Description

Simulation arc welding using Dflux subroutine Abaqus

In this example , we intend to simulate arc welding process using Dflux subroutine in Abaqus software

We use volumetric heat flux for simulation of the welding process, and we use Goldak’s double-ellipsoid model for define volumetric heat flux, and we use the Dflux subroutine for define Goldak’s double-ellipsoid model

Dflux subroutine is used to define nonuniform heat flux

This problem is done in two steps

In step1 , we simulate welding process with duration of 20 seconds

In step2 , we simulate cooling process with duration of 120 seconds

To do so , we define two Coupled temp-displacement step

The material of the plate is SUS304

Density, thermal conductivity, specific heat, thermal expansion, elastic properties and plastic properties depend on the temperature

In this example , welding voltage is 22 volt , welding current is 110 ampere , efficiency is 0.8 , welding speed is 10mm/s

Goldak’s double-ellipsoid heat source model is adopted to calculate volumetric heat flux distributions as heat input around the welding pool

Equations of the Goldak’s heat source model is defined as a function of position and time together with a number of parameters

The constants a,b,Cf,Cr as shown in picture are heat source parameters that define the size and shape of the ellipses and these parameters are obtained from experimental analysis
You can see Residual Stress (S33)

longitudinal residual stresses (residual stress in welding path)

transversal residual stresses(residual stress in perpendicular to the welding path)
