Energy storage welding simulation

Which simulation method is used for welding a large component?

Long, large, and frequently accompanied by irregular shapes, the welds of large components lead to a steep increase in the number of meshes of large engineering components. The thermal-elastoplastic finite element method and the inherent strain method are the most widely used simulation techniques for welding.

Why is welding simulation important?

Therefore, achieving accurate welding simulation to predict and effectively control welding deformation of substantial engineering structural parts is essential to ensure welding quality and improve production efficiency.

What are the challenges posed by welding simulations for large structural components?

The challenges posed by cross-scale effects, large computational requirements, high nonlinearity, and complex interactions of multiple physical phenomena constitute major obstacles to the effectiveness and accuracy of welding simulations for large structural components.

Can welding simulation predict the distribution of deformation and residual stress?

Currently, welding simulation is the most extensively employed method for predicting the distribution of welding deformation and residual stress in large and complex engineering structures . However, welding simulation has always encountered obstacles, mainly reflected in 1) difficulties in pre-processing welding models.

What is the future development of welding numerical simulation?

The future development of welding numerical simulation will focus on balancing simulation accuracy and simulation efficiency and optimizing welding parameters to control welding deformation efficiently. 1. Introduction

How can a numerical simulation be used to predict welding deformation?

For predicting the spatial distribution of welding deformation and remaining stress across large components, numerical simulation techniques can reduce experimental costs, meet actual production requirements, and abbreviate the process cycle by substituting welding experiments.
