Testing Capabilities
The Center for Weldability Evaluation resides at Ohio State's Welding Engineering Laboratory and utilizes unique tools and methods for weldability testing and evaluation and phase transformation analysis that have been invented, developed, and/or improved at our facility.
On-site testing capabilities offered
- New generation Cast Pin Tear Test
- Newly developed Delayed Hydrogen Cracking Test (under standardization with NACE)
- Patented technique for single sensor differential thermal analysis
- Transvarestraint test
- Implant test
Gleeble™ Thermo-mechanical Simulator
The Welding Engineering Laboratory at The Ohio State University houses a Gleeble 3800 system. The fee-based system has been extensively used to support academic and industry research and development.
The Gleeble thermo-mechanical simulator can be used for running precisely controlled heat-treatments or thermo-mechanical testing of specimens in an inert or vacuum atmosphere.
Gleeble-based tests
-
Stress Relief Cracking
-
Fixed Displacement Thermal Cycling
-
Strain to Fracture
-
Strain-age Cracking
-
Hot Ductility
- Dilatometry
These weldability tests are supplemented with computational models, physical simulations, and advanced metallurgical characterization, resulting in the quantification of alloy-specific properties related to weldability. Such properties can be utilized in computational models of welding processes to predict crack-free welding conditions and prevent loss of properties and weld failures during manufacturing and service.
The CWE utilizes additional mechanical testing facilities available within the Department of Materials Science and Engineering and the Center for Design and Manufacturing Excellence (CDME), and the advanced metallurgical characterization facilities of the Center for Electron Microscopy and Analysis (CEMAS).
