Welder Testing Services

TechCorr's Welder Testing Services verify that welders and welding procedures meet the code, specification, and quality requirements demanded by critical energy infrastructure. From welder performance qualification to procedure review and weld inspection, we provide the testing and documentation that owners, constructors, and regulators rely on to confirm welding integrity.

Welder Performance Qualification

We conduct and document welder performance qualification (WPQ) testing to demonstrate that each welder can produce sound welds meeting the requirements of the applicable code. Testing includes:

• Coupon preparation and welding under controlled, witnessed conditions.
• Visual and dimensional inspection of completed test welds.
• Destructive and non-destructive testing — bend tests, tensile tests, and NDE (radiography, ultrasonic, magnetic particle) as required by the procedure and code.
• WPQ documentation — traceable qualification records that support project and regulatory acceptance.

Welding Procedure Qualification

We review and support qualification of Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) to ASME Section IX, API 1104, API 577, and client-specific requirements — confirming that proposed procedures are capable of producing sound, code-compliant welds.

Codes & Standards

Our welding inspectors and personnel are experienced with ASME, API, AWS, and client specifications across piping, pressure vessels, structural, and pipeline applications. We align testing scope with the governing code and project specification to deliver qualifications that are accepted by owners and regulators.

Documentation

Every qualification is supported by complete, traceable documentation — test reports, inspection records, and qualification documents — giving you a defensible record that welding personnel and procedures meet requirements.
