procedures for specific applications and materials.
Ensures consistent welding quality across projects.
Bend Testing
Root bend, face bend, and side bend tests to evaluate weld quality.
Detects fusion defects, porosity, and other weld discontinuities.
Tensile Testing
Measures ultimate tensile strength of completed weld joints.
Verifies weld strength meets or exceeds base material requirements.
Multiple Process Certification
SMAW, GTAW, GMAW, FCAW, and SAW process qualifications.
Comprehensive testing across various welding positions and materials.
Why It Matters
Welder qualification is essential for ensuring safety, compliance, and quality in critical welding operations
Standards Compliance
Ensures welders meet ASME Section IX requirements for critical applications.
Documentation & Certification
Provides verified documentation of welder competency and skill level.
Risk Reduction
Reduces risk of weld failures through proper testing and validation.
Quality Assurance
Maintains consistent weld quality across all project phases.
Frequently Asked Questions
Common questions about Welder Qualification services
WPQ (Welder Performance Qualification) tests individual welder skills and competency for specific processes and positions, while PQR (Procedure Qualification Record) documents the mechanical testing results that validate welding procedures. A WPQ qualifies the welder, while a PQR qualifies the welding procedure itself.
Under ASME Section IX, welder qualifications remain valid indefinitely as long as the welder continues to weld with the qualified process. However, if there's a gap of 6 months or more without welding, or if there's reason to question the welder's ability, requalification may be required. Many companies also require periodic requalification for quality assurance.
ASME Section IX covers all major welding processes including SMAW (Stick), GTAW (TIG), GMAW (MIG), FCAW (Flux Core), SAW (Submerged Arc), PAW (Plasma Arc), and others. Each process requires specific qualification testing, and qualifications are process-specific - qualifying in one process doesn't automatically qualify a welder in another.
ASME Section IX defines specific welding positions: 1G (flat), 2G (horizontal), 3G (vertical), and 4G (overhead) for groove welds, and 1F, 2F, 3F, 4F, and 5F for fillet welds. Qualifying in a higher position typically qualifies the welder for lower positions - for example, passing 6G (pipe) qualifies for all other positions.
Testing typically includes visual examination of the completed weld, followed by destructive testing such as bend tests (root, face, or side bends), tensile tests, and sometimes impact tests depending on the application. The specific tests required depend on the material thickness, welding process, and intended service conditions of the final weldment.
