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)
