Finite Element Simulation of Brazing

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Brazing is a thermal joining process which connects metal components with melted filler material. The filler usually has lower melting point compared to components. Main advantages of brazing lies in relatively low heat input and the capability to create a joint of considerable strength and durability.

Enteknograte engineers simulate the Welding with innovative CAE and virtual prototyping available in the non-linear structural codes LS-DYNA, Ansys, Comsol, Simufact Welding and ABAQUS. We are experienced with FEA Welding simulation.

Enteknograte Engineers can simulate any type of welding such as Arc Welding, laser Beam Welding, RSW, FSW and transfer the results of welding simulation for next simulation like NVH, Crash test, Tension, Compression, shear test and fatigue simulation.

Welding cause to The components, commonly made of steel(s), are temporarily heated to specific temperatures Distribution. Taking into account the rate of heating and cooling, the material properties of a component can be altered and improved. The presence of certain agents can lead to changes in the carbon or nitrogen content of the component. In all welding processes, there are several decisive and important factors: Time (heating and holding time), temperature, atmosphere, and quenching or cooling conditions. In principle, there are two kinds of welding effect as heat treatment processes on material points:

  • processes resulting in a thorough change of the microstructure such as annealing and hardening

  • processes that result in merely changing regions close to the surface of the component such as diffusion and coating processes, carburization, case hardening, nitrating, boriding

Enteknograte Engineers simulate any type of welding with any level of complexity:

Arc Welding
• Electron Beam Welding
• Laser Beam Welding
• RSW (Resistance Spot Welding)
• FSW (Friction Stir Welding)
• Pressure Welding
• Stress Relief Heat Treatment

Why we use Simufact as default for welding simulation

Simufact Welding predicts distortions and residual stresses by virtually try-outs and helps the user to determine appropriate strategies to minimize them. It is the only simulation software which automatically considers the complex contact situation between the components, which in turn allows conclusions about the properties of the weld seam, in particular its strength, to be drawn. Simufact Welding achieves this by calculating the microstructural properties within the heat-affected zone, which also gives the user a valuable insight into identifying welding defects, such as hot cracks in the simulation, and how to avoid them in practice.

 

 

Resistance Spot Welding: Finite Element Simulation of RSW

Resistance Spot Welding is a pressure welding process during which the sheets are pressed together locally with the help of fitted copper electrode welding guns. The electrical current between the weld guns causes a heating and melting of the joining partners, creating a small circular welded area between them.The standard approach in a RSW model contains fully coupled electrical, thermal, metallurgical and mechanical steps, so the heat generation is calculated due to Joule’s heating coming from electrical current and resistivity between components.

Finite Element Simulation of Arc Welding

Arc welding processes (SMAW, GMAW [MIG], GTAW [TIG], SAW, …) are of the highest economic importance due to their flexible application and relatively low equipment costs for both robotic and/ or manually controlled joining. Due to a high melting rate and a high gap-bridging ability these processes are found most notably, in steel plants, power stations and shipbuilding.

Pressure Welding FEA Simulation: Friction welding, Resistance welding, Friction spot welding

Pressure welding is a group of diffrent joining processes which have all in common that the components are joined by applying heat and pressure. The heat can either be generated by an electrical current flow (resistance welding) or by friction (friction welding).

Finite Element Simulation of Laser Beam / Electron Beam Welding

Laser Beam welding is a thermal joining process, in which a component is heated and welded by a laser beam. It is a high-end process for application cases requiring the highest degree of precision. A huge advantage of laser beam welding lies in the relatively narrow heat affected zone. Electron Beam welding is a thermal joining process, in which a component is heated and welded by electron beam.

Vibration Fatigue Finite Element Simulation: Time & Frequency Domain

Structural vibration can be a source for many product related problems; it can cause fatigue and durability problems as well as adverse reactions to the user or bystanders in the form of undesirable vibrations that can be felt or heard. As well, undesired structural vibrations can prevent products from operating as required and potentially becoming a safety concern. The Vibration Fatigue simulation predict fatigue in the frequency domain and it is more realistic and efficient than time-domain analysis for many applications with random loading such as wind and wave loads.

Integrated Artificial Intelligence (AI) & Machine Learning - Deep Learning with CFD & FEA Simulation

Machine learning is a method of data analysis that automates analytical model building. It is a branch of Artificial Intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. With Artificial Intelligence (AI) applications in CAE, that is Mechanical Engineering and FEA and CFD Simulations as design tools, our CAE engineers evaluate the possible changes (and limits) coming from Machine learning, whether Deep Learning (DL), or Support vector machine (SVM) or even Genetic algorithms to specify definitive influence in some optimization problems and the solution of complex systems.
