Welding Engineering and Qualification Testing Services
Welding Engineering Services
Offered Monday – Friday, 8:00AM to 4:30PM
An Ohio State Welding Engineer will answer welding related questions and prepare qualification documents. Pricing for testing and consulting varies with the scope and volume of work required. Services we offer include:
Engineering Consulting can include reviewing your documentation, researching a topic, or troubleshooting a welding issue. (At an hourly rate)
Guidelines describe the material, joint and process requirements for a procedure or performance qualification, taking the guesswork out of what to do and what data to record.
WPS, PQR and WQTR/WPQ Preparation
- The Welding Procedure Specification (WPS), or procedure, specifies the range for each procedure essential variable.
- The Procedure Qualification record (PQR) is a record of what was done to qualify the procedure.
- The Welder Qualification Test Record (WQTR) or Welder Performance Qualification (WPQ) is a record of what they did to be qualified and the welder’s qualified range.
One of our qualified personnel will provide complimentary visual inspection for each welded sample, if delivered in person. Note: MIL-STD-3040 visual inspections are excluded, as they may incur an additional fee.
Guided Bend Testing
Using our BT1D bender with adjustable roller spacing, we can test any typical bend specimen. We have a variety of mandrel sizes, allowing us to test bend specimens in accordance with AWS D1.1, D1.2, D1.5, D1.6, D17.1, B2.1, ASME Section IX, API 1104, GCVWC 12479550, and other codes.
Wraparound Bend Testing
Using our wraparound bend tester, we can test dissimilar welds, aluminum samples, and other difficult-to-bend materials. Wrapping the bend specimen around the mandrel forces it to conform to the mandrel surface, preventing premature fracture.
The specimen in front was tested in a standard roller-guided bend tester and failed in the weld metal. The specimen in the back was tested in a wraparound guided bend tester and was acceptable. In both tests, the mandrel was 5 in. in diameter (per MIS-22151, Aircraft and Missile Welding Operator’s Qualification). Both specimens were removed from the same aluminum sample.
Using one of our tensile testers, we can test either welded samples or pre-prepared specimens in accordance with a variety of welding codes. Welded samples must be at least 12 in. wide and pre-prepared specimens must be at least 10 in. long.
