Physical simulation

At SLV M-V GmbH, it is possible to carry out welding simulations as well as simulations of thermomechanical processes.

Equipment

  • Gleeble 3500 testing machine for thermal/thermomechanical tests
  • Control console and PC with corresponding software for controlling the simulation and evaluation
  • Hydraulic pump
  • Mechanical system with 10t for tensile/compression tests
  • Standard clamping for different specimen shapes
  • Tactile recording of transverse strain
  • Cooler, compressor, vacuum pump, high-flow quench system/pressurized water reservoir, spray jaws, thermocoupler
  • Software-controlled simulation (QUICKSIM) and evaluation (ORIGIN)   

Special features

  • Heating rates of up to 6000K/s possible, depending on material and sample size/shape
  • Inertia-free optical recording of transverse strain, in planning by means of a light-band micrometer
  • Tactile recording of longitudinal strain
  • Maximum test force 100kN
  • Software for predetermining suitable specimen shape/temperature curves in testing

Investigations

  • Simulation of conventional and beam welding processes
  • Creation of welding ZTU diagrams, including simulation on individual samples
  • Assessment of welding suitability
  • Determination of the microstructure composition and mechanical properties for the HAZ at RT
  • Location and temperature-dependent microstructure and property determination
  • Study of diffusion processes
  • Measurement of dilatation (thermal expansion coefficient)
  • Measurement of thermal-physical parameters (thermal diffusivity, thermal conductivity) is commissioned
  • Carrying out hot tensile and compression tests
  • Determination of yield stresses and modulus of elasticity
  • Simulation of heat treatment measures
  • Thermal shock resistance, also of coated samples; thermal fatigue
  • Creep tests
  • Low cycle fatigue (constant temp.)
  • Testing of susceptibility to hot cracking possible
  • Simulation of any other thermomechanical cycles (e.g. comparison with FE calculations)
