Above: Water-cooled jaws contribute to very fast cooling rates and enable researchers to simulate steep thermal gradients found in welding applications.

Additional grip models are available to support uniform hot zone and other requirements.

Current Gleeble systems including the Gleeble 3500 and 3800 are very versatile and offer a wide range of simulations and tests. The new Gleeble Welding Simulator has been designed from the ground up with the needs of welding researchers in mind. The capabilities of this system are customized to meet those needs.

Below are some of the simulations this new system offers: 

Material Testing Simulations:

  • Weld HAZ Simulation
  • Nil Strength Testing
  • Charpy Specimen Heat Treatment
  • Hot Ductility and Tensile Testing
  • Melting and Solidification
  • Study of Local Brittle Zones
  • Embrittlement and Crack susceptibility
  • Strain Induced Crack Opening (SICO)
  • Post-Weld Heat Treating

Process Simulations:

  • GMAW - Gas Metal Arc Welding
  • GTAW - Gas Tungsten Arc Welding
  • SAW - Submerged Arc Welding
  • ESW - Electroslag Welding
  • Welding of Ferrous and Non-Ferrous Materials
  • Diffusion Bonding
  • Laser Welding
  • Upset Welding
  • Post Weld Heat Treatment
    • Stress Relieving
    • Aging Characterization
    • Annealing

 

HAZ Simulation:
One of the most popular types of welding research conducted on the Gleeble is HAZ Simulation. The Gleeble recreates specific sections of the HAZ based on the programmed thermal and mechanical cycle.

The microstructural gradients and residual stresses created by the rapid heating and cooling found in welding can be reproduced in a controlled laboratory setting. 

The Gleeble can be used to create large enough sections of HAZ material for subsequent mechanical properties testing.


Mechanical Specifications:
The Gleeble Welding Simulator offers a high speed mechanical system with unmatched performance in its class. The innovative hydraulic system results in a servo system capable of 200 millimeters per second stroke rate with precise control and measurement accuracy.

Below: The vacuum tank of the Gleeble Welding Simulator contains a water-cooled jaw carrier which delivers electric current to copper grips, enabling very fast heating and cooling of the specimen.
