1. Geometry and mesh

 

2. Material properties: SM400A

 

3. Heat source model

The heat input to the work piece can be divided into two portions: One is the heat of the welding arc, and the other is that of the molten metal droplets

The heat of the welding arc is modeled by a surface heat source with a Gaussian distribution

4. Boundary conditions

5. Results

Melting pool (beyond 1500 degree)

Temperature at measure points
