Simulation laser welding using Dflux subroutine Abaqus
In this example , we intend to simulate laser welding process using Dflux subroutine in the Abaqus software
We use volumetric heat flux for simulation of the welding process, and we use cylindrical involution normal (CIN) heat source model for define volumetric heat flux, and we use the Dflux subroutine for define cylindrical involution normal (CIN) heat source 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 4 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, the welding speed is 50mm/s
cylindrical involution normal (CIN) heat source model is adopted to calculate volumetric heat flux distributions as heat input around the welding pool
Equation of the (C-I-N) heat source model is defined as a function of position and time together with a number of parameters
The solidus temperature is 1400 °C and the liquidus temperature is 1454 °C
