6 FAQs about [Energy storage welding thermal simulation]

How do you speed up a weld simulation?

o speed up the simulation is to use a thermal dumping technique. This type of method involves dumping the thermal energy from the weld source in one or a limited number of steps. The incremental heat source movement simulation is then bypass d, and the simulation time is reduced to the cooling simulation. Th

What is thermal cycle simulation of welding?

Investigation of weldability by thermal cycle simulation of welding is an accelerated testing procedure that provides quantitative indicators of weldability in the heat-affected zone of the welded joint.

Why is thermal cycle simulation important?

Thermal cycle simulation of welding significantly shortens the process of selecting optimal welding parameters and attesting the welding procedure, and it also reduces total costs of weldability testing.

What is the maximum temperature for a single-pass welding simulation?

Single-pass welding simulations usually focus on investigation of thermal cycles with a maximum temperature between 1200 °C and 1350 °C. The authors of this paper performed researches into thermal cycles with the maximum temperature of 1350 do 1380 °C.

Can a weld thermal cycle simulation be used to test welded materials?

Over the past period, the authors applied the weld thermal cycle simulation in testing of weldability of different materials (micro-alloyed steels Nioval 50, TStE 420, high-strength steels S1100QL, as well as T/P 91, T/P 92, etc.).

Can a weld simulation be thermo-mechanical?

in just one step. This methodology is known as thermal dumping. This is true if it can be assumed that the deformations and str sses that occur during the heating does not affect the solution. Thus, th stresses and deformation evolve during the coo ing of the weld. Still, the simulation can be thermo-mechanical. It is then possible to
